摘要： A content delivery network has at least a first tier of servers. A content delivery method includes, at a first server in the first tier of servers, obtaining a request from a client for a resource. If the resource is available at the first server or at a peer of the first server, then the resource is served to the client from the first server. Otherwise, it is determined whether the resource is popular, and if the resource is determined to be popular, then the first server obtains the resource and the first server serves the resource to the client. If the resource is determined not to be popular, the client is directed to a second server, not in the first tier of servers, and the second server serves the resource to the client. The second server may be in a second tier of servers or it may be an origin server.
摘要翻译：内容传送网络至少具有第一层服务器。内容递送方法包括在第一层服务器中的第一服务器处，从客户端获取资源的请求。如果资源在第一个服务器或第一个服务器的一个对等体上可用，则资源从第一个服务器提供给客户端。否则，确定资源是否流行，如果资源被确定为流行，则第一服务器获得资源，并且第一服务器向客户端提供资源。如果资源被确定为不受欢迎，则客户端被引导到第二服务器，而不是在第一层服务器中，并且第二服务器向客户端提供资源。第二服务器可以在第二层服务器中，或者它可以是源服务器。

摘要： A computer-implemented method, operable in a content delivery network (CDN) including a plurality of cache servers and domain name servers. At a cache server in the CDN, a first domain name is obtained, the first domain name being associated with a client request for a resource from the cache server. One or more values associated with the client request are determined and a second domain name is generated, including information from the first domain name and information relating to the one or more values associated with the client request. The second domain name is provided to the client.

摘要： A load-balancing cluster includes a switch having a plurality of ports; and a plurality of servers connected to at least some of the plurality of ports of the switch. Each server is addressable by the same virtual Internet Protocol (VIP) address. Each server in the cluster has a mechanism constructed and adapted to respond to connection requests at the VIP by selecting one of the plurality of servers to handle that connection, wherein the selecting is based, at least in part, on a given function of information used to request the connection; and a firewall mechanism constructed and adapted to accept all requests for the VIP address for a particular connection only on the server that has been selected to handle that particular connection. The selected server determines whether it is responsible for the request and may hand it off to another cluster member.
摘要翻译：负载均衡集群包括具有多个端口的交换机; 以及连接到交换机的多个端口中的至少一些端口的多个服务器。每个服务器可由相同的虚拟互联网协议（VIP）地址寻址。集群中的每个服务器具有构造并适于通过选择多个服务器中的一个来处理该连接来响应VIP处的连接请求的机制，其中，所述选择至少部分地基于所使用的信息的给定功能请求连接; 以及防火墙机制，其构造和适于仅在已经被选择来处理该特定连接的服务器上接受针对特定连接的VIP地址的所有请求。所选择的服务器确定它是否对请求负责，并将其移交给另一个集群成员。
