In a network interconnecting a plurality of content providers and a plurality of clients, for providing content to a client, each of the plurality of content providers is coupled to at least one content distribution network of a plurality of content distribution networks, wherein the client is coupled to at least one of the plurality of content distribution networks and a request for the content is sent from the client to a redirector node that receives requests, wherein a redirector at the redirector node provides an address for a server available to serve the requested content. When the client's content distribution network is a primary content distribution network for the content provider providing the requested content, redirecting the client to a server within the client's content distribution network. When the client's content distribution network is not a primary content distribution network for the content provider but the client's content distribution network has a content peering relationship with a primary content distribution network for the content provider, redirecting the client to a server within the client's content distribution network. When the client's content distribution network is not a primary content distribution network for the content provider and the client's content distribution network does not have a content peering relationship with a primary content distribution network for the content provider, redirecting the client to a server outside the client's content distribution network. The redirecting can be done using a domain name service (DNS) server that responds to requests for domain name resolution that include metadata encoding for the content being requested and / or attributes of the resolution request other than a domain name or explicit client / redirector communication to perform the redirection.

The bypass network is designed to provide fast access and high quality streaming media services anywhere anytime. There are five major components including Peering Gateway, Content Locator, Edge Server, Gateway and Client. The whole bypass network is divided into number of self-managed sub-networks, which are referred as local networks in this document. Each local network contains Edge Servers, gateways, and a Content Locator. The Edge Servers serve as cache storage and streaming servers for the local network. The gateways provide a connection point for the client computers. Each local network is managed by a Content Locator. The Content Locator handles all client requests by communicating with the Peering Gateway and actual web sites, and makes the content available on local Edge Servers. The Content Locator also balances the load on each Edge Server by monitoring the workload on them. One embodiment is designed for home users whose home machine does not move around frequently. A second embodiment is designed for business users who travel around very often where the laptops would self-configure as a client of the network.

Third party cache appliances are configured into a content delivery service to enable such devices to cache and serve content that has been tagged for delivery by the service. The invention enables the content delivery service to extend the reach of its network while taking advantage of high performance, off-the-shelf cache appliances. If the third party caches comprise part of a third party content delivery network, the interconnection of caches to the CDS according to the present invention enables the CDS and the third party network to share responsibility for delivering the content. To facilitate such “content peering,” the CDS may also include a traffic analysis mechanism to provide the third party network with preferably real-time data identifying the content delivered by the CDS from the third party caches. The CDS may also include a logging mechanism to generate appropriate billing and reporting of the third party content that is delivered from the cache appliances that have been joined into the CDS.

Embodiments of a shared resource distributed index mechanism that peers in a peer-to-peer network may utilize to distribute index entries corresponding to resources to indexes of shared resources among one or more other peers. These indexes may be used to direct queries to peers where the queries are most likely to be answered. When a query is received by a rendezvous peer including one or more indexes, contents of the query may be "looked up" in the index to find matches. The results of the lookup may include information on one or peer(s) that may hold advertisement(s) to the resource requested by the query. The query may then be forwarded to one or more peers that may hold the advertisement for the resource. Embodiments may provide "loosely-coupled" distribution of index entries for use in querying for resources in the peer-to-peer network.

Service applications at one or more service providers are bundled through a server thereby creating new services. The server comprises service agents, each of which corresponds to one or more service applications and proxies for its application(s) to perform service bundling. When a subscriber interacts with a service application and affects service specific data, the application sends this data along with the subscriber's intent with respect to this data to the server. The server next identifies a primary service agent, which is the agent proxying for the application. This agent determines a peer group of service agents, wherein each peer agent corresponds to a service application that together define a bundled service. The principal and peer agents subsequently negotiate / coordinate with respect to the service data. As a result, the agents may communicate with their respective service applications to determine a subscriber's current service data configurations and / or to update these configurations.
