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 content delivery network (CDN) includes a control core; and a plurality of caches, each of said caches constructed and adapted to: upon joining the CDN, obtain global configuration data from the control core; and obtain data from other caches. Each of the caches is further constructed and adapted to, having joined the CDN, upon receipt of a request for a particular resource: obtain updated global configuration data, if needed; obtain a customer configuration script (CCS) associated with the particular resource; and serve the particular resource in accordance with the CCS.

Abstract: A method includes monitoring the operational status of at least some name servers in a name server network. Based on the monitoring, when an error or anomalous condition is detected at a particular name server, creating a policy to indicate the status of the particular name server. The policy is taken into account when resolving hostnames using the name server network.

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 network includes a first tier of servers, a second tier of servers and a third tier of servers. The first tier of servers comprises a plurality of primary servers capable of responding to requests. The plurality of primary servers includes at least one dynamic server having a load share characteristic that is dynamically altered during a first period in time and at least one static server having a constant load share characteristic during the first period in time. The second tier of servers includes at least two first layer overflow servers. Each of the first layer overflow servers is configured to provide response duties in the event that one or more of the primary servers is unavailable or overloaded. The third tier of servers comprising at least two second layer overflow servers. Each of the second layer overflow servers is configured to provide response duties in the event that one or more of the primary servers is unavailable or overloaded and one or more of the first layer overflow servers is unavailable or overloaded.
