摘要: 提出基于策略和流量特征的约束路由算法,算法根据网络资源和流量分布特征,为不同流预先分配带宽,优化网络资源的使用.将显式路由计算和故障恢复机制相结合,设计和实现基于MPLS(Multi Protocol Label Switch)的故障恢复系统,提高MPLS网络的生存性.Abstract: Based on network policy and traffic profile information, a new constrained routing algorithm for MPLS traffic engineering was proposed. The algorithm pre-allocates the network bandwidth resources to different traffic classes according to the traffic profile information. Through the combination of explicit route computation and fault recovery mechanisms , a MPLS based fault recovery system was designed and implemented. It was shown that both the utility of network resources and the survivability of MPLS traffic engineering system were enhanced through the treatments.
