LAN switching (2)
LAN switch supports:
- full-duplex communication: effectively doubles the throughput
- media-rate adaptation : translation between 10 and 100 Mbps
- dedicated collision-free communication between network devices
- multiple simultaneous conversation: forwarding or switching
- several packets at the same time
LAN switch forwarding
- store-and-forward :error checking is performed (cyclic redundancy check); errorous frames are discarded
- cut-through: latency is reduced by eliminating error checking; only the destination address is copied into the on-board buffers
