摘要
分析了基于多协议标记交换(MPLS)可管可控网络的体系结构。论述了业务优先级策略、带宽策略和降级策略3种传送控制支持的策略。提出了用于业务优先级策略的策略条件最大匹配算法。对基于策略的MPLS通信网络的传送控制工作原理进行了阐述,并进行了实验验证。实验证明基于策略的MPLS通信网络传送控制方法可行、有效。
The architecture of policy-based controllable and manageable MPLS communication network is introduced,three kinds of policies are described including service-priority policy,bandwidth policy and downgrade policy.A policy-condition largest matching algorithm used for the service-priority policy is proposed,the operation principle of the transmition control of policy-based MPLS communication network is explained and also verified by experiment.The experiment proves that the policy-based transmition control method in MPLS communication network is effective and valid.
