    • A method for communication over a bi-directional ring network (22) includes provisioning a virtual private local area network service (VPLS) over the bi-directional ring network. The VPLS includes connection termination points (54) provisioned respectively on a plurality of the nodes (24) so as to connect each of the plurality of the nodes to a second network (30) external to the ring network. As long as the nodes and spans are fully operational, one or more of the connection termination points are maintained in a deactivated state, so that no more than one of the connection termination points to the second network is active. The nodes exchange messages indicative of a failure associated with the bi-directional ring network, causing at least one of the deactivated connection termination points to be activated so as to maintain connectivity among the users of the VPLS without creating a loop in the VPLS via the second network.
    • 一种用于通过双向环网(22)进行通信的方法包括通过双向环网提供虚拟专用局域网服务(VPLS)。 VPLS包括分别在多个节点(24)上提供的连接终止点(54),以将多个节点中的每一个连接到环网外部的第二网络(30)。 只要节点和跨度完全可操作,则一个或多个连接终止点被维持在去激活状态,使得不超过一个到第二网络的连接终端点是活动的。 节点交换指示与双向环形网络相关联的故障的消息,导致至少一个停用连接终止点被激活,以便在VPLS的用户之间保持连接,而不经由VPLS中的环路创建循环 第二网络。
