Opportunistic Quality Adaptation for Scalable Video Streaming in Information Centric Networks

In these modern days, video streaming is the major portion of Internet traffic. To cope with the increasing demand Information Centric Networking (ICN) architecture has been proposed. Layered video, encoded with Scalable Video Coding (SVC), are envisioned to be very beneficial in CCN. In this paper we propose a mechanism for video quality selection that opportunistically request additional enhancement layers of SVC to fully utilize advantages of CCN routers ’ content caching. We enable the routers to take decision of discard the forwarding of outdated optional enhancement layers of the video in order to reduce unnecessary traffic inside the Network. 1
