According to networking giant Cisco Systems, the amount of Internet traffic worldwide will quadruple by 2015, driven by the explosion in the number of connected devices and connected people, the amount of video and faster broadband speeds. By 2015, network traffic will have quadrupled to 966 exabytes per year as a content hungry populace gains access to cyberspace on more than 15 billion network connected devices that, ironically enough, will outnumber people 2 to 1.
The projected increase of Internet traffic between 2014 and 2015 alone is 200 exabytes, which is greater than the total amount of Internet Protocol traffic generated globally in 2010. On the verge of reaching 1 zettabyte, which is equal to a sextillion bytes, or a trillion gigabytes by 2015, global IP traffic growth is driven by four primary factors, according to Cisco.
The proliferation of tablets, mobile phones, connected appliances and other smart machines is driving up the demand for connectivity, it said.
"The explosive growth in Internet data traffic, especially video, creates an opportunity in the years ahead for optimizing and monetizing visual, virtual and mobile Internet experiences. As architect of the next-generation Internet, Cisco stands ready to help our customers not only accommodate this rapid expansion of Internet activity through the evolution of their networks but also help them thrive as a result of it," said Suraj Shetty, vice president of worldwide service provider marketing, Cisco.
While not addressed in Cisco's report, the numbers are further cause for concern for arbitrary data caps with overage fees. According to Cisco, the average fixed broadband speed in 2015 will reach 28Mbps, up from 7Mbps in 2010.
Service providers also will have to deal with the blurring of the line between fixed and mobile traffic, as consumers increasingly expect to have the same experience on their mobile devices as they do on their PCs or connected televisions.
The same warnings are there for networking vendors, including Cisco, Webster said. They need to build technology that not only increases capacity and scalability, but also is more intelligent.
By projecting accelerated internet adoption, Cisco is implying associated growth in many other fields. How many industries are required to fuel telecommunications growth and how many are in turn impacted by it? It’s quite possible that Cisco VNI isn’t a vision for the future of internet traffic, but a vision of technology as a whole. If something as central as online activity is going to grow exponentially, then maybe the entirety of science and technology will come along for the ride.

Today, for business, satisfying and attracting customers is indispensable. That’s because customer requires better service and multifunctional products. Yet to meet customer’s need poses challenges. And the competition between counterparts is fierce. Because my work is related to Cisco, so I’d like to take Cisco as an example to analyze Cisco and its competitor Juniper.
Cisco was founded in 1984 and quickly became dominant. In its acquisitions, it focused on integrating marketing functions, not integrating the technology that it acquired. Cisco’s approach is based on multiple hardware boxes. Each hardware box runs proprietary software, and a different chip. For customers that has created huge complexity.
Juniper founded in 1996, the first serious challenge to Cisco. Jim Duffy notes in Network World that with the growing importance of the Internet, venture capitalists and unhappy Cisco customers invested a start-up in order to build a better mousetrap, specifically for service providers. Juniper’s first year was nurtured with early investments from the AT&T, Ericsson, Lucent, Nortel, Siemens/New bridge Networks, 3Com and UUNET. IBM agreed to develop custom chips for Juniper’s Internet routers.
Network Router Showdown: Cisco vs. Juniper
Cisco does have competitors, especially in sectors that crave speed. For example, when service providers like MCI/WorldCom, Sprint or AT&T update their infrastructure, they increasingly are choosing to buy from Cisco rival Juniper Networks (Nasdaq: JNPR). In fact, Liscom said, 23 of the 25 major service providers now use Juniper routers.
Juniper routers increasingly are being used in the infrastructures of governments' and financial institutions' intranets. According to her, Juniper boxes are purpose-built to handle new services, such as VPNs (Virtual Private Networks) that are tunneled over existing IP networks.
Operationally, both Cisco and Juniper routers are based on different hardware and software concepts. Cisco routers use Cisco IOS and Juniper routers use JUNOS.
Applications wise, both Cisco and Juniper cater to similar market segments. However, both have some advantages in certain areas compared to the other. Cisco, being the first to enter the market, has better market penetration. One of the strong areas of Cisco is the low-end router market including remote-office, and branch-office connectivity solutions. Both Cisco and Juniper provide high-end router solutions that offer gigabit transfers and advanced security routing solutions.
Cisco vs. Juniper, Tragedy or Comedy
From the analysis above we know that in fact both Cisco and Juniper have its own advantages in the market. The research and targeted consumer are little different, they share different markets. No winner, just comedy.

There are several types of routers you may hear of: wired router, wireless router.
More detailed classification: Internal router (IR): All interfaces belong to the same area; Area Border router (ABR): Interfaces to multiple areas; Backbone router (BR): Interfaces to backbone; Autonomous system boundary router (ASBR): Exchange routing info with other autonomous systems; Designated router (DR): Generates link-state info about the subnet; Backup designated router (BDR): Becomes DR if DR fails.
If you use computers in your home or office, it is likely that your computer is connected with other computers through some type of router. Like a police officer directing traffic at an interchange, a router will direct or route information, data and files to the locations they need to go. Generally, Routers that we used can either be wired or wireless.
A wired router will generally connect to your computer and computers or hardware through an Ethernet cable. This happens with the use of output ports. And the only input port provided on a router will be used for the Internet.
A wireless router may allow access from several computers through wired Ethernet cables and through wireless connections. You will know the router you are using is wireless if it comes with an antenna. The antenna will provide the router with a specific range that allows other computers in the area with wireless capabilities to access the router, provided they have password access.
Two Typical Routers We Usually Used
If you have ever been to a coffee shop or hotel that offers Wi-Fi access, chances are they are using a commercial-grade router. These routers are much more powerful than what you would purchase at your local electronics or computer store. The best commercial routers will be able to provide access to the Internet, files and printing, for example, with little problem. Commercial routers may also be used by businesses, hospitals or in a university setting as part of a wide area network or WAN. (Cisco is a leading router manufacturer to aim to provide router and networking solution to small, medium and large enterprises) This is a network that allows computers to connect to each other even if they are in another building across town. The commercial-grade router will be used to connect with the wide area network (WAN) on one side and a smaller network called a local area network (LAN) on the other. The local area network may consist of one large office within a building. In that case, you could have multiple LANs connecting to the WAN through one or multiple routers.
If you are looking for a router for your home or small business, you likely can find what you need at your local electronics store. Generally you will want a router that serves as a wireless access point (WAP). It should also be a network switch. The wireless access point (WAP) basically provides the wireless access that everyone wants. That wireless access can be both to the Internet and to other computers in the home or office. Routers that come with a network switch tend to be faster and provide more evenly distributed bandwidth to each port. Consumer routers will come in a variety of price ranges and strengths. Some of the lower priced consumer routers will not have a very strong firewall. (Cisco Linksys E-series routers, powerful home routers, are welcomed by a lot of Cisco fans, more info of Cisco’ home product store you can visit Cisco’s official site: cisco.com).
Internet colors and changes the world by broadening our horizon and connecting people around the world together.
Referring to network, some networking devices and equipments you must know. These are router switch and hub, which are all computer networking devices that let you connect one or more computers to other computers, net to other nets. Each has two or more connectors called ports into which you plug in the cables to make the connection.
How are data transfer and the implementation of networking protocols made possible in this powerful network? It is made possible because of networking devices that regulate data traffic over the whole network, providing connectivity and control. It is made possible because of networking devices that regulate data traffic over the whole network, providing connectivity and control. The network design is based on the OSI (Open Systems Interconnection) model.
After getting the general knowledge of router, switch and hub, you may are confused with these three devices. If they are all networking equiments that act as mediators at various levels of this networking model. What is the difference among them? Let’s do that and check it out.
The first is router, which connect two or more computing networks together. It is a highly intelligent device with embedded software that are used to control the flow of data packets across diverse networks, and charged with the responsibility of controlling the inter network data traffic.
A switch is charged with the job of connecting smaller segments of a single network into a connected whole. They are extensively used in Ethernet local area networks.
The last one, hub, connecting various Ethernet devices to integrate them into a whole network segment. It is one of the most basic hardware devices that connect two or more Ethernet terminals in a network.
More features of router, switch and hub
Router: Functional on the network layer of the OSI model, and it is also known as level 3. They integrate logical subnet together and their operation is made possible by inbuilt operating systems. They are designed to calculate the best possible path for transmission of data packets between networks. The basis for routing of data through a router is the use of Internet protocol addresses.
Switch is functional on the layer 2 of the OSI model. This layer is often referred to as the data link layer. Network switches transfer data across a network segment using MAC addresses for reference.
A hub operates only at layer 1 level of OSI model, which is the physical layer. Integrating Ethernet terminals together is its only function and it is a passive device used for data transfer.
Among these three networking devices, hub is gradually less used, and the most popular today is router. How much you get from this analysis?
If you need a router or switch, the following table of comparison between router and switch make you clearer.
More expensive than hubs or switches
Costlier than hubs
Cisco, Juniper Networks, Belkin, Extreme Networks, Huawei, Netgear
Cisco, Sun Systems, Oracle, Belkin, Linksys, and Net Gear, Huawei
Routers connect two or more logical subnets, which do not necessarily map 1-1 to the physical interfaces of the router.
Network switches inspect data packets as they are received, determining the source and destination device of that packet, and forwarding it appropriately
A router is a piece of hardware tailored to the tasks of routing and forwarding information. Routers generally contain a specialized operating system, RAM, NVRAM, flash memory, and one or more processors, as well as two or more network interfaces.
A way of routing electricity and data flow patterns through circuits based on binary decisions
Routers operate at Layer 3 (Network) of the OSI model.
Network switches operate at layer two (Data Link Layer) of the OSI model.
Rate of Collision:
Switch having a connection that can carry both transmitted and received signals at the same time that we know this as a full-duplex communications. This will reduce or minimizes the possibility of collisions.
It’s not a secret for all that Cisco is restructuring its consumer market, including giving up flip video camera business, bracing for its biggest layoffs, refocusing on Cisco’s core networking, integratng Cisco umi into the company's Business TelePresence product line, assessing core video technology integration of Cisco's Eos media solutions business….
Also Cisco claimed that it would exit aspects of its consumer businesses and realign the remaining consumer business to support four of its five key company priorities – core routing, switching and services; collaboration; architectures; and video. As to this innovative and constructive programs, John Chambers, Cisco chairman and CEO, explains that Cisco‘s key, targeted moves in support of its network-centric platform strategy will help Cisco and its service provider customers optimize and expand their offerings for consumers, and help ensure the network's ability to deliver on those offerings.
Well, more benefits or more disadvantages Cisco refocus on its core technology, which means that it will provide better networking solutions and services for its target enterprises, have more potential partners to realize its projects. Just like losing weight, Cisco is cut down its consumer business that seems not bring better profits and improve its core technology. So for this aspect, it’s not bad news for Cisco and enterprise. And for personal consumer, although it cannot enjoy the further surprise by upgrading flip video camera, they also can get more advantages from networking innovation.
Who will benefit more or more disbennifit? Less or more? It depends on whether those restructuring measures become effective or bring practical effects? Let’s looking forward to it!

With the fast development of internet, People hope to enjoy internet service everywhere, anytime and by every way. So mobile internet has come after the internet. If you are a net user, you should be familiar with routers, or desktop boxes used to provide connectivity between PCs, laptops and printers in a home or small office.
To help people better to enjoy the surprise, service, different news and things. Cisco, as the worldwide leader in networking that transforms how people connect, communicate and collaborate, announced a new super router called Cisco CRS-3 Carrier Routing System. It was designed for to serve as the foundation of the next-generation Internet and set the pace for the astonishing growth of video transmission, mobile devices and new online services through this decade and beyond.
With more than 12 times the traffic capacity of the nearest competing system, the Cisco CRS-3 can deliver up to 322 tbps of capacity, more than tripling the 92 tbps capacity of the Cisco CRS-1, and it is able to stream every film ever made, from Hollywood to Bombay in under four minutes. Fantastic, that means many things can be realized with coming of Cisco CRS-3 Carrier Routing System, for example, Americans can download all the books in the library of Congress in one second; 1.3 billion Chinese people can call simultaneously each other by video phones.
More Highlights and Capabilities of the Cisco CRS-3
The new Cisco Data Center Services System provides tight linkages between the Cisco CRS-3, Cisco Nexus family and Cisco Unified Computing System (UCS) to enable unified service delivery of cloud services. This intelligence also includes carrier-grade IPv6 (CGv6) and core IP/MPLS technologies that permit new IP NGN architectural efficiencies required to keep pace with the rapidly growing cloud services market.
The Cisco CRS-3 offers dramatic operational expense savings and up to 60 percent savings on power consumption compared to competitive platforms.
The new Cisco router, the Cisco CRS-3 Carrier Routing System is powered by the new Cisco Quantum Flow Array Processor, which unifies the combined power of six chips to work as one, enabling unprecedented levels of service capabilities and processing power.
Attention here: the Cisco CRS-3 is currently in field trials, and its pricing starts at $90,000 U.S. Wow, so expensive, hardly to afford it, friends, are you ready to accept it?

When someone talk about Cisco router, or Cisco switch with me, I’m very confused about this. Router? Switch? What are they? What are they used for? Oh, My Lady Gaga, complicated.
However, after I have found some details of router and switch, it seems a little interesting. Because both router and switch are tightly related to network, to internet. If you have PCs, if you need to email to somebody, or if you want to chat with friends, they are necessarily contained. Haha, eager to get more information of router and switch. I search many details and “the difference between router and switch” through Google. Now, I’d like share some key info about router and switch.
What’s a router? A router is a more sophisticated network device than either a switch or a hub. It is a device that forwards data packets across computer networks, and perform the data "traffic directing" functions on the Internet. On the Internet or on a large corporate network, for example, routers serve as intermediate destinations for network traffic. These routers receive TCP/IP packets, look inside each packet to identify the source and target IP addresses, then forward these packets as needed to ensure the data reaches its final destination. Routers for home networks (often called broadband routers) also can join multiple networks. These routers are designed specifically to join the home (LAN) to the Internet (WAN) for the purpose of Internet connection sharing. In contrast, neither hubs nor switches are capable of joining multiple networks or sharing an Internet connection.
And switch? A network switch or switching hub is a computer networking device that connects network segments. The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. By paying attention to the traffic that comes across it, it can "learn" where particular addresses are. For example, if it sees traffic from machine A coming in on port 2, it now knows that machine A is connected to that port and that traffic to machine A needs to only be sent to that port and not any of the others.
The two pieces of equipment (router and switch) look so similar and perform some similar functions, but each has its own distinct function to perform on a network. To be simple, switches create a network. Routers connect networks. A router links computers to the Internet, so users can share the connection. A router acts as a dispatcher, choosing the best path for information to travel so it's received quickly.
So what do you need? A router or switch? After got these above, you can make sure that which you need. And more information of Cisco sale, you can visit RouterSwitch.com.
The Cisco ASA 5505 Firewall is the smallest model in the new 5500 Cisco series of hardware appliances. Although this model is suitable for small businesses, branch offices or even home use, its firewall security capabilities are the same as the biggest models like 5510, 5520, 5540, etc.
The Adaptive Security technology of the ASA firewalls offers solid and reliable firewall protection, advanced application aware security, denial of service attack protection and much more. Moreover, the performance of the ASA 5505 appliance supports 150Mbps firewall throughput and 4000 firewall connections per second, which is more than enough for small networks.
The difference of the 5505 model from the bigger ASA models is that it has an 8-port 10/100 switch which acts as Layer 2 only. That is, you cannot configure the physical ports as Layer 3 ports, rather you have to create interface VlANs and assign the Layer 2 interfaces in each VLAN.
By default, interface Ethernet0/0 is assigned to VLAN 2 and its the outside interface (the one which connects to the Internet), and the other 7 interfaces (Ethernet0/1 to 0/7) are assigned by default to VLAN 1 and are used for connecting to the internal network.
Basic Steps to Configure Cisco ASA 5505:
Step1: Configure the internal interface vlan
ASA5505 (config)# interface Vlan 1
ASA5505 (config-if)# nameif inside
ASA5505 (config-if)# security-level 100
ASA5505 (config-if)# ip address 192.168.1.1 255.255.255.0
ASA5505 (config-if)# no shut
Step 2: Configure the external interface vlan (connected to Internet)
ASA5505 (config)# interface Vlan 2
ASA5505 (config-if)# nameif outside
ASA5505 (config-if)# security-level 0
ASA5505 (config-if)# ip address 18.104.22.168 255.255.255.0
ASA5505 (config-if)# no shut
Step 3: Assign Ethernet 0/0 to Vlan 2
ASA5505 (config)# interface Ethernet0/0
ASA5505 (config-if)# switchport access vlan 2
ASA5505 (config-if)# no shut
Step 4: Enable the rest interfaces with no shut
ASA5505 (config)# interface Ethernet0/1
ASA5505 (config-if)# no shut
Do the same for Ethernet0/1 to 0/7.
Step 5: Configure PAT on the outside interface
ASA5505 (config)# global (outside) 1 interface
ASA5505 (config)# nat (inside) 1 0.0.0.0 0.0.0.0
PS: PDATE for ASA Version 8.3
From March 2010, Cisco announced the new Cisco ASA software version 8.3. This version introduced several important configuration changes, especially on the NAT/PAT mechanism. The “global” command is no longer supported. NAT (static and dynamic) and PAT are configured under network objects. The PAT configuration below is for ASA 8.3 and later:
object network obj_any
subnet 0.0.0.0 0.0.0.0
nat (inside, outside) dynamic interface
Step 6: Configure default route towards the ISP (assume default gateway is 22.214.171.124)
ASA5505 (config)# route outside 0.0.0.0 0.0.0.0 126.96.36.199 1
The above steps are the absolutely necessary steps you need to configure for making the appliance operational. Of course there are much more configuration details that you need to implement in order to enhance the security and functionality of your appliance, such as Access Control Lists, Static NAT, DHCP, DMZ zones, authentication etc.
