Demands on IT infrastructure are changing. Improving network efficiency and articulating the clear value network infrastructure brings to your business have never been more important. The Cisco Catalyst 3560-E Series access and aggregation switches offer networking solutions that can expand with your business without costly upgrades or network disruptions, maximize your network investment, and decrease network costs over time.
Increased desktop bandwidth, expanded use of real-time communication and collaboration applications, and the desire to maximize networking investments are changing the way network solutions are designed and implemented. Supporting Gigabit Ethernet to the desktop often requires 10 Gigabit Ethernet connections between the access and aggregation layers to be able to maintain a quality experience for users.
These deployments can sometimes face space constraints. Voice-over-IP (VoIP) phones, security cameras, and other devices are requiring Power over Ethernet (PoE) support in networking devices. Purchasing a network solution today that grows with your business and network needs can help ensure your company’s competitiveness and success for tomorrow.
10 Gigabit Ethernet Uplinks and the Cisco TwinGig Small Form-Factor Pluggable Converter
The Cisco Catalyst 3560-E features wire-speed 10 Gigabit Ethernet uplink ports for high-bandwidth applications, relieving congestion and helping ensure smooth delivery of data. The TwinGig converter (see Figure 2) converts a 10 Gigabit Ethernet X2 interface into two Gigabit Ethernet Small Form-Factor Pluggable (SFP) ports.
Power over Ethernet
The Cisco Catalyst 3560-E Series can provide a lower total cost of ownership for deployments that incorporate Cisco IP phones, Cisco Aironet wireless LAN (WLAN) access points, or any IEEE 802.3af-compliant end device. PoE removes the need for wall power to each PoE-enabled device and eliminates the cost for additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments. With the introduction of Enhanced Power over Ethernet the 3560-E Series can scale beyond 15.4W per port delivering maximum solution simplicity for 802.11n access point deployments.
Redundant Power System
The Cisco Catalyst 3560-E Series Switches support the Cisco Redundant Power System 2300 (Cisco RPS 2300). The Cisco RPS 2300 (Figure 3) increases availability in a converged data, voice, and video network by providing transparent power backup to two of six attached Cisco Catalyst 3560-E switches at the same time. A power supply can be replaced while the switch is being powered by the Cisco RPS 2300.

Computer networking devices are units that mediate data in a computer network. Computer networking devices are also called network equipment, Intermediate Systems (IS) or InterWorking Unit (IWU). Units which are the last receiver or generate data are called hosts or data terminal equipment.
The Internet has truly revolutionized the way we communicate. If you actually think about it, the Internet is computer networking at the highest scale of complexity. It’s a continuous link of connected computers that spreads worldwide. How is data transfer and the implementation of networking protocols made possible in this colossal network? 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. Router, switch, hub and bridge are networking devices that act as mediators at various levels of this networking model.
What are the differences in the design and functioning of these networking devices: router, switch, hub and bridge?
Every one of these network devices which we compare in the following is a part of every Large Area Network (LAN), Wide Area Network (WAN) or small private networks. They integrate and connect the network at various levels, while providing control over data flow.
The main differences in functionality of Router, Switch, Hub and Bridge
A computer network connected to the Internet is designed to be a self-regulating network that can guarantee the transmission of data to right destinations and regulate overall data transfer. The network can be primarily divided into two types of devices which are terminals (connected computers) and control elements or connecting devices. The role router, switch, hub and bridge play in a computing network determines their basic functionality and difference.
Two or more computing networks are connected together by a router. It is charged with the responsibility of controlling the inter network data traffic. They are highly intelligent devices with embedded software that are used to control the flow of data packets across diverse networks.
A network 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.
A hub connects 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.
A network bridge is nothing more than a type of switch. While a switch has multiple connection ports, a bridge has a single connection port. In the next section, let us have a look at the features of each one of these devices in more detail.
Referring to OSI model layers, a router is functional on the network layer of the OSI model, which 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. You might want to check out the OSI model diagram to understand the functions of these devices better.
Network switches are 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. A bridge is just a type of network switch that connects two network segments together. Like switches, they too operate at the data link layer.
All these networking devices provide connectivity and help regulate Internet traffic through local and global Internet networks. Tips of identifying what are main networking hardware help you know the role and function of router, switch, hub and bridge in a network. So which network equipment you select depends on what you need in your home network or business network.
Common basic networking devices:
Router: a specialized network device that determines the next network point to which it can forward a data packet towards the destination of the packet. Unlike a gateway, it cannot interface different protocols. Works on OSI layer 3.
Bridge: a device that connects multiple network segments along the data link layer. Works on OSI layer 2.
Switch: a device that allocates traffic from one network segment to certain lines (intended destination(s)) which connect the segment to another network segment. So unlike a hub a switch splits the network traffic and sends it to different destinations rather than to all systems on the network. Works on OSI layer 2.
Hub: connects multiple Ethernet segments together making them act as a single segment. When using a hub, every attached all the objects, compared to switches, which provide a dedicated connection between individual nodes. Works on OSI layer 1.
Repeater: device to amplify or regenerate digital signals received while sending them from one part of a network into another. Works on OSI layer 1.
Some hybrid network devices:
Multilayer Switch: a switch which, in addition to switching on OSI layer 2, provides functionality at higher protocol layers.
Protocol Converter: a hardware device that converts between two different types of transmissions, such as asynchronous and synchronous transmissions.
Bridge Router (B router): CombineS router and bridge functionality and are therefore working on OSI layers 2 and 3.
Hardware or software components that typically sit on the connection point of different networks, e.g. between an internal network and an external network:
Proxy: computer network service which allows clients to make indirect network connections to other network services
Firewall: a piece of hardware or software put on the network to prevent some communications forbidden by the network policy
Network Address Translator: network service provide as hardware or software that converts internal to external network addresses and vice versa
Other hardware for establishing networks or dial-up connections:
Multiplexer: device that combines several electrical signals into a single signal
Network Card: a piece of computer hardware to allow the attached computer to communicate by network
Modem: device that modulates an analog "carrier" signal (such as sound), to encode digital information, and that also demodulates such a carrier signal to decode the transmitted information, as a computer communicating with another computer over the telephone network
ISDN terminal adapter (TA): a specialized gateway for ISDN
Line Driver: a device to increase transmission distance by amplifying the signal. Base-band networks only.
Dell Inc.’s deal on Wednesday to buy Force10 Networks will give the world's second-largest computer maker inroads into Cisco Systems Inc.’s turf -- networking.
Force10 is a data center networking company that makes Ethernet switchers and routers, and focuses on serving booming social media companies like Facebook and Zynga as well as giants like Google Inc.
With the acquisition of Force10 at an undisclosed price, Dell is creating a more serious competitor to Cisco, adding to the networking giant's troubles.
Cisco is already facing intense competition from smaller networking companies like Juniper Networks Inc., Check Point Software Technologies, F5 Networks Inc. and Riverbed Technology Inc.
Cisco's switching business has seen sales fall in recent quarters, and analysts have argued the company has stretched itself too thin by making several large acquisitions in the consumer market, causing it to lose focus of its core switching and routing businesses.
Force10, which generated about $50 million in revenue in the first quarter of 2011, has an edge over competitors.
Cisco, Juniper and Brocade Communications Systems Inc. all provide switching and routing technology, although very few like Force10 have the technological capability that creates the backbone of the major data centers, sources said.
The deal also means that Dell is no longer interested in buying networking equipment supplier Brocade, whose market capitalization is $2.8 billion, sources said. Dell was reported to be eyeing Brocade as well.
Over the past three years Dell has expanded its enterprise portfolio through acquisitions to include server and storage services.
In May, Dave Johnson, Dell's senior vice president of corporate strategy, told Reuters that it will continue to seek companies with valuations in the $1 billion to $5 billion range.
Dell was advised by Evercore Partners on the Force10 deal. The transaction was the first for technology investment banker Eric Mandl at his new firm. Tor Braham, head of technology M&A at Deutsche Bank, led the deal for Force10.
SALE VERSUS IPO
Force10's decision to sell to Dell is the latest in a string of private technology companies in the sector that are opting to sell rather than go public, as tech giants looking to build a broader suite of services swoop in with rich offers.
Force10 had filed its initial public offering with the Securities and Exchange Commission last year.
But in 2011, the company started discussions with a few interested parties over a sale, one source said.
Other companies that have in recent months opted to sell rather than go public include Internet video conferencing service Skype, which sold to Microsoft Corp for $8.5 billion, and Web hosting company Go Daddy which sold itself to a private equity consortium led by KKR and Silver Lake this month for $2.25 billion.

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).
