Bridges/Switches interconnect multiple LAN segments/
hosts/ gateways at the data link layer. Most bridges/switches also provide MAC
address learning features that can reduce the unnecessary broadcast of frames
and thus collisions across all of the LAN segments/hosts to be interconnected.
They can also be used to interconnect different types of LAN technologies, e.g.
between a 10BT and a 100BT Ethernet segments. 802.1d Spanning Tree Protocol is
usually run by bridges/switches to automatically eliminate the formation of
loops within the interconnected LAN.
Keywords:
LAN interconnection, bridging, switching, loop.
