Title
(EN) A method and system for optimizing resources for establishing pseudo-wires in a multiprotocol label switching network
(ZH) 优化用于在MPLS网络中建立伪线的资源的方法和系统
Abstract
(EN)
A method for establishing a pseudo-wire connection between first and second switches in a packet switched network, the method comprising: sending a label mapping message to the second switch requesting that the pseudo-wire connection be established with the first switch; reserving resources for the pseudo-wire connection at the first switch; receiving a label withdraw message from the second switch if the second switch has insufficient resources for the pseudo-wire connection and, in response to the label withdraw message, releasing the resources for the pseudo- wire connection at the first switch; and, activating the pseudo-wire connection if the second switch has sufficient resources for the pseudo-wire connection, thereby optimizing resources for establishing pseudo-wire connections of each of the first and second switches.

(ZH)

一种用于在分组交换网络中的第一和第二交换机之间建立伪线连接的方法,包括:发送标签映射消息给请求与所述第一交换机建立伪线连接的所述第二交换机;在所述第一交换机预留用于所述伪线连接的资源;如果所述第二交换机不具有用于该伪线连接的足够资源则接收来自该第二交换机的标签撤销消息,并且响应于该标签撤销消息而释放所述第一交换机处的用于该伪线连接的资源;以及,如果所述第二交换机具有用于该伪线连接的足够资源则激活该伪线连接,由此优化用于建立所述第一和第二交换机中每一个的伪线连接的资源。
