Twitter, a very attractive website, offers a social networking and microblogging service, enabling its users to send and read messages called tweets. Tweets are text-based posts of up to 140 characters displayed on the user's profile page.
I knew twitter long ago, but I haven’t joint it until so many people play with it today. When my fiends talked twitter with me, celebrities, movies, entertainment, gossip, etc. I think that it is so fantastic to chat and share interesting and exciting things and experience on twitter. No matter who you are, just join it and share something, new world will be opened in front of you.
After I joined twitter, I feel that it gives me a new horizon, such as history, military, politics, literature, philosophy, technology, etc. so many professional people in the different fields can offer you enough info to help you know the world’s every aspect.
Some people usually like to ask each other: “Can you live today without twitter?” Oh, no, it’s hard to imagine the life without twitter. If you are a twitter fan, you know it.
Someone define “without twitter, the world will be like this” as the following drawing:
I am an editor, I deeply feel that to chat and share ideas with friends by tweeting are so important to me. Indeed, I can get some inspiration from someone’s twitter; for example, I need to find some news and details about Cisco, Cisco network product like Cisco router, Cisco switch, Firewall security, etc. When I have no idea about that, I can use twitter to find some friends who are experts of Cisco and Cisco networking equipment, to ask them about the Cisco’s details: Cisco is for what; what are router and switch used for; Do we need them in our daily life; how to use it. So no matter you are a personal, a group, or an enterprise, twitter is so necessary for you to connect you to outside world and others. Now, “Twitter or not today!” is becoming a fashion around us.

Cisco provides legendary interoperability, providing real assurance that your investment in Cisco gear is ready for whatever tomorrow brings.
Enterprise Class Features
Depends on the router capabilities and the IOS image you have, you can have an enterprise class features in your LAN. Advance firewall system, Intrusion Detection System, Multicast handling, VoIP, all of that you can have just by upgrading your Cisco routers later when your company got bigger.
Compared with other manufacturers, Cisco suppliers often provide a very competitive price of Cisco network equipment. New, refurbished and used Cisco routers, switches, firewall security, and so on, all different Cisco items are offered on the market for you to choose. If you want to save money, used and refurbished Cisco network products is not a bad choice.
Nowadays, business requires a network platform that enables technology innovation and business-critical services across the entire network. Cisco has ability to provide an end-to-end network platform tied together by a common infrastructure and a common operating system, and manageable as a single, cohesive entity. Why choose Cisco? That’s it.
Cisco is never giving up innovation, so it is always upgrading its core technology to bring more professional networking solutions and better network services to our CISCO users and enterprise. Recently, exactly, June, 2011, to help service providers meet the rising tide of traffic generated and to help businesses make the transition to IPv6, Cisco’s newly released Visual Networking Index Forecast (VNI) marks the beginning of what the company calls the "Zettabyte Era," and its new ASR 9000 Series aggregation-services routers.
The new Cisco ASR 9000 system consists of the new Cisco ASR 9922 Router and high-density 10G and 100G interfaces for the network edge and the Cisco ASR 9000v for the network aggregation layer, as well as the existing Cisco ASR 9010 and Cisco ASR 9006 Routers.
Cisco on June 7 also introduced a new innovation called nV (network virtualization) technology, which was created to make network management easier and grow capacity by collapsing the network edge, aggregation and access layers into a single ASR 9000 system.
According to Cisco officials, the new ASR 9000 system combined with the nV technology offers 36 times the capacity of other competing products at 96 terabits per second. With such capacity, users could stream recordings of all Super Bowls, World Cup and Cricket World Cup matches in less than a second, or download 180,000 DVDs every minute, the vendor said.
The combination also means operating cost savings of up to 70 percent compared with competing edge platforms, simplified IPv6 transition and support for Cisco’s Videoscape technology.
More Facts about the ASR 9000 system:
Network simplification and savings are achieved through plug-and-play capabilities, singular point-of-service management using Cisco Prime for Internet Protocol Next-Generation Network (IP NGN), cost-effective configurations and ease-of-deployment features. This capability is available to the more than 500 existing Cisco ASR 9000 customers via an upgrade.
Cisco Videoscape technology is supported with the Cisco Integrated Service Module for caching, streaming and monitoring to optimize and monetize the video experience.
From Official Cisco
The Cisco ASR 9000 Series can be positioned for the following applications:
Residential any-play services, including cable, DSL, Passive Optical Network (PON), and Ethernet to the X (ETTx)
Business Layer 2 VPN and Layer 3 VPN services
Video service-delivery networks
According to Cisco, the ASR 9000v product is available now, with the ASR 9922 becoming available early next year. But existing customers won’t have to deploy all new gear to take advantage of Cisco’s new virtualization technology. Cisco says the 500 operators who have already bought ASR 9000 gear will be able to introduce the intelligence with a simple upgrade.
The company already has several customers for the technology, including China Telecom, Cox Communications, Comcast and FastWeb. Verizon Wireless also uses Cisco's ASR 9000 routers.
Cisco has unleashed a world of hurt on its shareholders, masquerading as a consumer company that sells Flip phones, Umi telepresence, and Linksys routers. There's nothing wrong with selling gadgets to consumers. Apple does it brilliantly, and profitably. But Cisco isn't Apple.
In a sense, Apple might be a place where Cisco can find comfort in its time of trouble. People forget how screwed up Apple was in the 90s. The fact that Apple turned it around can provide a ray of hope to Cisco shareholders and the company's beleaguered CEO, John Chambers. If Chambers can keep his job.
Server and PC marker Dell has also had its share of problems in recent years – accounting scandals, poor sales execution, and exploding products – but of late, it has been on the upswing. It has had some success building custom servers for hyper scale data centers. It bought its way into the storage racket proper instead of just reselling other companies' kit (LSI and EMC, mainly). And it moved into services with its Perot Systems acquisition.
The rub is that Dell's networking business is no more real than its storage business used to be. It is merely rebranding kit from Brocade and others. Until Dell fixes that, it will not be a credible infrastructure stack player.
Meanwhile, Cisco has done a remarkable job building a server business out of nothing with its "California" Unified Computing System blade and rack servers – and with a fair amount of actual engineering – but it is not a profitable volume manufacturer any more than IBM was. Big Blue couldn't cut it in printers, memory, disk drives, and PCs, and Cisco is having trouble with anything other than core switches and routers.
One could argue that Cisco should not have entered the server market at all, but that is an over-simplified view. No doubt, the move into servers has not only annoyed Cisco's former partners in the server business, but compelled them to start selling their own networking products, either rebadged (from Brocade, Juniper, or Blade Network Technologies) or built with the help of ODMs (Sun and now Oracle does this, and so does Dell).
More about Cisco Switching Business
What is hurting Cisco's switching business? Mellanox, Juniper, Brocade, Extreme Networks, Arista Networks, and IBM can make faster and lower-cost top-of-rack switches, and there are cheaper alternatives to Cisco's end-of-row plain-vanilla Catalyst 6000 and converged Nexus 7000 switches.
Chambers (Cisco’s CEO) may believe that the price/performance of the Nexus 7000 compared to earlier Catalyst products is what is driving Cisco's switching biz down. But it is probably more accurate to say that Cisco's prices are too high relative to the competition.
Even though competitors shared a certain market, Cisco is still proud of its core offer and service. Every CISCO user knows that what Cisco attract him to choose it.
Related: Cisco owns a large number of popular Cisco switches among enterprise users. To serve enterprise better, Cisco instantly improve its service and networking solution. Now, let’s check some star Cisco switches: Cisco 2960, Cisco 3560, Cisco 3750, and Cisco 4500…which type you prefer to?
As buddies, CISCO and Xerox will ally to bring more managed print services, mobile print services and cloud IT outsourcing to solution providers, particularly to Cisco partners who haven’t delved into managed print arena, said executives.
“Xerox and Cisco think networking and print managed services are a great combination. They’re like peanut butter and jelly,” said Rick Dastin, president of Xerox Enterprise Business Group. “And it tastes good too.”
The solutions CISCO and Xerox offered will benefit customers as the list below.
A. Xerox Managed Print Services (MPS) over Cisco Borderless Networks: The partners mean to consolidate IT and print management using the network's embedded security, WAN optimization and Internetwork Operating System (IOS) software. It will monitor print technology and supposedly reduce operating costs, protect confidential data from any location, and improve employee productivity with advanced mobile and cloud printing applications.
B. Xerox Cloud ITO Services built on Cisco's UCS and Vblock infrastructure: It will accelerate customer rollout of new IT services, so they can respond better to changing needs of the workforce and reduce IT costs through a private, public or hybrid cloud environment. These infrastructure-as-a-service and cloud consulting services as well as private cloud deployments will come from ACS, a Xerox company.
C. Xerox Mobile Print Solution on Cisco virtual desktop clients and its Cius tablet: Mobile workers will be able to print from any e-mail-enabled device including Cisco's virtual desktops clients and Cius tablets to any enabled printer using Cisco Borderless Networks and Wireless LAN solutions from any location.
As we known, Cisco has many partners, such as famous Dell and Microsoft; they also have some items to be buddies. What surprise will Cisco bring to Cisco users and customers; we are looking forward to it.

NetBase Solutions, a SOCIAL MEDIA ANALYTICAL COMPANY, delivered a report recently, showing that Cisco is more popular than other Silicon Valley enterprises, just followed the Salesforce.com.
This report may make Cisco confident of recovering from difficulties while Cisco is surrounded by bad news for its terrible performance.
Why did Cisco can regain too much applause from social networks? From what customers really care about; maybe we can get the answer. Even though Cisco shut down flip video camera business, will eliminate up to 4000 jobs in the near future, didn’t get support from investors, it is still a minion in social Medias. More important is that most Cisco users are satisfied with its network equipment, especially routers, switches and firewall security for family and enterprises.
Actually, Cisco and Salesforce.com have been partners for several years, working together to help you join online conversations about your company and take control of the customer experience in Web channels outside your company’s domain. The typical project between Cisco and Salesforce.com is to combine Salesforce.com's Service Cloud 2 and Cisco's Unified Communications to deliver a complete cloud computing solution for customer service. The solution empowers small and medium sized companies to run their customer service completely in the cloud. They share a vision about moving technology into the cloud and leveraging social networking sites like Facebook, Twitter and Google to deliver services to their customers where they are already collaborating.
Because of increasing popularity of talking and sharing anything with each other on internet, more and more enterprises and groups are willing to make full use of the social media service to enlarge their business, intensify market competition to meet challenges from counterparts and other related markets.
Although Cisco faces a big challenge from consumer market as well as enterprise market, it still keeps its own superiority, providing high quality Cisco routers and switches for SOHO, small, medium and large enterprises, better services for consumers. Now Cisco is actively learning how to innovate faster and delight its clients through a radically different approach to management, which will make its prospects bright.
What’s 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.
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 as IP data, Converged voice and data, Security and VPN. More info visit White Paper: Cisco IOS and NX-OS Software Reference Guide
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:
interface vlan 1
ip address w.x.y.z 255.255.255.0
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
copy tftp flash
Cisco IOS Download Tips
Generally, if you want to download or upgrade Cisco IOS while having a used Cisco router or didn’t 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.)

Many electronic stars promote their tablets one after the other while iPad is sweeping over the world, such as Samsung’s Galaxy Tab, Lenovo’s LePad, Acer’s Iconia Tab and so forth. To follow this fashion and share market with other competitors, CISCO also announced that it would bring Cisco’s Cius Android tablet to AT&T in the following fall. Cisco Cius, Android-based, business-aimed, is a “mobile collaboration tablet that delivers virtual desktop integration with anywhere, anytime access to the full range of Cisco collaboration and communication applications, including HD video.”(John Chambers, Cisco CEO)
Also to aim at business sect, the Cius doesn’t appear to be a consumer product. It’s compatible with Cisco’s suite of business software tools, and designed to be able to connect mobile employees with the right people and right content from within the network. To our surprise, CISCO’s Cius is fully interoperable with telepresence tools, offers HD video streaming, multi-party conferencing, email, messaging, browsing and the ability to produce, edit and share content stored either locally or on the cloud.
And it features a front-mounted 720p HD camera that refreshes at up to 30 frames per second; Wi-Fi-enabled, comes with an accelerometer, has a detachable battery and a 5-megapixel rear-facing camera.
Cisco first unveiled the Cius tablet last summer. At the time, the company said the device would sell for less than $1,000. However, Cisco has yet to reveal pricing for the tablet. AT&T also failed to say how much it will charge for access to its HSPA+ network from the device.
Now, AT&T announced that it will sell CISCO’s Cius to enterprise users this fall. Cisco is shifting away from the consumer market. Besides the business-focused tablet---th Cius, the typical example is that Cisco killed off Flip video camera business and refocused its operation on core routing (all types of Cisco enterprise-based routers: Cisco1800/1900/2800/2900 series, etc., switching (Cisco switch catalyst 2960/3560/3750, 4500 series, etc.) and services, collaboration, architectures, and video.
No matter what difficulties Cisco need to face, we still believe that Cisco is a leader in networking solution, services for enterprises.
What Cisco brings to us next like surprising Cius? We are looking forward to it.
Recently, when you open internet to search news related to Cisco, title keywords like reorganize, recover, return, regain and refocus are common seen among Cisco news. Owing to increasing competitors such as Netgear, Juniper, Huawei, etc. all these have their own advantages, and share certain market with Cisco. So for Cisco’s part, there is a very fierce competition between itself and others. Moreover, there are many facts that show Cisco facing a big challenge, for example, Cisco has lost share in recent years in routers, and shut down its Flip video camera division in order to refocus on its core capability of router and switch.
Deciding to share enterprise market with Cisco, Huawei, Technologies Co., China’s largest telephone-network equipment maker, is expanding beyond its traditional business of supplying equipment for phone networks as it strives to more than triple sales to $100 billion in the next 10 years. The push to win more orders from businesses and government agencies may pose its biggest threat to Cisco. And Cisco now is actively searching for partners to enhance its competitive power, such as cooperating with Xerox to offer print services via the cloud through Cisco’s data center technology. HP, another challenger for Cisco, has introduced products supporting a new architecture namely FlexNetwork, which is directly targeting the Cisco's Borderless Networks strategy.
Meanwhile, Cisco also pays attention to their inner management to improve its efficiency while solving problems. Although Cisco has lost its Flip focus, faced more competition, it still has big predominance in routers, switches and service for business and enterprise. Cisco still retains 70% or so of the total switch market. And enterprise and business are Cisco’s main target market.
As we known, Cisco owns many types of routers and switches aim at providing the most professional service for small to large enterprise, such as popular series Cisco 1800 series, 1900 series, new items like Cisco 2911; Cisco switches series like switches 2960, 3560 series…
Frankly, even though Cisco faces many challenges from its counterpart, its core service is still competitive. Of cause, refocusing on its core, concentrate business and enterprise, all these actions can help Cisco keep a good condition among international market.
Which of the following is a reason why IPv6 has been developed?
a. IPv4 addresses are not secure. / b. IPv4 addresses are running out. / c. Dynamic address allocation is desired. / d. Mobile IP networking is needed.
What version of IOS do I need to run on a Cisco 3550 and 3560 to support IPv6?
Which routers are IPv6 enabled? Can anybody suggest me any IPv6 enabled routers?
Have you ever come to similar problems? With more netizen and faster development of internet, mobile internet, more and more people require a better enjoyment of surfing on the net and a higher internet security, we usually like to compare IPv4 with IPv6, often ask others that what IPv6 will bring to us?...
IPv6, a version of the Internet Protocol (IP), is designed to succeed Internet Protocol version 4 (IPv4). The Internet's growth has created a need for more addresses than IPv4 is capable of. IPv6 allows for vastly more numerical addresses, but switching from IPv4 to IPv6 may be a difficult process.
Comparison to IPv4
Pv6 specifies a new packet format, designed to minimize packet header processing by routers.
Advantages comparing to IPv4
Larger address space: The most important feature of IPv6 is a much larger address space than in IPv4. The length of an IPv6 address is 128 bits, but 32 bits in IPv4.
Multicasting: Multicasting (the transmission of a packet to multiple destinations in a single send operation) is part of the base specification in IPv6. In IPv4 this is an optional although commonly implemented feature.
Stateless address auto configuration (SLAAC): The packet header in IPv6 is simpler than that used in IPv4. IPv6 routers do not perform fragmentation…
Mobility: IPv6 routers may also support network mobility which allows entire subnets to move to a new router connection point without renumbering.
More advantages…such as options extensibility, jumbo grams.
