Abstract: In general, techniques are described for managing content request referrals by keying content requests to a composite key data structure that maps end-user address prefixes and content identifiers to content delivery network servers of downstream CDNs. In one example, a CDN exchange includes a communication module to receive first network prefixes and first content identifiers from a first secondary content delivery network and to receive second network prefixes and second content identifiers from a second secondary content delivery network. A request router of the CDN exchange redirects the content request to the first secondary content delivery network or to the second secondary content delivery network according to a network address of the end user device and a content identifier for the content request.

Abstract translation: 通常，描述了通过将内容请求键入到将终端用户地址前缀和内容标识符映射到下游CDN的内容传送网络服务器的复合密钥数据结构来管理内容请求引用的技术。 在一个示例中，CDN交换机包括通信模块，用于从第一次要内容传送网络接收第一网络前缀和第一内容标识符，并从第二次要内容传送网络接收第二网络前缀和第二内容标识符。 CDN交换机的请求路由器根据最终用户设备的网络地址和内容请求的内容标识符将内容请求重定向到第一次要内容传送网络或第二次要内容传送网络。
