    • A method for Internet content delivery in a content delivery network established at network locations, the content delivery network comprising a plurality of content servers for serving content resources. The plurality of content servers includes a plurality of subsets of content servers, each subject being located at one of a plurality of Internet data centers. For each Internet Protocol (IP) address block from which requests for content resources are expected to be received, the method generates a candidate list of Internet data centers to be used to service the requests for content resources. For the IP address block, the method selects at least one of the Internet data centers from the candidate list to be used to service the requests for content resources. The selected Internet data center for the IP address block is written into a network map. The selecting step is carried out concurrently for each IP address block from which requests for content resources are expected to be received such that the network map comprises the selected Internet data center for each IP address block. The network map is then provided to a domain name service (DNS) associated with the content delivery network. In response to a DNS query received at the domain name service associated with the content delivery network, the network map is used to identify one of the Internet data centers from the candidate list to be used to service a request for a content resource.
    • 一种用于在网络位置处建立的内容传送网络中的因特网内容传送的方法,所述内容传送网络包括用于服务内容资源的多个内容服务器。 多个内容服务器包括多个内容服务器子集,每个主题位于多个因特网数据中心之一。 对于期望从其接收对内容资源的请求的每个因特网协议(IP)地址块,该方法生成用于服务对内容资源的请求的因特网数据中心的候选列表。 对于IP地址块,该方法从候选列表中选择至少一个因特网数据中心来用于服务于内容资源的请求。 所选择的IP地址块的Internet数据中心被写入网络映射。 对于期望从其接收内容资源的请求的每个IP地址块同时执行选择步骤,使得网络映射包括用于每个IP地址块的所选择的因特网数据中心。 然后将网络地图提供给与内容传送网络相关联的域名服务(DNS)。 响应于在与内容传送网络相关联的域名服务处接收的DNS查询,网络地图用于从候选列表中识别要用于为内容资源的请求服务的候补列表中的一个。
