摘要
提出了适用于点播系统的推拉结合的内容分发方案,该方案通过对调度窗口的划分,解决了方案中存在较多冗余数据的问题,同时通过调度带宽的动态调整和片段预定的转移,使得所提方案更加适应于高动态性及缓存不连续的点播环境。
The dissertation proposes a push-pull combination content distribution strategy for VOD systems.Through dividing of the scheduling buffer,the proposed scheme overcomes the problems of redundant packets.At the same time,the dynamically adjusting the scheduling bandwidth and the migration of fragment-orders make the more responsive to dynamic demand systems and for the condition of discontinuous buffer at peers.
