一种T-MPLS环网标签分配方法
摘要：
一种T－MPLS环网标签分配方法，涉及环网标签分配，其步骤为：1.为节点分配全局TUNNEL标签；2.为业务分配局部PW标签；3.上话方向封装的TUNNEL标签为宿节点的TUNNEL标签，封装的PW标签为宿节点为该业务分配的PW标签；下话方向终结的TUNNEL标签为本节点的TUNNEL标签，终结的PW标签为本节点为该业务分配的PW标签。本发明所述的方法，以目的节点为导向进行TUNNEL配置，TUNNEL标签总数等于所有节点总数，因此TUNNEL标签总数不会随着业务的增加而增加，而且标签可以被所有节点重复使用也不会引起误连接，这使得在实现业务的环网WRAPPING保护和STEERING保护变得容易。
摘要（英）：

The invention discloses a distribution method for a T-MPLS ring network label and relates to ring network label distribution. The method comprises the following steps: 1. global TUNNEL labels are distributed for nodes; 2. local PW labels are distributed for services; and 3. the TUNNEL labels encapsulated in the up direction are TUNNEL labels of old nodes, and the encapsulated PW labels are PW labels which are distributed by the old nodes for the service; terminated TUNNEL labels in the down direction are TUNNEL labels of the node; and the terminated PW labels are PW labels which are distributed by the node for the service. The method carries out TUNNEL configuration by taking the destination node as guide and the total number of the TUNNEL labels is equal to the total number of all the nodes, therefore, the total number of the TUNNEL labels is not increased along with the increasing of services, and the labels can be repeatedly used by all the nodes without causing error connection, thus leading the ring network WRAPPING protection and STEERING protection for realizing services to become easy.
