| 摘 要： | 片段缓存机制是加速动态网页分发的有效解决方案之一,但是实施片段缓存需要有效的共享片段检测机制。针对这种情况,提出了一种高效的共享片段检测算法,介绍了基于片段缓存的动态网页传送模型。该模型能够自动识别共享片段和有效的缓存单元,更好地消除冗余数据,提高缓存命中率。实验和分析表明,与现有方案ESI和Silo相比,该模型能够有效节约带宽,缩短用户请求的响应时间。

| Abstract: | Fragment-based caching mechanism is one of effective solutions to speed up the delivery of dynamic web pages. However, the implementation of this mechanism needs to be guaranteed by efficient methods to detect shared fragments. A model of efficient delivery of dynamic web pages with fragment-base caching was described. Besides, an efficient shared fragments detection algorithm was proposed. The model is capable of detecting shared fragments, resulting in higher cache hit rates. The experimental results show that the model can provide more bandwidth saving and latency reduction than existing solutions ESI and Silo. |
