NRTS: Content name-based real-time streaming

Abstract

Content-Centric Networking (CCN) or Named-Data Networking (NDN) has been proposed as an alternative to the existing Internet architecture. In this paper, we propose Content Name-based Real-time Streaming (NRTS) to enhance the basic concept and implementation of CCN in order to improve streaming quality. NRTS utilizes “symbolic interest,” which eliminates segment identification, and “content-name-based streaming,” which enables per-content (instead of per-packet) streaming and multicasting using a rate control scheme based on network conditions. NRTS is more suitable for high-performance delay-sensitive real-time applications than the original CCN architecture. It avoids the generation of bursty interests and the need for complex operations such as setting the pipeline size. The results from the experiments conducted using simulations and testbeds show that NRTS attains higher throughput and scalability than the original CCN architecture.
