EVALUATING A SWITCH


Switch, a network device that enables complex networks to be separated into multiple "collision domains"

Evaluate appropriateness of switch

Don't route: IP network can be addressed without Layer 3 routing; switches know hardware number

Dedicates path for each end system

Frame (switches packets) and cell switching (more deterministic) can be combined into mixed speed networks

Implementing can require change-out of entire wiring closet

LAN switches can result in traffic exceeding backbone transmission capacity

Central point of failure

Cannot provide end system quality of service

Cannot integrate and distribute data, video, voice over single wiring infrastructure with single adapter set

Fully switched environment more secure but more expensive than router
