摘要: 在内容分发网络基础上,提出一个针对动态Web应用的数据库缓存应用模型。该应用模型采用内容无关缓存和部分复制的机制,通过内容无关缓存方法、基于主从协议模型的缓存一致性策略和基于相似关系的空间聚类算法等,可满足多种动态Web应用加速的需求。实验结果表明,该方法可有效地提高系统负载量,改善用户体验,抵御洪水用户的侵袭。

Abstract: A scheme combining data cache with partial replication based on Content Distribution Network(CDN) is proposed in order to find an accelerated scheme appropriate for various Web applications. The scheme adapts to various Web applications dynamically by way of cache coherency strategy based on master-slave protocol model and spatial clustering algorithm using correlation-based similarity. Experimental result shows that this scheme improves not only throughput of system but also users’ experience. Besides, it can also resist flood crowds efficiently.

Key words: Content Distribution Network(CDN), content blind cache, partial replication, dynamic Web application, master-slave protocol model, spatial clustering
