Abstract
In an application of P2P streaming media system, the performances of playback continuity and startup latency have been regarded as the most important two metrics intuitively. However, the rarity and urgency of data block is not considered when the popularity of data block is calculated in the traditional scheduling strategies. That leads to the inferior playback continuity and startup latency. To overcome the drawbacks of the traditional scheduling strategies, this paper presents a new scheduling strategy based on Cache Offset (BCOP), which deals with the rarity and urgency of data block simultaneously. In the proposed BCOP strategy, the drawbacks mentioned above have been solved well by means of counting and processing the information about the cache offset of playback of requested data block and the two metrics have been improved noticeably. The results of experiments demonstrate the effectiveness of the proposed strategy in terms of higher continuity and lower startup latency.
