Best way to compare Wired Router with Wireless Router
If you use computer systems at home or even workplace, chances are your personal computer is actually linked to some other computer systems through some sort of modem. Being a officer leading traffic at an interchange, the router will direct or even course details, data and also files for the areas they should move. Typically, Hubs that individuals used can either end up being born or perhaps cellular.
The wired modem will generally connect to your pc and computers or even hardware through an Ethernet cable tv. This occurs by using result ports. And also the simply enter interface offered over a hub is going to be used for the net.
A wireless hub may possibly allow accessibility from the 3 computer systems by means of born Ethernet cabling and throughout cellular contacts. You knows the hub you use is actually wifi when it comes with a antenna. The aerial will provide the particular modem having a specific range that enables additional computer systems in the area with cellular capabilities to access the router, provided they possess security password accessibility.
As being a circle manufacture, have you got possible opportunity to use actual physical gear? Very can be not often, wish to consider reveal this information together with those who find themselves serious about getting accustomed to the particular physical Cisco tools. We will consider the Cisco 2901 as an example.
Cisco's Integrated Program Modems (ISR) are usually employed by most tiny organizations. These types of routers are designed to be described as a common intent, variable alternative for many different situations that will assistance several different functionality coming from easy nav to World-wide-web protocol and also video conferencing. The Cisco 2901 router may be the champion in order to Cisco's 2500, 2600 along with 2800 string collections of hubs. It really is 1RU (Stand Device) in size and is also known as a new 'pizza box' router.
The particular figure under reveals an image in the front and back of the 2901 router:
In the following paragraphs we will concentrate on the components startup of the Cisco hub. There are a variety of various element possibilities that are available with the 2901. The whole picture previously mentioned is of a 2901 without extra modules set up. First of all , any kind of professional should do with modem (or even new at all to all of them) would be to configure increase that in order to meet the demands of it is supposed purpose inside community.
To get this done the particular engineer need to hook up a cable tv for the Cisco 2901/K9 to get into the particular unit from the product. Having older routers your best option whenever connecting towards the gaming console seemed to be using a tailor made flip cable tv that was next used in in conjunction with a new RJ-45 in order to DB-9 or perhaps DB-25 converter which often enabled appreciable link that has a successive vent using a Personal computer. Considering that most more recent PCs (which include netbooks) don't get standard serialized slots a lot of companies are suffering from Hardware to help successive wire plugs which permit appreciable link to these more mature units by way of a modern-day Flash dock. This 2901 has a pair of diverse obtainable ways of association; through the old design RJ-45 slot and also a roll-over wire Or even via a direct mini-USB link with the device.
Note:As another wonderful Cisco router, CISCO2921/K9 delivers highly secure data, voice, video, and application services for small offices.

CISCO1921/Cisco 1941 is usually to switch the very well liked Cisco 1841 router. Cisco 1841 has stopped being being offered and might not be reinforced. Cisco 1921, new certification as well as software program, (possibly) much better effectiveness as well as assistance for brand new modules--it dominates your Cisco 1841 and former decades connected with part company wireless routers.
So here let's have an overview with Cisco 1841 in addition to Cisco 1921, to find out the main difference between them. Exactly why 'cisco' 1921 is the foremost replace Cisco 1841 router currently?
CISCO1841-The Current Regular
1RU, 20 inches sheet mountable, one power, 256 Megabytes DRAM in addition to Sixty-four MB inner thumb.
2 times HWIC slot machine games (only one FE as well as Whirlpool HWIC may be used each time)
The particular Cisco1841 has a incorporated Virtual private network processor chip regarding IPsec VPN and also the replacement for include the Target greeting card intended for SSL Virtual private network functionality, nevertheless the 1841 doesn't have tone of voice features--it's not well suited for words portal or perhaps get in touch with administrator software. Nonetheless, when you have a Sip trunks footwear and other World-wide-web protocol files association, the actual 1841 does indeed service passing Above boxes through, together with quite strong QoS you prioritized the particular Voice over internet protocol visitors.
CISCO1921-The Next Generation Router
1 RU, 19 inch rackmountable, single power supply, 512 MB DRAM, 256 MB internal flash
The actual Cisco 1921/K9 modem provides bundled IPsec and also SSL VPN assist along with replaced software program, but such as the 'cisco' 1841, this 'cisco' 1921 can not be employed being a Call Manager or even voice entry (but can even now cross World-wide-web protocol packages by way of).
Completely new in addition to Basic Software
The revolutionary hubs now use licence recommendations as well as a common graphic to look for the offered functions, in much the same to be a Pics or ASA. This fresh licensing structure also offers the main advantage of producing a clear department relating to the sort of IOS set up plus the feature set installed, in order to update the actual IOS variation without in contact with the actual feature set part, as well as up grade your set of features on a modem without having pressing your IOS file.
Also, the certification framework may be even more streamlined, currently leaving us all merely Three attributes packages, not one that overlap.
Here are the contents of each available feature package:
IP Base: The default feature set; has support for common routing protocols (RIP, OSPF, EIGRP, BGP), common WAN technologies (MLPPP, MLFR), and common LAN technologies (802.1q trunking). No VPN, firewall, or voice features are present.
Data: The Data license adds support for MPLS, ATM, IS-IS, and non-IP L3 protocols.
Security: The Security feature set adds IPSec VPN capabilities, SSL VPN capabilities, and IOS firewall features.
So Cisco 1921 router is a fantastic device, but with similar limitations to its predecessors-it has only a single power supply and no feature set for voice.
For those that really need the last degree of performance, however, and can live with its limitations it is a good evolutionary step forward from previous generations of small routers.

How to Configure DHCP Server on Cisco Routers and Switches with Cisco IOS?
DHCP, Dynamic Host Configuration
Protocol is the protocol used by network devices like a PC or a printer
(DHCP clients) to obtain IP Address, Default Gateway, Domain Name, DNS Servers,
NetBIOS servers and more that helps the device to work properly in an IP Network.
While in an ideal scenario, most if not all
organizations run the DHCP server on a Windows server or a Linux/Unix
server. While this is justifiable in bigger corporate and enterprise networks,
a smaller network like a branch office can be supported by a local Router,
Switch or a Firewall can run a DHCP server without the need of an additional
server hardware to run DHCP. Most of the routers, firewalls and some switches
do have a DHCP server built-in. Most of the new Cisco Routers and Switches running
Cisco IOS can run a DHCP server.
The following procedure helps you to setup
a Cisco Router or a Catalyst Switch as DHCP server (I use a Cisco Router here):
Enable DHCP Service on the Router
dhcp-router# conf
t
dhcp-router(config)#
service dhcp
Create DHCP IP Pool
dhcp-router(config)#
ipdhcp pool IP-POOL
NOTE: Where IP-POOL is the name of the DHCP
IP Pool
Cisco IOS, The World's leading Network Infrastructure Software
Whats the Cisco IOS? Cisco IOS (originally Internetwork Operating System) is the software used on the vast majority of Cisco Systems routers and current Cisco network switches. (Earlier switches ran CatOS.)
IOS is a package of routing, switching, internetworking and telecommunications functions tightly integrated with a multitasking operating system.
The IOS CLI provides a fixed set of multiple-word commands the set available is determined by the "mode" and the privilege level of the current user. "Global configuration mode" provides commands to change the system's configuration, and "interface configuration mode" provides commands to change the configuration of a specific interface. All commands are assigned a privilege level, from 0 to 15, and can only be accessed by users with the necessary privilege. Through the CLI, the commands available to each privilege level can be defined.
Cisco IOS is versioned using three numbers and some letters, in the general form a.b(c.d)e, where: a is the major version number. b is the minor version number. c is the release number, which begins at one and increments as new releases in the same a.b train are released. d(omitted from general releases) is the interim build number. e (zero, one or two letters) is the release train identifier, such as none (which designates the mainline, see below), T (for Technology), E (for Enterprise), S (for Service provider), XA as a special functionality train, XB as a different special functionality train, etc.
Most Cisco products that run IOS also have one or more "feature sets" or "packages", typically eight packages for Cisco routers and five packages for Cisco network switches. For example, Cisco IOS releases meant for use on Catalyst switches are available as "standard" versions (providing only basic IP routing), "enhanced" versions, which provide full IPv4 routing support, and "advanced IP services" versions, which provide the enhanced features as well as IPv6 support. Each individual package corresponds to one service category, such asIP data, Converged voice and data, Security and VPN.

A&Q about Cisco IOS (from Yahoo Answer) Q: Help needed to upgrade my cisco switch ios? I have connected my switch via console cable, I have set up a tftp server on my PC when I try to update the ios it keeps timing out.
A:First, your computer with the tftp server and the switch need to be connected via the network. When the switch pulls the image, it's not through the console cable, but rather an ethernet port. Second, your new IOS image needs to be in the correct folder on your local hard drive so the tftp server can reach the file and serve it to clients that ask. This varies greatly by tftp server, so I can't give you clear directions for how to do this. Third, your switch needs an IP address assigned to a vlan interface. Typically, vlan 1 is used, but more advanced users can use a different one. The configuration usually looks like: configure terminal interfacevlan 1 ip address w.x.y.z 255.255.255.0 no shut end To do a little troubleshooting, try pinging your computer from the switch and then ping the switch from your computer. Due to firewalls, this may or may not work, but it's a good tool. Lastly, once you are sure that connectivity is in place, you issue the command "copy tftp flash" from the switch. The switch will ask you the IP address of the tftp server, then the filename, and then it will probably ask you if you want to erase the flash. You should usually press "enter" to confirm "yes" to erase the flash, otherwise you'll run out of room in the memory. If you do not receive the question to erase the flash, that means there is a connectivity issue. Hope this helps.
Q: How I can install IOS into cisco switch 3560 series? In my cisco switch 3560 series hasn't IOS system and I cann't into priveleged EXEC mode. "enable" function cann't run!
A: The first thing you need to do is recover the password so you can "enable" privileged mode - you need to "break" as the switch is about to load 1/ Put the new IOS onto a tftp server (if you don't have one, google for "tftp server free download"). 2/ Get the switch onto the same network as your tftp server. 3/ decide if you have enough room in either flash or RAM (depending on your switch) and copytftp flash
Cisco IOS Download Tips Generally, if you want to download or upgrade Cisco IOS while having a used Cisco router or didnt buy Cisco router, options offered here will help you get the Cisco IOS: 1. Download the Cisco IOS from somewhere like a bit torrent or a file sharing program. 2. Purchase a maintenance contract for the hardware and download the software. 3. Buy the IOS from a reseller. (The cost of the software will vary based on the model of the router you are buying it for and the features of the OS you are wanting.)
How to Upgrade Cisco IOS Software in a Router or a Switch
Upgrading IOS on buy cisco routers and switches is highly recommendable because of the following reasons
Patch critical vulnerabilities: Just like any other network device or application, Cisco routers and switches are also prone to security holes. And because routers and switches are critical to network infrastructure, you should plug these security holes as soon as possible.
Incorporate new features: Unless an update is simply a bug fix, every new release of the Cisco IOS includes new features. Upgrading your buy used router and switches in a timely manner means youll have more features to potentially make your job easier.
Stay current: Staying current with the latest IOS may sound like a flimsy justification to upgrade, especially when you consider your daily task list. However, when you consider the many different tools that communicate with the routers IOS, staying current can take on a new importance. For example, if youre using a SNMP network management tool, it may require your router to run a certain version of the IOS.
Procedure to upgrade cisco IOS NOTE:Before doing any upgrades plesae take a complete backup of your cisco device configuration for safer side
Download the Correct version of Cisco IOS for you from here
Write Unsaved configurations
ciscorouter# write memory Building configuration [OK]
Check space on Flash Memory
ciscorouter# show flash
Make sure you have the space left on your cisco device.
Backup Startup Configuration
Setup a TFTP server in the same IP range as the refurbished cisco router device to backup the configs, IOS image and also for later to upload the new IOS image.
testrouter# copy startup-configtftp Address or name of remote host []? 10.10.10.2 Destination filename [startup-config]? !! 1278 bytes c opied in 0.100 secs
Backup Current IOS Image
testrouter# copy flash: tftp: Source filename []?xxxxx-xx-xx.121-x.XB Address or name of remote host []? 10.10.10.2 Destination filename [xxxxx-xx-xx.121-x.XB]?
Now, Load the new IOS image from the TFTP onto the flash
ciscorouter#copytftp: flash: Address or name of remote host []? 10.10.10.2 Source filename []?c3560-ipbasek9-mz.122-40.SE.bin Destination filename [c3560-ipbasek9-mz.122-40.SE.bin]?

IPv6 address a lot concerns and issues that are faced today in using IPv4. Cisco CCNA Certification
requires that a candidate must have a general overview of IPv6 and what
new features it brings into the world of networking. Here we will go
through some of the features of Internet Protocol Version 6 (IPv6).
The main feature of IPv6 are described in the sections below
Larger Address Space
IPv6 addresses are 128-bits long which gives us a theoretical address space of 3.4 x 1038
addresses, like IPv4 some address space is reserved for special purpose
but still there is a huge number of public routable addresses.
Aggregation
A larger address space allows for large address allocations to ISPs
and Organization. This allows them to use a single prefix for the entire
network making summarization easy and flexible which turn promotes
efficient and scalable routing.
New Improved Header Format
Optional and non-essential fields are removed from the IPv6 Header
and are moved the Extension Header that is placed after the IPv6 Header.
Fewer fields of fixed lengths mean Header overhead is minimized and
processing performance is improved. Another significant enhancement is
that all routers in a path do need to do checksum recalculation for an
IPv6 Packet instead error detection is handled by data-link layer
technologies checksums of the end-to-end connection at transport layer.
Figure 1 shows an IPv6 Header followed by Extension Header.
Allocation
IPv6 addresses are composed of two parts, 64-bit Network Prefix and
64-bit host part. The IPv6 address allocation follows a generally
acceptable assignment policy as shown in figure 1. This allows for an
efficient, hierarchical, and summarizable routing infrastructure.
Easy Address Assignment Methods
IPv6 has three assignment methods
Static
DHCPv6 (Stateful)
Autoconfiguration (Stateless)
An IPv6 host can configure a link-local address for each interface
automatically. By using ICMPv6 router discovery messages, a host can
also determine the addresses of routers, additional addresses, and other
configuration parameters.
Built-in Security
IPSec is built into IPv6 unlike IPv4 in which it is optional. IPSec
requirement is mandatory in IPv6 Protocol Suite Implementation. IPv6
networks have potentially more end-to-end security because of IPSec
availability on all nodes.
Extensibility
New futures for IPv6 can be added through the use of Extension
Headers. At present there are various Extension Headers specified for
QoS, Security, Mobility and Routing purposes.
Mobility
Mobility is built in to IPv6 which allows any node to use Mobile IP. Mobility is achieved using Mobility Extension Headers.
Better Quality of Service Support
IPv6 Header includes a new field called Flow Label that allows
routers to identify and provide special handling for packets that belong
to a particular flow. This field allows for easier identification of
traffic without doing any tricks even when the packet payload is
encrypted with IPSec.
Neighbor Discovery Protocol
Neighbor Discovery Protocol uses ICMPv6 messages to perform various functions such as
Stateless Auto-configuration
Router Discovery
Prefix Discovery
Address Resolution
Neighbor Unreachability Detection
Link MTU Discovery
Duplicate Address Detection
Next Hop Determination
Transition
The transition options supported by IPv6 to transition from IPv4 are
another key feature of the protocol. Many Transitions mechanism are
available for different scenarios. They are mentioned below
Dual-Stack
Tunneling IPv6 over IPv4 networks
Protocol Translation
Within each option are various different techniques to support transition. A few tunneling mechanism are mentioned below
Static GRE Tunnels
6to4 Tunnels
ISATAP
Automatic IPv4-Compatible IPv6 Tunnels
These rich features of IPv6 enable easy deployment, migration and operation of IPv6 networks.
The v and number (4″ or 6″) in IPv4 vs IPv6″ refers to the
related protocol version number. IPv4″ is of course Internet Protocol
version 4″, and IPv6″ is subsequently Internet Protocol version 6″.
IPv4 is of course the older, more supported version of the internet
address procedure. But ultimately, there are no longer any free IPv4
addresses, meaning all of them have been occupied or taken up. What does
this mean exactly?
In a general sense, there will no longer be any alternative IPv4
addresses, directly meaning they will all be occupied and new users will
not be able to venture into cyberspace. Although the realistic
situation is not quite as dire.
Queue in IPv6, the latest Internet Protocol or address procedure. The
older IPv4 only supports a maximum 32 bit internet address, which
translates to 2^32 IP addresses available for assignment (about 4.29
billion total). IPv6 utilizes 128 bit web addresses, allowing a maximum
2^128 available addresses:
340,282,366,920,938,000,000,000,000,000,000,000,000; which if you
couldnt already tell is a very big number.
So basically the IPv4 protocol has run out of available addresses
which is why most websites or internet servers are adopting the newer
IPv6 protocol. In most cases, the two versions are compatible. This
contrast between the two protocol versions is exactly whats being
referred to when IPv4 vs IPv6″ is mentioned.
25 Top Network and IT Industry News Stories of 2011
What big news made a great impression on you in 2011?
Well, 2011, a year full of unforgettable stories, will be remembered for
the death of Steve Jobs, Ciscos refocusing, IPv6′s coming-out party,
Google Executive Go-Round, Android Market Feels Malware Pain and more
2011 could be described as The Year of many
things. The tablet market heated up beyond the Apple iPad. 4G wireless
took off with the emergence of big-time LTE networks. Governments and
hackers screamed for attention by taking down networks, while IPv6
generated interest for giving the Internet a way to carry on.
The shift to cloud computing
sped up. despite hiccups. Data centers took on new looks with the
emergence of fabric switching architectures and a revamped Cisco. And
the shape and faces of the industry changed as IBM, HP, Google and Apple
all announced new leaders, and Microsoft, AT&T and Google made
blockbuster acquisition bids.
Heres a look back at 25 stories that marked huge industry change in 2011.
LTE Everywhere
AT&T at the annual CES conference in Las Vegas formally announced
its plans to launch LTE services during the summer of 2011 and the
carrier followed through. AT&T also announced that it would be
launching around 20 different 4G devices this year, although many
would actually run on its 3G HSPA+ wireless network. Separately, Verizon
at CES showed off 10 LTE devices it would be selling in the first half
of 2011, following its LTE network launch in December of 2010.
Meanwhile, Sprint and Clearwire steadily expanded their WiMAX network
but aired plans for LTE, too. All of this made for more of a
coming-of-age than coming-out party for 4G wireless at the 4G World
event in Chicago during the fall.
Verizon+Apple at Last
Following month after excruciating month of rumors, Verizon and Apple
finally got together in January and announced that the iPhone would be
coming to Verizons network in February. Surveys backed up the notion
that there was much pent up demand for the iPhone on a network other
than AT&Ts, which had been criticized by many for dropping too many
iPhone calls.
The Daily Show host Jon Stewart said the news put an end out our long
national iPhone nightmare. In October, Sprint too began selling the
iPhone. As of November, AT&T still dominated the market for both the
iPhone 4 and 4S.

Google Executive Go-Round
Google announced in January that it was shaking up top management,
with longtime CEO Eric Schmidt becoming executive chairman and
co-founder Larry Page taking hold of the CEO reins all in the name of
streamlining the companys top-level decision making.
Googles performance certainly didnt suffer in the short term from
the move, with the company posting big revenue and earnings increases in
Q3, and the company continued to roll out new offerings, such as social
networking service Google+, a new threat to Facebook. Its hard to
argue that Schmidt, in coming to Google from Novell in 2001, didnt make
one of the greatest career moves in the history of history.
Egypt Shuts Down the Net
Egypts shutdown of the Internet and cell phone networks in an effort
to diffuse protests against the government not only burned free speech
advocates around the world, but it cost the countrys economy at least
$90 million, according to one report. It also raised the specter of an
Internet kill switch being put into the U.S. Presidents hands.
Egypts government wasnt alone in resorting to Internet or cellphone
network shutdowns in 2011, with Libya and Syria among the others
following suit.
The Internet ran out of IPv4 address space in early February when the
Internet Assigned Numbers Authority assigned two of the remaining
blocks of IPv4 addresses each containing 16.7 million addresses to
the Asia Pacific Network Information Centre. This action sparked an
immediate distribution of the remaining five blocks of IPv4 address
space, with one block going to each of the five Regional Internet
Registries.
With IPv4 addresses gone, Internet policy makers ratcheted up the
pressure on network operators to migrate quickly to IPv6, and World IPv6
Day, held in June, showed off the capabilities and readiness of the
Internet Protocol update went off with nary a hitch. World IPv6 Day,
which involved 400 organizations including big name content suppliers,
carriers, hardware vendors and software makers, was said to be the most
watched tech-related event since New Years Eve 1999, when all eyes were
on the Y2K bug.
Nokia Embraces Windows Phone 7
Microsoft and Nokia both have a lot to lose and gain by their
mobile alliance, with the Finnish handset maker deciding to adopt
Windows Phone 7 as its smartphone operating system. Nokia initially said
it wouldnt abandon its own platforms, Symbian and MeeGo, yet though
even MeeGos most ardent backers (Intel, Linux Foundation, Limo
Foundation) wound up taking a new direction with a technology called
Tizen.
As for Windows Phone 7, reports of Microsoft momentum and lack of momentum seemed to alternate as the year went along.
Appleand Steve JobsIntro iPad 2
The next generation of Apples iPad tablet computer is sleeker and
more powerful than the original, and boasts two cameras so that users
can use Apples FaceTime video chat. CEO Steve Jobs surprised the
faithful in February by making the iPad 2 product introduction himself.
The iPad 2 unveiling both excited and frustrated enterprise IT pros.
The product has helped to maintain Apples tablet market lead and was
high on buyer wish lists for the 2011 holiday season, even as a nonstop
stream of competitors some weak, some like Amazons Kindle Fire with
potential flood the market.

HBGary Goes After Anonymousand Loses
Security company HBGary Federal set off an ugly chain of events in
February when CEO Aaron Barr threatened to expose organizers of online
activist group Anonymous, which at that time was focused on defending
Wikileaks, but later in the year branched out to defend numerous causes.
Anonymous taught Barr a hard lesson by breaking into his companys
network, publishing thousands of its emails (including details about
plans to create a new kind of rootkit) and exposing personal data on
Barr.
Barr had initially planned to expose Anonymous at the Security
B-Sides event in San Francisco, but wound up bailing out of that, and
HBGary wound up pulling out of the RSA Conference running at the same
time in San Francisco. Barr did resurface later in the year with a
different security company. Anonymous continued its assault on foes
throughout the year, threatening everyone from Facebook to a Mexican
drug cartel. Anonymous wasnt the only game in town either, with another
group called LulzSec wreaking havoc in late spring/early summer via
websites belonging to the CIA, Sony and others.
Android Market Feels Malware Pain
More than 50 applications containing malware were discovered in
Googles application market in March, a sign that hackers were hard at
work trying to compromise mobile devices running the Android OS. In
fact, it got so bad that Google threw a kill switch to remotely delete
infected Android apps.
As the year went on, security vendors issued reports citing a sharp
rise in mobile malware targeting Android devices, though Google
countered that much of the concern was being raised by security vendors
simply looking to hawk their wares.
RSA at Risk
EMCs RSA Security division shook the industry in March when its
executive chairman announced that a sophisticated cyber-attack on the
company might have compromised its two-factor SecurID tokens. The
advanced persistent threat attack led some observers to call on those
using the tokens for remote access to sensitive information to stop
doing so until RSA clarified the extent of possible compromise.
RSA opened up somewhat about the breach as the year went on,
disclosing it took a $66 million charge to its financial results
associated with coping with the breach. The company said it found two
groups were responsible for the attacks, but declined to identify them.
Earthquake/Tsunami Devastate Japan
Beyond the devastating human tragedy that was the worlds main
concern in the wake of Japans earthquakes and tsunami disaster in
March, the high-tech industry was impacted greatly as well.
Taiwanese semiconductor suppliers faced serious raw materials
shortages from Japan and concerns were raised about Japanese suppliers
to Apple for the iPad 2 as well. Chip plants for Texas Instruments and
others in Japan faced months of disruption and undersea telecom cables
in the Pacific Ocean were damaged.

AT&T Bids for T-Mobile USA
AT&Ts proposed takeover of T-Mobile USA in March would have
created the biggest carrier in the United States, with some 129 million
subscribers. But the union also raised lots of big regulatory,
competitive and customer service questions, with plenty of people
unhappy about the prospects of this deal going down. Among them: The
FCC, which found the proposed $39 billion merger not to be in the public
interest and whose draft order in November convinced AT&T to pull
out of the original deal and take a $4 billion charge against earnings
for ending the original deal.
Meanwhile, carrier consolidation continued via several other deals,
including CenturyLink snapping up Savvis and finalizing its Qwest
buyout, plus Level 3 buying Global Crossing (See also: 2011s top tech
M&A deals)

Amazon Elastic Compute Clouds Bad Stretch
A major outage for Amazons EC2 service in April due to undisclosed
server problems resulted in customers websites being down and/or flakey
for days (even for those who took the precaution of signing on for
multiple availability zones, and raised all the usual concerns about
whether its still too early to trust your business to the cloud due to
shortcomings in failing over such systems.
Amazon, despite being plugged into social network systems such as
blogs and Twitter, was conspicuously quiet about what went wrong,
perhaps due to legal concerns. Amazons network took another hit in
August, though the outage was briefer.
Sony PlayStation Network: Game Off
A major hack of Sonys PlayStation Network knocked the PS3 gaming
community offline for days in April and Sony revealed players personal
information, including credit card numbers, may have been swiped. With
more than 70 million people using the network, some called this breach
one of the worst ever and a possible ID theft bonanza.
The big Interop 2011 show could almost have been called the OpenFlow
show given that it served as one of the first significant exhibitions of
OpenFlow switches and controllers, including those shown off in a lab
at the event. The software-defined networking technology is designed to
enable users to define flows and determine what paths those flows take
through a network, regardless of the underlying hardware.
OpenFlow stems from an open source project borne of a six-year
research collaboration between the University of California at Berkeley
and Stanford University, which hosted the first ever Open Networking
Summit in October to hasten software-defined network development and
further spread the word about the technology. OpenFlow has momentum, but
is far from a sure thing or the only game in town, with heavy hitters
such as Cisco still weighing their options.
Microsoft-Skype $8.5B Blockbuster
Microsofts bold buyout of the voice and video IP company announced
in May is seen by analysts as an aggressive move to challenge Google,
Facebook and others for the hearts, minds and wallets of online users.
Some industry watchers say Microsoft actually had technology in its
portfolio to compete with Skype on many fronts, but that buying the
company gives Microsoft lots of customers fast.
The combination of the Skype buyout and advances on the Windows Phone
7 front also gives Microsoft its strongest mobile offerings to date.
Microsoft has also vowed to integrate Skype with its Lync communications
technology.
Following disappointing financial results to start its fiscal year
2011, Cisco CEO John Chambers this past spring and summer was forced to
acknowledge that the company had been caught off guard by dramatic
changes in its core switching and routing market.
Chambers pointed to lower profit margins as customers switched over to newer Cisco products
like its Nexus line of switches that boast better price/performance
ratios. He said the company needed to make decisions faster and get
leaner and more focused, which translated into hiring a COO, laying off
some 6,500 employees and ditching some of the businesses it had expanded
into, including Flip video cameras.
Microsoft Previews Windows 8; Heads Into the Cloud
While it might seem that weve only begun to know Windows 7, that
Microsoft software has been around now since 2009, so the company has
started cranking up Windows 8 hype. Steve Ballmer kicked off 2011 at CES
in January by announcing Windows 8 would run not just on x86 hardware
but also on ARM processors so common on tablet computers.
Microsoft has further tantalized potential users by demoing boot
times of less than 10 seconds for Windows 8 machines and previewing a
user interface dubbed Metro that borrows heavily from the companys
touch-friendly Windows Phone interface.
Meanwhile, Microsoft is not oblivious to the move by many customers
to the cloud. Microsoft in June debuted its Office 365 cloud service
the companys answer to Google Apps and the latest Microsoft offering
designed to expand the companys reach beyond packaged software.
Microsoft is giving some organizations big incentives to use the new
offering. Office 365 complements earlier Microsoft cloud offerings,
including its Azure platform-as-a-service, which hasnt caught on in a
big way yet. Microsoft said late in the year that Office 365 was proving
to be a big hit, especially with small businesses. (Also see:
Microsoft Office 365 vs. Google Apps for Business)
HP: Out With the Old, In With the New
HP, becoming more focused on software and services under new chief
Leo Apotheker, announced in August it was exploring the sell-off of its
PC market leading Personal Systems Group and shuttering its TouchPad
tablet business just a month after the tablet was launched.
Then in September, HPs board ousted Apotheker after he was on the
job for just a year and brought in Meg Whitman as the new CEO. Whitman
then turned around in October and said HP wasnt ditching its PC
business after all. Meanwhile, HP also announced plans to buy analytics
software company Autonomy for $10 billion.
Googles Big Deal
Google announced in August its biggest acquisition ever, a $12.5
billion deal for Motorola Mobility that turns out to be in large part
about obtaining oodles of patents that can be used to defend the Android
ecosystem against infringement lawsuits and countersue as well.
The deal raised plenty of questions regarding that ecosystem of
partners, however, such as whether Google would now be competing with
phone and tablet makers with its own Droid and Xoom offerings via
Motorola Mobility.
The Apple co-founder who resigned from the company in the mid-1980s
and returned a decade later to make Apple one of the most successful
technology companies in the world died at the age of 56 on Oct. 5.
While Jobs ill health was well known and he stepped down as CEO in
August, the timing of his death was jarring, taking place a day after
Apple introduced the iPhone 4S. Tributes to Jobs poured in from fans,
friends and the famous.
RIM Goes Dark
An outage on Research in Motions BlackBerry network for several days
in mid-October affected millions of customers and gave the company a
huge black eye just as Apple was coming out with its newest iPhone. The
outage brought lawsuits from customers and forced co-CEO Mike Lazaridis
to make a very public apology.
The outage was just the latest in a year of disappointments for RIM
and its customers, as the companys PlayBook tablet met disappointing
reviews and sales have been weak, smartphone releases were delayed and
the company whacked 11% of its workforce.
Rometty Tapped to Lead IBM
IBM announced in October that 30-year veteran of the company Virginia
Ginni Rometty would succeed Sam Palmisano as CEO of IBM in January.
Industry watchers expect a smooth, drama-free transition to Rometty, who
has played a critical role in shaping IBM strategy.
Rometty is currently IBMs senior vice president and group executive
for sales, marketing and strategy. Her promotion, following HPs hiring
of Meg Whitman as CEO, puts women at the top of two of the technology
industrys largest and oldest companies.
Smartphones, Tablets Rush the Enterprise
Many IT shops hemmed and hawed over the years about how to handle
employee-owned devices at work, but 2011 marked the year that many
employees forced employers hands and increasingly, organizations
decided allowing employees to use what they wanted might be a win-win
(See our Network Worlds Hottest Arguments piece on employee vs. corporate owned devices).
A wider variety of devices and useful apps, along with lower prices,
have put smartphones, tablets and other such devices into more peoples
hands (Gartner reported that smartphone sales to end users rose 42% in
Q3 from Q3 last year.). And a batch of new multivendor device management
tools from third-party vendors as well as device makers such as RIM
have made managing heterogeneous mobile environments more feasible and
secure.
Big Data Gets Bigger
Big Data is one of those terms that despite oozing of jargon and hype
did become the real deal in 2011, with major software vendors such as
Oracle and Sybase rolling out Big Data products (in fact, Oracles is
called the Big Data Appliance) and big name investors like Accel
Partners putting its money behind the concept, in the form a $100
million Big Data Fund for startups.
Big Data refers generally to the gobs of information generated by Web
sites, social networks, sensors and other sources apart from
traditional enterprise applications and that can be put to use for
diverse business purposes if organized and analyzed in a sophisticated
way. Gartner even added Big Data to its 2011 Hype Cycle for Emerging
Technologies, along with gamification and Internet of things, and shows
Big Data still has a way to go before it hits the Peak of Inflated
Expectations.
