摘　　要：文章针对6PE校园网的特点,提出一种基于节点拥塞度约束的拥塞控制路由算法,在保证用户流QoS请求的同时,通过调整节点拥塞度来进行负载均衡,从而达到拥塞避免的目的。仿真实验结果表明,该策略能从一定程度上提高网络吞吐量及减少请求包的阻塞率,有利于流媒体传输。Aiming at the features of Campus network？based on IPv6 over MPLS, a new algorithm of congestion control is presented which introduces link-congestion degree constraint while guaranteeing QoS constraints to find a feasible path for services. Using the new algorithm, the congestion degree should be retained up to an appropriate level that can make network load balance, thus congestion will probably be avoided. The simulation results show that the proposed algorithm can improve throughput and decrease call blocking rate in a certain extent. It is suitable for transferring streaming media.
