  • System and method for reducing traffic loss while using loop free alternate routes for multicast only fast reroute (MoFRR)
    Patent number: 9699073
    Abstract: A system, method and apparatus for adapting operation of a router configured to receive commonly sourced traffic via primary and secondary Upstream Multicast Hop (UMH) links, wherein the secondary path is cached for a predetermined period of time to avoid data loss upon restoration of the primary path.

  • Method and system for identifying an outgoing interface using openflow protocol
    Patent number: 9686137
    Abstract: A method for using OpenFlow protocol to configure an OpenFlow-enabled switch is disclosed. In the embodiment, the method involves decoding an OpenFlow flow entry from a flow mod message, the flow entry including two or more actions, searching a Service Access Point (SAP) match table for an outgoing interface having attributes that match the two or more actions, and updating a flow table on the OpenFlow-enabled switch to include the decoded flow entry when an outgoing interface having attributes that match the two or more actions is found.

  • Method and system for identifying an incoming interface using openflow protocol
    Patent number: 9667440
    Abstract: A method for using the OpenFlow protocol to configure an OpenFlow-enabled switch is disclosed. In the embodiment, the method involves decoding an OpenFlow flow entry from a flow mod message, the flow entry including two or more components comprising at least one of a match field and an experimenter field, searching a service access point (SAP) match table for an incoming interface having attributes that match the two or more components, and updating a flow table on the OpenFlow-enabled switch to include the decoded flow entry when an incoming interface having attributes that match the two or more components is found.
