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.
Switch 4200G - Gigabit. 12, 24 or 48 Gb ports including 4 Dual Personality Ports (2 × Gb or SFPs). 12-Port module has one 10-Gigabit expansion slot; other units have two 10-Gigabit expansion slots. One PoE model. Units can directly take a 10GE XENPAK, or can receive a 1-Port 10GE XFP module. Supports Layer 2 switching and Layer 3 static routing.
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.

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 ...
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
It was best known for its Layer 2 & 3 Ethernet switches. Foundry Networks was the first company to build and ship a gigabit Ethernet switch in 1997; to build a Layer 3 switch, also in 1997; to build the first Layer 4-7 switch in 1998 and to include 10 Gigabit Ethernet single connectors in its boxes (since 2001).

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. [7] [8] In 2008 Layer 3 routing support, secure web access with https and TACACS+ were added to the software in version 4 ...
Switched fabric or switching fabric is a network topology in which network nodes interconnect via one or more network switches [1] (particularly crossbar switches).Because a switched fabric network spreads network traffic across multiple physical links, it yields higher total throughput than broadcast networks, such as the early 10BASE5 version of Ethernet and most wireless networks such as Wi-Fi.
