Abstract
A computing device or control plane device functioning as or implementing the functions of a network node in a multicast communication network. The multicast communication network includes a multicast tree to provide connectivity from a common source node to one or more multicast recipient nodes. The multicast communication network further includes a set of secondary paths to provide redundancy to the multicast tree. The computing device executes a plurality of virtual machines for implementing network function virtualization (NFV), wherein a virtual machine from the plurality of virtual machines is configured to implement a method for an enhanced fast re-route mechanism to provide increased failure coverage to the multicast communication network.
