Packet Switching Networks Packet Switching - Packets are relayed across network along the best route available.
Repeater = Physical layer - takes a weak signal and regenerates it - doesn't translate or filter anything - can move packets from on physical media to another (i.e. can connect thinet to fiber-optic) - they are cheap - will pass a broadcast storm
Bridge = Data Link layer - does everything a repeater does - reduce traffic by segmenting the network by using a routing table- regenerate the signal at the packet level - not suited to WANs slower than 56K - will pass broadcast storms - read the source and destination of every packet - pass packet with unknown destinations - connect dissimilar networks (i.e. Token Ring and Ethernet)
Router = Network layer - does filtering and isolating traffic - forwards particular protocols to particular addresses (other routers) - connect network segments - not all protocols are routeable (LAT and NetBEUI) - are used in complex network situations because they provide better traffic mgmt. than brides - don't pass broadcast traffic.
Brouter = combines best qualities of both a bridge and a Router - can act like a Router for one protocol and bridge all of the others (nonroutable) - delivers more cost-effective
