Bridges/SwitchesEdit

A network bridge connects multiple network segments at the data link layer (Layer 2) of the OSI model. In Ethernet networks, the term bridge formally means a device that behaves according to the IEEE 802.1D standard. A bridge and a switch are very much alike; a switch being a bridge with numerous ports. Switch or Layer 2 switch is often used interchangeably with bridge.

Interaction with Network Management (NM)Edit

Bridges aid NM by self-learning

Bridges can analyze incoming data packets to determine if the bridge is able to send the given packet to another segment of the network, which means bridges do not need to configure.

NM may specify whether to store-and-forward or cut-through, or error rate threshold for changing mode.
