  • Method and apparatus for simultaneous support of fast restoration and native multicast in IP networks
    Patent number: 8964571
    Abstract: The invention includes a method and apparatus for simultaneously supporting restoration and native multicast at a router in an Internet Protocol (IP) network. In one embodiment, a method includes establishing a point-to-point pseudowire having an endpoint at the router, associating the point-to-point pseudowire with an IP interface, and associating a multicast protocol with the IP interface. The point-to-point pseudowire is adapted for supporting restoration in response to a failure. The association of the multicast protocol with the IP interface enables running of the multicast protocol in a manner that gives an appearance that the multicast protocol is running natively on an IP link.
