Learning Bridges Eliminate manual configuration by learning which addresses are on which LANs Basic approach If a frame arrives on a port, then associate its source address with that port As each host transmits, the table becomes accurate What if a node moves? Table aging Associate a timestamp with each table entry Refresh timestamp for each new packet with same. Bridges versus Routers. • An enterprise network (e.g., university network) with a large number of local area networks (LANs) can use routers or bridges. – s: LANs interconnection via bridges – Late s and early s: increasingly use of routers – Since . With the help of the BPDUs, bridges can: • Elect a single bridge as the root bridge. • Calculate the distance of the shortest path to the root bridge • Each LAN can determine a designated bridge, which is the bridge closest to the root. The designated bridge will forward packets towards the root bridge.

With the help of the BPDUs, bridges can: • Elect a single bridge as the root bridge. • Calculate the distance of the shortest path to the root bridge • Each LAN can determine a designated bridge, which is the bridge closest to the root. The designated bridge will forward packets towards the root bridge. Switches and Bridges COS Computer Networks Spring (MW in COS ) Guest Lecture – Bridge/switch needs to construct a forwarding table if the network contains a cycle of switches – Either accidentally, or by design for higher reliability. Bridges with routing function between LANs are also available. Computer 1 wishes to talk to computer 3 on the same network. The packet sent by computer 1 will contain the physical address of computer 3 that will also be received by the bridge device connecting the two LAN segments. Learning Bridges Eliminate manual configuration by learning which addresses are on which LANs Basic approach If a frame arrives on a port, then associate its source address with that port As each host transmits, the table becomes accurate What if a node moves? Table aging Associate a timestamp with each table entry Refresh timestamp for each new packet with same. Bridges versus Routers. • An enterprise network (e.g., university network) with a large number of local area networks (LANs) can use routers or bridges. – s: LANs interconnection via bridges – Late s and early s: increasingly use of routers – Since . • Bridges use backward learning in recording source addresses on transmissions. • Unlike repeaters, bridges will not forward a frame onto another LAN segment if it knows about the location of the destination node. • Bridge management gets more complicated when loops are possible in the frame route. Computer Networks: Bridges 4.It contains well written, well thought and well explained computer science Network Devices (Hub, Repeater, Bridge, Switch, Router, Gateways and Brouter). 1. SMU. CSE / 9.
