内容分发网络技术的比较与分析

Analysis and Comparison of Contents Distributed Network Technology

对内容分发网络技术中的CDN技术与集群服务器、W eb缓存技术进行比较和分析,对现有的CDN模式的局限性提出了几点改进的建议。并通过系统模拟表明,改进后的CDN网络可以进一步提升DNS的性能,降低网络管理成本并节约带宽。

In this paper,that mainly to comparison and analysis about CDN technology of content distribution network with Cluster Server and Web cache technology, as well as the existing limitations CDN model put forward several recommendations for improvements, and through the improved system simulation shows that the CDN net-work can be further enhanced DNS performance, reduce network management costs and save bandwidth.
