  • Enhanced protocol independent multicast source registration over a reliable transport
    Patent number: 9660898
    Abstract: In one example, a method includes exchanging, by a first routing device and with a second routing device, targeted hello messages using a Protocol Independent Multicast (PIM) protocol to establish a targeted neighbor connection between the first routing device and the second routing device, wherein the first routing device exchanges the targeted hello messages with the second routing device via at least one intermediate routing device, and wherein at least one of the first or second routing device comprises a rendezvous point (RP). The example method further includes processing, by the first routing device using the targeted neighbor connection, a register message that includes multicast stream data elements, wherein each multicast stream data element identifies a source address and a group address that are collectively associated with a respective multicast stream, and wherein each multicast stream data element further indicates whether the respective multicast stream is active or withdrawn.
