Switches

Switches constantly monitor the traffic that comes across them and remote their internal connections automatically to provide the most efficient operation for the network. With the sophisticated layer-3 switches rapidly getting accepted in the market, the router market is getting considerable displaced. Layer-3 switching has significant price/performance advantages over routers on account of their topological flexibility. A packet-by-packet layer-3 switching facilities high speed routing and is interoperable with legacy routers. It also facilitates routing table construction and maintenance and investigates packets to determine their destination before forwarding them. Layer-3 switching is rapidly emerging as a standard for centralised networking. Also a network device that filters and forward frames based on the destination address of each frame. It is and advanced form of hub. Switches can provide dedicated bandwidth at each node. Due to this, the network traffic passing through one node does bot effect another node. A switch isintelligent and can turn on and off specific ports using software controls. Due to this, switches automate network configuration and hence increase network availability abd capability. Theswitch operates at the data link layer of the OSI model.
