摘要
千兆以太网中使用生成树协议来保证网络中不出现逻辑环路。但网络拓扑的生成树结构严重制约了千兆以太网的性能和可扩展性。本文提出无须完全阻塞产生循环的端口,只要禁止特定的拐弯集合,即可避免逻辑环路,并具体应用拐弯模型,设计了一种适合于千兆以太网的路由算法TR。模拟实验证明使用TR路由算法较之使用生成树算法而言网络性能有了明显的提高。
Gigabit Ethemet uses the Spanning Tree Protocol to ensure that there are no logical loops in the network. The spanning tree structure imposes a severe penalty on the performance and scalability of Gigabit Ethemets. This paper claims that it is enough to prohibiting a set of turns in the network instead of prohibiting a set of output ports, and proposes a novel routing algorithm named TR based on the turn model. The simulation results indicate that TR algorithm can improve the performance of the network significantly.
