摘要：With the increasing variety of service types supported by the communication network, more and more requirements for bandwidth occurred. Different types of services have different characteristics in the aspects of importance, bandwidth demand, time-sensitive and so on. Customers’s requirements for the controllability and manageability of communication network are more and more demanding. The paper researches on policy-based transmition control technology in MPLS controllable and manageable communication network, proposes a new transmition control method. The method supports to create and to release the dynamical connection of MPLS TE or MPLS LSP, uses service-priority policy, bandwidth policy and degradation policy for policy decision. In order to improve the QoS of service-priority policy, Policy-Condition Maximum Matching Algorithm (PCMMA) is put forward. The principle of the policy-based transmition control in the MPLS communication network is explained. An experiment is performed to support the research. The experiment results show that the policy-based transmition control technology in MPLS communication network is effective and valid. It helps to improve the QoS of network and the utilization rate of network resource.
