Abstract
In general, techniques are described for providing current bandwidth usage information for one or more label switched paths (LSPs) to a path computation element (PCE) to trigger the PCE to dynamically modify a path computation domain of the PCE to manage network traffic within the domain. In some examples, a network router signals an LSP in a packet-switched network according to an allocated bandwidth for the LSP. The network router receives and maps the network packets to the LSP for transport along the LSP in accordance with forwarding information. The network router determines bandwidth usage information for the LSP that indicates a volume of the network packets mapped to the LSP and sends, in a notification message, the bandwidth usage information for the LSP to a path computation element that computes label switched paths for a path computation domain to trigger reoptimization of the path computation domain.
