In the IEEE 802.1D standard for bridges, a spanning tree is built among bridges for loop-free frame forwarding. Although this approach is simple, it does not support all-pair shortest paths. To provide quality-of-service (QoS) in LANs, the IEEE 802.1p standard specifies priority queuing in bridges. However, no existing bridge protocol supports path differentiation for frames of different priorities. In this talk, I will describe a novel bridge protocol that attempts to find alternate paths that are shorter than their corresponding tree paths on the standard spanning tree. The protocol makes use of the alternate paths to forward frames of different priorities using different paths. The protocol is backward compatible with the IEEE 802.1D standard and has a complexity that is comparable to that of the standard. ********************** Biography: King-Shan Lui received her B.Eng. degree (First-Class Honors) and MPhil. degree from the Hong Kong University of Science and Technology (HKUST) in 1994 and 1995 respectively.
