SYSTEM AND METHOD FOR MULTI-SOURCE MULTICASTING IN CONTENT-CENTRIC NETWORKS
First Claim
1. A computer-executable method for updating routing information associated with a multicast group in an information-centric network (ICN), the method comprising:
- receiving, by a first node in the ICN, an update message for the multicast group from a neighbor node, wherein the multicast group includes a root anchor node and a number of anchor nodes with the root anchor node having a smaller name than the anchor nodes, and wherein the update message specifies a prefix associated with the multicast group and the root anchor node of the multicast group;
selecting, based on topology information stored on the first node, from neighbors of the first node one or more next-hop neighbors that meet a notification condition; and
forwarding the update message to the one or more next-hop neighbors.

Abstract
One embodiment of the present invention provides a system for updating routing information associated with a multicast group in an information-centric network (ICN). During operation, a first node in the ICN receives an update message for the multicast group from a neighbor node. The multicast group includes a root anchor node and a number of anchor nodes with the root anchor node having a smaller name than the anchor nodes. The update message specifies a prefix associated with the multicast group and the root anchor node of the multicast group. The system selects, based on topology information stored on the first node, from neighbors of the first node one or more next-hop neighbors that meet a notification condition, and forwards the update message to the one or more next-hop neighbors.

8. A non-transitory computer-readable storage medium storing instructions that when executed by a computing device cause the computing device to perform a method for updating routing information associated with a multicast group in an information-centric network (ICN), the method comprising:
-
receiving, by a first node in the ICN, an update message for the multicast group from a neighbor node, wherein the multicast group includes a root anchor node and a number of anchor nodes with the root anchor node having a smaller name than the anchor nodes, and wherein the update message specifies a prefix associated with the multicast group and the root anchor node of the multicast group; selecting, based on topology information stored on the first node, from neighbors of the first node one or more next-hop neighbors that meet a notification condition; and forwarding the update message to the one or more next-hop neighbors. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer system for updating routing information associated with a multicast group in an information-centric network (ICN), the system comprising:
-
a processor; and a storage device coupled to the processor and storing instructions which when executed by the processor cause the processor to perform a method, the method comprising; receiving, by a first node in the ICN, an update message for the multicast group from a neighbor node, wherein the multicast group includes a root anchor node and a number of anchor nodes with the root anchor node having a smaller name than the anchor nodes, and wherein the update message specifies a prefix associated with the multicast group and the root anchor node of the multicast group; selecting, based on topology information stored on the first node, from neighbors of the first node one or more next-hop neighbors that meet a notification condition; and forwarding the update message to the one or more next-hop neighbors. - View Dependent Claims (16, 17, 18, 19, 20, 21)
