摘要
传统Internet的尽力而为服务无法满足用户对视频传输的高带宽需求及严格的QoS保证[1]。本文在分析了区分服务体系结构及其各部分功能模块的基础上,给出了一种基于IP区分服务的MPEG视频分组标记算法,并进行了仿真实验和性能分析,结果表明这种对MPEG不同类型的帧以不同的PHB方式来调度转发的机制是有效的。
With the rapid development of the multimedia technology, the traditional Internet,which provides Best-Effort services, cannot meet users' requirements of high bandwidth and stringent QoS guarantee for transmitting MPEG videos. The architecture of Differentiated Services model is analyzed and its each function model is simply introduced in this paper, and then a MPEG video packet marking algorithm is put forward.Finally the simulation results and performance analysis show that the the proposed approach is effective and the different PHB is scheduled and forwarded aimed to different frame of MPEG video.
