—Information Centric Networking (ICN) proposes a new paradigm converting thin waist of networking from IP packet to named chunk. In the practical implementation of multiple ICN projects, applications based on ICN may not just focus on data distribution, but also service and functional ts. In this paper, an abstraction of service extensions over ICN is proposed, called Named Service Networking (NSN). It demonstrates necessary components to build functional services over ICN, including security, semantics, etc. A prototype of NSN is implemented over Named Data Networking (NDN) and evaluated to test its transmission efficiency, scalability and availability.
