CDN互联互通架构与关键技术探讨

Discussion on the Interconnect Architecture and Key Technologies of CDN

从CDN互联互通的需求出发,分析互联互通必须满足的条件,并以IETF CDNI为例,说明CDN互联互通的总体架构,然后进一步分析互联互通涉及的内容统一标识技术、路由请求、稳定性等关键技术,并提出建议方案。

This paper analyzes the requirement of CDN interconnect; then it describes the CDN inter- connect architecture from the example of IETF CD- NI; finally it discusses the key technologies used in CDN interconnect, such as UnicontentID, Request Routing, robust, and gives some proposals on how to use them.
