Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A content delivery network (CDN) includes multiple cluster sites, including sites with streaming media servers, caching servers and storage devices accessible to the caching servers for storing streaming content. Interface software is configured to initiate retrieval, by a caching server, of electronic streaming resources from the one or more storage devices in response to requests for the electronic streaming resource received by the streaming media server.

Abstract: A load-balancing cluster includes a switch having ports; and servers connected to at least some of the ports. The servers are each addressable by the same virtual Internet Protocol (VIP) address. A first server of the plurality of servers establishing a Transmission Control Protocol (TCP) connection with a client computer, and, in response to a resource request received by the first server from the client computer for a particular resource, if the first server does not have a copy of the particular resource it queries one or more peers regarding the particular resource. Based at least in part on responses from the peers, the first server either: obtains the particular resource from a peer; or migrates the TCP connection to a peer; or serves the particular resource to the client request through a second server.

Abstract: Provided are methods and systems for dynamic binding in the context of content delivery. For example, the methods and systems may be implemented as a dynamic binding process that maps a content provider to a first set of content servers in a content distribution network. The dynamic binding process may then facilitate the content to be received from the content provider so that the content can be distributed by the first set of content servers in the content distribution network. The dynamic binding process further monitors network traffic associated with the content from the content provider and determines at least one metric associated with the network traffic. Additionally, the dynamic binding process can remap the content provider to a second set of content servers in the content distribution network based on at least one of the metrics.

Abstract translation: 提供了在内容传递的上下文中用于动态绑定的方法和系统。 例如，方法和系统可以被实现为将内容提供商映射到内容分发网络中的第一组内容服务器的动态绑定过程。 动态绑定过程然后可以便于从内容提供商接收内容，使得内容可以由内容分发网络中的第一组内容服务器分发。 动态绑定过程进一步监视来自内容提供商的与内容相关联的网络流量，并且确定与网络流量相关联的至少一个度量。 另外，动态绑定过程可以基于至少一个度量来将内容提供商重新映射到内容分发网络中的第二组内容服务器。
