Latest Patents

One of his latest patents is titled "Method to transport bidir PIM over a multiprotocol label switched network." This invention provides a method, system, and apparatus for transporting bidirectional Protocol Independent Multicast (PIM) over a multiprotocol label switched network. The method involves receiving a multicast packet at a network element, which includes an upstream label. The invention further identifies a Multicast Distribution Tree (MDT) rooted at a rendezvous point and forwards the packet along the MDT based on the upstream label. Additionally, the MDT can be identified from a downstream label, allowing the packet to be forwarded away from the rendezvous point.

Another significant patent is "System and method for detecting loops for routing in a network environment." This method includes receiving a label-mapping message at a first router, which does not record the message. The first router sends the label mapping message toward a root router of a Multipoint Label Switched Path (MPLSP) in the network. The method evaluates a path vector sent from the root router to determine if the first router's address is part of the path vector. If it is present, a loop is identified in the network, preventing the installation of the label mapping.
