Switch 5500 - Fast Ethernet. 28- and 52-port models. Two PoE models. Stackable, 24 or 48 10/100 ports plus four SFP Gigabit Ports. One model 24 100 Mb SFPs plus 2 × Gb and 2 × SFP Gigabit Ports. Supports Layer 2 switching and Layer 3 static routing, RIP, and multicast routing (OSPF, PIM).
This product line became available in 2007 with software release 4.0 [4] [5] and the device was demonstrated in March at the 'Spring VoiceCon 2007'. [6] In March 2007 the product started to ship, and then in May 2007 a detailed evaluation between this switch and two competitor's switches identified that this switch had a better performance and better total cost of ownership.
A network switch is a multiport network bridge that uses MAC addresses to forward data at the data link layer (layer 2) of the OSI model. Some switches can also forward data at the network layer (layer 3) by additionally incorporating routing functionality. Such switches are commonly known as layer-3 switches or multilayer switches.

Networking hardware typically refers to equipment facilitating the use of a computer network. Typically, this includes routers, switches, access points, network interface cards and other related hardware. This is a list of notable vendors who produce network hardware.
Switching uses different kinds of network switches. A standard switch is known as a layer-2 switch and is commonly found in nearly any LAN. Layer-3 or layer-4 switches require advanced technology (see managed switch) and are more expensive and thus are usually only found in larger LANs or in special network environments.
A data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node. [3] It works on OSI layer 3. [4] Switch: a multi-port device that connects devices together at the same or different speeds on a computer network, by using packet switching to receive ...
Multiservice Switch (MSS) is originally a Nortel line of routers, historically called Passport, designed for carrier core and edge routing. They run the Passport Carrier Release operating system. The MSS has a significant installed base, with over 40,000 switches sold. As of 27 September 2010, this product line was sold to Ericsson. [1] [2]
The core network provides high-speed, highly redundant forwarding services to move packets between distribution-layer devices in different regions of the network. Core switches and routers are usually the most powerful, in terms of raw forwarding power, in the enterprise; core network devices manage the highest-speed connections, such as 10 ...
