Interconnecting high-speed LANs and backbones

摘要

Transparent source routing, an algorithm that exploits the best features of the transparent spanning tree and source routing algorithms for medium-access-control (MAC) bridges used in local area network (LAN) interconnections, is presented. The scheme uses optimal routes, is transparent to end stations, and reduces bridge processing overheads. Aspects of the existing transparent spanning tree and source routing algorithms are described. A comparison of the new scheme with the two existing schemes is presented.
