Abstract
In general, techniques are described for dynamically scheduling and establishing paths in a multi-layer, multi-topology network to provide dynamic network resource allocation and support packet flow steering along paths prescribed at any layer or combination of layers of the network. In one example, a multi-topology path computation element (PCE) accepts requests from client applications for dedicated paths. The PCE receives topology information from network devices and attempts to identify paths through a layer or combination of layers of the network that can be established at the requested time in view of the specifications requested for the dedicated paths and the anticipated bandwidth/capacity available in the network. The PCE schedules the identified paths through the one or more layers of the network to carry traffic for the requested paths. At the scheduled times, the PCE programs path forwarding information into network nodes to establish the scheduled paths.
