    Abstract: A computer-implemented method, in a content delivery (CD) network, wherein the CD network delivers content on behalf of multiple content providers. At a server in the CD network, wherein the serving is processing multiple requests from a plurality of distinct clients, and based on utilization of at least one capacity of the server, degrading processing of a first at least some of the requests. The server may continue to accept incoming requests while degrading processing of some requests. While processing of any requests is degraded, at least some new incoming requests may also be degraded. Based on the utilization of the at least one capacity of the server, a request may be un-degraded.

    Abstract: A computer-implemented method, operable on a device in a content delivery network (CDN), wherein the CDN delivers content on behalf of at least one content provider, the device implementing a content delivery (CD) service, the method includes, by the service on the device: receiving a request for a particular resource from a client; determining whether the client includes an optimization support mechanism; when the client includes an optimization support mechanism, providing the client with a first version of the particular resource, optimized, at least in part, for the capabilities of the client in combination with the optimization support mechanism; otherwise providing the client with either (i) an un-optimized version of the particular resource, or (ii) a version of the particular resource optimized, at least in part, for the capabilities of the client without the capabilities of the optimization support mechanism.

    Abstract: A computer-implemented method in a content delivery network (CDN) having multiple delivery servers. The CDN delivers content on behalf of at least one content provider. Distinct delivery servers are logically grouped into delivery server groups. One or more CDN name servers are associated with some of the delivery server groups. Network map data are determined using network data determined by the CDN name servers associated with at least some of the deliver server groups. The network data with respect to a CDN name server relative to a resolver is based on an estimated popularity of that CDN name server for that resolver. Responsive to a client request, including a hostname associated with a content provider, at least one CDN name server determines, using network map data, at least one delivery server to process the client request.
