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.

Abstract: A controller at an IP (e.g., client) layer in a multi-layer network can request a network topology map from another controller at an optical (e.g., server) layer in the multi-layer network. The controller at the optical layer of the network can use a layer mapping function and common attributes between the formats used to describe the network topology map at the two layers to generate a common layer abstraction model representing the network topology map stored at the controller at the optical layer of the network. A controller-to-controller interface can translate and/or send the common layer abstraction model to the controller at the IP layer for processing data on the network.

Abstract: A device may identify a plurality of first values associated with network traffic of a label-switched path of a plurality of label-switched paths. The device may determine an adjustment policy based on the plurality of first values. The adjustment policy may include one or more factors associated with a plurality of second values. The plurality of second values may be determined based on the plurality of first values. The device may implement the adjustment policy in association with the label-switched path. A bandwidth reservation of the label-switched path may be adjusted based on the adjustment policy. The adjustment policy may be implemented for fewer than all of the plurality of label-switched paths.
