7.2 Port Trunking
In telecommunications, trunking is a method for a system to provide network access
to many clients by sharing a set of lines or frequencies instead of providing them
individually. This is analogous to the structure of a tree with one trunk and many
branches. Trunking, is set by the configuration software, the two or more physical
ports get together into a logical path to increase the bandwidth between the switch
and the network node. Trunking is a packaging technology, it is a peer to peer link,
both ends of the link are switches, it can be a switch and a router, and also can be a
host, switch or router.
Based on port trunking function that allows between two or
more ports between switches, switches and routers, hosts the switch or router
connected in parallel to provide for the simultaneous transmission of higher bandwidth
and greater throughput, significantly entire network capacity. Trunking is more
economical to increase the bandwidth between the switch and network device, such
as servers, routers, workstations, or other switches. Trunking function is to integrate
more than one physical port (typically 2-4) to a logical channel.
