Live Streaming with Content Centric Networking

Abstract

Media streaming is the killer application in current Internet. There are a variety of media streaming techniques in today's Internet, such as RTSP, HTTP live streaming and Adobe Flash etc. HTTP live streaming (HLS) is a popular and most promising technique as the protocol is based on the Internet workhorse protocol i.e. HTTP, and supported by HTML5 and mobile platform. Most of these media streaming techniques are based on TCP/IP, which is built on the traditional host-to-host network architecture. The host-to-host architecture is proved to be inefficient in content distribution with a lot of bandwidth waste, and it is complicated to deploy network service because of TCP/IP's location-dependence. Content Centric Networking (CCN) is a future Internet architecture which is targeted to solve the above problems by location-independent content naming and universal content caching in router. In this paper, we investigate both HTTP live streaming and CCN, and propose a design of CCN live streaming, which is a media streaming technique base on CCN. Finally, we demo our CCN live streaming on Android client, and conduct evaluation experiments. The results demonstrate that the CCN live streaming is a low-cost scheme and much easier to deploy and configure in operation compared with HTTP live streaming.
