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:
Provided are computer-implemented methods and systems for performing media resource storage and management. The computer-implemented method and system implemented as a request manager is capable of monitoring requests for media resources in a content delivery network. For each monitored request, the request manager determines whether to generate a multifile for the requested media resource. For example, the request manager can first determine whether the media resource is eligible for multifile generation. If eligible, the request manager then determines whether the media resource has reached a popularity threshold. If the media resource has reached the popularity threshold, the request manager initiates generation of the multifile for the requested media resource. Generally, the generated multifile is stored in a storage system associated with the content delivery network.
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-aware 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 determine the particular server's own measured load; convert the particular server's own measured load to a corresponding own particular load category of a plurality of load categories; provide the particular server's own particular load category to other servers of the plurality of servers; obtain load category information from other servers of the plurality of servers; and maintain, as an indication of server load of each of the plurality of servers, the particular server's own particular load category and the load category information from the other servers.
Abstract:
Embodiments herein include methods and systems for use in delivering resources to a client device over a local network. An exemplary system comprises a plurality of caching devices operable to cache resources on behalf of a plurality of content providers, and a local caching device communicatively situated between an access network and the client device, wherein the access network is communicably situated between the plurality of caching devices and the local caching device. The local caching device is operable to retrieve a requested resource from at least one of the plurality of caching devices, deliver the requested resource to the client device over the local network, and store the requested resource for future requests by other client devices.
