Research on coordination strategy of introducing internet content by Cache, CDN and IDC

目前,在各大运营商的网络中,普遍存在Cache、CDN、IDC引入三种内容提供方式。这三种方式实现的机制不同,对网络的提升效果不同,对运营商、ICP的影响也不同,如何实现三种方式的有效协同,最大化的提升网络性能,成为各大运营商需要重点考虑的问题。对三种内容提供方式进行多维度分析研究,提出协同策略,从而指导网络建设及运营。

At present, among the major carriers networks, there are three ways including Cache, CDN, IDC tointroduce internet content by providers.These three ways are with different mechanisms, differenteffects of enhancening networks and impacting different carriers, ICP providers. How to achieveeffective coordination of three ways to maximize network performance enhancement has become animportant consideration major to carriers . In this paper, the contents introduce three ways to providemulti-dimensional analysis of proposed collaborative strategy to guide the construction and operationof the network.
