Improving the Video Data Lookup Efficiency in Peer-to-Peer Live Streaming Network

Zhuo Chen, Gang Feng, and Yi Lu
Abstract—DHTs have been recently used in Peer-to-Peer (P2P) live streaming systems to improve video playback continuity and data segment availability. However, existing solutions are not especially optimized for live streaming applications. There are still some challenging issues to be addressed, especially the low search efficiency for time-sensitive applications. In this paper, we propose an efficient one-hop DHT lookup framework called Streaming DHT (SDHT), dedicated to supporting media data compensation for real-time streaming applications in P2P networks. SDHT framework includes an One-hop DHT implementation solution Enhanced Event Detection and Reporting Algorithm (EDRA+) and a distributed Index Mapping and Management Mechanism (DIMM). We conduct intensive simulation experiments based on OverSim to validate the effectiveness of SDHT and evaluate its performance. Numerical results show that SDHT can significantly improve the searching efficiency and media data availability for live streaming applications, with a low overhead.

Index Terms—Internet, peer-to-peer (P2P), live streaming, one-hop DHT.
