    • The invention includes a method and apparatus for configuring logical connectivity for a network comprising a plurality of nodes. A method includes determining a physical topology of the network, determining a set of LSP paths based on the physical topology of the network, and determining a set of LSPs using the set of LSP paths, where the set of LSPs includes a plurality of LSPs adapted for providing full logical connectivity between the nodes of the network. The physical topology is determined using information indicative of physical connectivity between nodes of the network. The set of LSP paths includes, for each pair of nodes in the network, at least two logical paths between the nodes of the node pair. The set of LSPs includes a plurality of LSPs adapted for providing full logical connectivity between the nodes of the network. The full logical connectivity between the nodes of the network may be maintained in response to physical topology change events, such as addition of nodes to the network removal of nodes from the network, and the like.
    • 本发明包括一种用于配置包括多个节点的网络的逻辑连接性的方法和装置。 一种方法,包括确定网络的物理拓扑,基于网络的物理拓扑确定一组LSP路径,以及使用该LSP路径集合确定一组LSP,其中该LSP组包括多个适配的LSP 用于在网络节点之间提供完整的逻辑连接。 使用指示网络的节点之间的物理连接的信息来确定物理拓扑。 对于网络中的每对节点,LSP路径集合包括节点对的节点之间的至少两个逻辑路径。 该组LSP包括适于在网络节点之间提供完全逻辑连接的多个LSP。 可以响应于物理拓扑变化事件来维护网络节点之间的完全逻辑连接,诸如将节点从网络中除去节点等节点。
