Abstract: A content delivery network (CDN) includes a plurality of CDN components including at least one CDN rendezvous mechanism and at least one control core. The CDN components are controlled by control core data from the at least one control core. Some CDN components obtain CDN resources including control core data from at least some other CDN components. The CDN components use the CDN rendezvous mechanism to select one or more CDN components from which to obtain CDN resources.

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 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. A domain name server in the CDN obtains a request to resolve a first domain name; extracts one or more keys and one or more corresponding values from the first domain name, and generates a second domain name based on the first domain name, the second domain name excluding information from the first domain name relating to the one or more keys and the one or more values. The name server resolves the second domain name using at least some of the one or more values extracted from the first domain name.

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: 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.
