Self-routing multicast in a software defined network fabric
First Claim
1. A system, comprising:
- a switch controller comprising a hardware processor and logic integrated with and/or executable by the processor, the logic being configured to;
receive a multicast data stream join request from a source device in a network, wherein the multicast join request is an internet group management protocol (IGMP) join request;
create a multipath identifier (ID) for the multipath data stream;
create a series of path identifiers (IDs) for each intermediate switch in the network based on a local network topology database, each path ID being associated with a desired output port bitmap; and
transmit the multipath ID and a path ID to a source of the multicast data stream, the path ID corresponding to the source of the multicast join request,wherein broadcast and/or multicast routing tables are not used by the intermediate switches due to implementation of the path IDs specific to each intermediate switch to create a broadcast group.

Abstract
Methods, systems, and computer program products presented herein provide for self-routing multicast. In one embodiment, a system includes a switch controller including a hardware processor and logic integrated with and/or executable by the processor, the logic being adapted to receive a multicast data stream join request from a source device in a network, create a multipath identifier (ID) for the multipath data stream, create a series of path identifiers (IDs) for each intermediate switch in the network based on a local network topology database, each path ID being associated with a desired output port bitmap, and transmit the multipath ID and a path ID to a source of the multicast data stream, the path ID corresponding to the source of the multicast data stream join request.

9. A computer program product for providing self-routing multicast, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code readable/executable by a processor to:
-
receive, using the processor, a multicast data stream join request from a source device in a network; create, using the processor, a multipath identifier (ID) for the multipath data stream; create, using the processor, a series of path identifiers (IDs) for each intermediate switch in the network based on a local network topology database, each path ID being associated with a desired output port bitmap; and transmit, using the processor, the multipath ID and a path ID to a source of the multicast data stream, the path ID corresponding to the source of the multicast join request. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for providing self-routing multicast, the method comprising:
-
receiving, using a switch controller, a multicast data stream join request from a source device in a network; creating a multipath identifier (ID) for the multipath data stream; creating a series of path identifiers (IDs) for each intermediate switch in the network based on a local network topology database, each path ID being associated with a desired output port bitmap; and transmitting the multipath ID and a path ID to a source of the multicast data stream, the path ID corresponding to the source of the multicast join request. - View Dependent Claims (18, 19, 20)
