摘要:
A multipoint-to-multipoint service is provided between a set of edge nodes of a communications network. The network comprises at least two sub-networks and an intermediate node at a boundary between sub-networks. For each pair of edge nodes comprising an edge node in a first of the sub-networks and an edge node in a second of the sub-networks, a multi-segment pseudowire connection is configured between the pair of edge nodes. The pseudowire connection passing via at least one intermediate node. At the intermediate node forwarding data is configured which specifies a forwarding relationship between pseudowire segments corresponding to the multi-segment pseudowire connections. A topology of Label Switched Paths carry the multi-segment pseudowires. Edge nodes within a sub-network can be connected with a mesh topology or a hub-and-spoke topology.
摘要(中):
在通信网络的一组边缘节点之间提供多点对多点服务。 该网络包括至少两个子网络和在子网络之间的边界处的中间节点。 对于包括第一子网中的边缘节点和第二子网中的边缘节点的每对边缘节点,在所述一对边缘节点之间配置多段伪线连接。 通过至少一个中间节点的伪线连接。 在中间节点处,配置转发数据,其指定与多段伪线连接相对应的伪线段之间的转发关系。 标签交换路径的拓扑携带多段伪线。 子网络中的边缘节点可以与网状拓扑或中心辐射拓扑结合。
