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...
Graphics processing unit (GPU) has evolved into a general-purpose computing platform. Inspired by the GPU technology advantage, this paper concerns the design and performance evaluation of practical GPU-accelerated server architecture for Video-on-Demand (VoD) services with network coding. Following the proposal of an optimized network coding algorithm based on parallel threads on GPU, a GPU-Accelerated...
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...
