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
