Abstract: The duration of cache writing is always long in the segment-based cache. To holding the cache proxy server performance, this paper limits the writing bandwidth by judge method of writing bandwidth and introduces several judge methods. Testing results show that these methods have the capability of keeping cache effect and reducing writing workload.

Key words: streaming media, proxy cache, segment-based cache, writing bandwidth limitation

摘要： 在分段缓存中，缓存写入操作的持续时间通常较长。为保证缓存代理服务器的服务性能，在分段缓存技术中利用写入带宽判断方法限制实时写入带宽，介绍典型的写入带宽判断方法。模拟测试结果证明，此类方法具有保证缓存效果和降低缓存写入负载的能力。
