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

Embodiment Construction

[0024] It should be understood at the outset that although an illustrative implementation of one or more embodiments is provided below, the disclosed systems and / or methods may be implemented using any number of currently known or available techniques. The invention should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, including the exemplary designs and implementations illustrated and described herein, but may be limited within the scope of the appended claims and their equivalents. Modify within the complete scope of the object.

[0025] What is disclosed in this paper is a name-based neighbor and service discovery scheme of ICN, including two basic protocols, such as a name-based neighbor discovery protocol and a name-based service discovery protocol. Applying these name-based neighbor discovery protocols and name-based service discovery protocols to information-centric networks (ICNs) such as content-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.
