DYNAMIC TUNNEL REPORTING FOR PATH COMPUTATION AND TRAFFIC ENGINEERING WITHIN A COMPUTER NETWORK

Abstract:

In general, techniques are described for reporting dynamic tunnels to a path computation element (PCE) of a network to inform path computation by the PCE for traffic engineering within the network. In some examples, a method comprises generating, by a network device configured to route network packets within a network, a dynamic tunnel report message that includes dynamic tunnel description data for a dynamic tunnel that transports the network packets through the network, wherein the network packets transported by the dynamic tunnel each comprises an outer header that does not include a multiprotocol label switching (MPLS) transport label; and sending, by the network device, the dynamic tunnel report message to a path computation element (PCE) for a path computation domain to report the dynamic tunnel to the PCE for inclusion in path computation by the PCE for label switched paths of the network.
