摘要: With increasing demand for multimedia applications, local area network (LAN) technologies are rapidly being upgraded to provide support quality of service (QoS). In a that consists an interconnection multiple LANs via bridges, the QoS flow depends on length end-to-end forwarding path. IEEE 802.1D standard spanning tree is built among bridges loop-free frame forwarding. Albeit simple, this approach does not all-pair shortest paths. paper, we present novel bridge protocol, Spanning Tree Alternate Routing (STAR) Bridge Protocol, attempts find and forward frames over alternate paths provably shorter than their corresponding Being backward compatible 802.1D, our protocol allows cost-effective performance enhancement existing extended LAN by incrementally replacing few in new STAR bridges. We develop strategy ascertain locations maximum gain. Our study shows can significantly improve when deploying protocol.
