Small playback lag in live streaming is important for time-critical and interactive applications such as live stock, market updates, sports and remote education. In this paper, we present Elite addresses the playback lag problem in peer-assisted live streaming systems. Instead of deploying a large initial offset to all the users, Elite seeks the possibility of initializing users with layered proportional...
It has been well known that network coding can achieve better network throughput in certain topologies by allowing coding at intermediate nodes. However, the benefit of network coding in P2P content distribution is controversial in recent literatures. In this paper, we seek to investigate how network coding performs in a BitTorrent-like protocol from a practical perspective. To validate the benefit...
Video-on-demand (VoD) service on the Internet has been surprisingly popular during these years. And it is being greatly enhanced by the emergence and maturation of both the peer-to-peer (P2P) schema and network coding (NC) technology. P2P-based solution can make VoD systems obtain high scalability. The introduction of network coding improves the content distributing efficiency of the system. Meanwhile,...
P2P Live media streaming is becoming popular in the Internet. There still remain some neglected problems such as playback lag, which is extremely sensitive for users in some urgent and interactive scenarios. In addition, many current studies were based on theoretical assumptions and never be turned into reality. In this paper, we present SonicStream, a full implementation of live P2P media streaming...
Video-on-demand (VoD) service has been greatly enhanced with the maturation of both peer-to-peer (P2P) and network coding (NC) technology. Digital video cassette recording (VCR) function provides users with more freedom that they can choose different playback modes while viewing video clips. Besides, users are able to switch between different scenes with the support of video-segmentation. Based on...
Nowadays, the real practice of network coding in wireline networks is focused on the P2P overlay networks. Although it can help to utilize network resources more efficiently, P2P network coding does not exhibit benefits in terms of the maximum throughput. Our work aims to implement network coding at the IP layer, which is an idea not fundamentally new, but with little real practice because of the...
