Name-based neighbor discovery and multi-hop service discovery in information-centric networks

Abstract

A content router, comprising a plurality of physical links to other nodes in an information centric network, a receiver coupled to the plurality of physical links configured to receive messages, a transmitter coupled to the plurality of physical links configured to transmit messages, and a service publishing and discovery (SPD) module comprising a processor and memory device coupled to the receiver and to the transmitter, wherein the SPD is configured to store status updates of the physical links, wherein the SPD is configured to determine a next hop and a number of hops to forward a received message based on a prefix in a name-based service discovery protocol name of a received message.

Problems solved by technology

) However, this EF mechanism may not be efficient because a single discovery session requires the exchange of multiple rounds of Interest Data messages, depending on the number of service names to be excluded, and it may be difficult for the end user to decide when the discovery protocol should end , because the number of service names to discover is unknown
