Abstract: In one embodiment, a node in a communication network receives a label switched path (LSP) request and in response, the node determines at least two equal cost paths, each path having one or more path-nodes. The node may then further determine a total bandwidth-based transition value for each path of the at least two equal cost paths and selects the path having a lower total transition value. Once selected, the node may establish the requested LSP over the selected path.

Abstract translation: 在一个实施例中，通信网络中的节点接收标签交换路径（LSP）请求，并且作为响应，节点确定至少两个相等的成本路径，每个路径具有一个或多个路径节点。 然后，节点可以进一步确定至少两个相等成本路径的每个路径的总带宽转换值，并选择具有较低总转换值的路径。 一旦选择，节点可以在所选路径上建立所请求的LSP。
