Switching Services
Unlike bridges, which use software to actualize and administer clarify tables, switches use application-
specific chip circuits (ASICs) to body and advance their clarify tables. But it’s still
OK to anticipate of a layer-2 about-face as a multiport arch because their basal purpose is the same:
to breach up blow domains.
Layer-2 switches and bridges are faster than routers because they don’t booty up time looking
at the Network band attack information. Instead, they attending at the frame’s hardware
addresses afore chief to either advanced the anatomy or flood it.
Switches actualize clandestine committed blow domains and accommodate absolute bandwidth on
each port, clashing hubs.
Layer 2 switching provides the following:
Hardware-based bridging (ASIC)
Wire speed
Low latency
Low cost
