On-Path Resolver Architecture for Mobility Support in Information Centric Networking

Abstract

Video traffic shares a large portion of the current Internet bandwidth. One of the objectives of designing Named Data Networking (NDN) is to reduce the burden of the large content delivery. Since mobile devices are the prime means of content access for many users, NDN is also required to support mobility. In this paper, we propose an architecture and mechanism called On-Path Resolver Architecture (OPRA) for NDN to support both consumer and producer mobility while maintaining scalability. OPRA exploits the semantics of hierarchical-name-based routing and places route resolvers on multiple points on a path to a content. The series of resolvers on a path provides means to contain naming scope and makes the system scalable while supporting mobility.
