Abstract
In the current, the structured P2P-based time-shifted streaming system exists the problems that the copy of scalability is bad and the maintenance costs are higher. For resolving the problems, a structured query model based on video block for time-shifted streaming is proposed. By the hierarchy divided according to the first video block in the cache of node and all video block in the cache registered, it makes the routing information reduced which layer node needs to maintain and the problem resolved which the copy of time-shifted streaming can not be fully found. Experimental results show that compared with other model, this model has a better cache hit ratio, better lookup performance and lower maintenance overhead.关键词
