Patent ID: 8743681

Claim:
A method comprising: receiving, by one or more network devices, network topology and resource management information; generating, by the one or more network devices, a mapping between the network topology of a network and resource reservation paths associated with flows using the network based on the network topology and resource management information; generating, by the one or more network devices, a failure recovery plan (FRP) based on the mapping, wherein the FRP instructs one or more other network devices on how to manage a failure such that one or more resource reservation paths associated with flows impacted by the failure are not deleted and a virtual interface is created that emulates an interface of a failed network device; loading, by the one or more network devices, the FRP on the one or more other network devices; detecting the failure; executing the FRP, by the one or more other network devices, wherein the executing comprises: creating a backup path, wherein the creating comprises: creating, on one of the one or more other network devices, the virtual interface that emulates the interface of the failed network device; and creating a connection between the virtual interface and a physical interface on the one of the one or more other network devices; and migrating the flows impacted by the failure to the backup path.
