  • Computing label-switched data communication paths
    Patent number: 10924394
    Abstract: Methods, systems, and computer readable media for computing label-switched data communication paths are disclosed. An example method includes receiving, by a path computation element (PCE) implemented on at least one processor, synchronization status information for routing nodes in a label-switched network. The method includes receiving, by the PCE, a request for a label-switched path (LSP) from a client. The method includes determining, by the PCE, a responsive LSP based at least in part on the synchronization status information. The method includes sending, by the PCE, an explicit route object (ERO) for the responsive LSP to the client.

  • Methods, systems, and computer readable media for advertising network security capabilities
    Patent number: 10581802
    Abstract: Methods, systems, and computer readable media for advertising network security capabilities are disclosed. According to one method, the method occurs at a network node. The method includes receiving a first route advertisement message that includes network security capabilities information indicating capabilities of a network security system associated with a route. The method also includes receiving a packet associated with a packet flow. The method further includes directing the packet associated with the packet flow to a downstream network node associated with the network security system.
