Multi-publisher Routing Protocol For Named Data Networks


A multi-publisher routing system facilitates forwarding an Interest to multiple publishers associated with a namespace. During operation, network devices across a computer network can perform distance-vector routing with one or more network neighbors to determine a network topology. Also, one or more network devices may receive a namespace-join message from one or more publishers that are to provide content objects for the namespace. These network devices that receive the namespace-join message can construct an acyclic graph that includes one or more publishers for the namespace, and includes one or more forwarder nodes that form network paths between the one or more publishers. Then, when a network node in the acyclic graph receives an Interest message that specifies a name prefix associated with the namespace, this network node can forward the Interest message along the acyclic graph to one or more publishers associated with the namespace.
