Abstract: A first group is defined from an arbitrary set of nodes comprising service instances. Each node in the first group assumes one or more responsibilities in processing a request across the first group. A second group is defined from an arbitrary set of nodes. Each node in the second group assumes one or more discrete responsibilities in processing a request across the second group. The second group has a topology distinct from that of the first group. Request processing is transitioned from the first group to the second group based on a responsibility adaptation policy.

Abstract: A computer-implemented method is operable on a device having hardware including memory and at least one processor. The method includes maintaining invalidation information in a list at a service on the device, where the invalidation information includes a plurality of invalidation commands. At least some of the invalidation commands in the list are selectively combined to form at least one other invalidation command in the list.

Abstract: In a content delivery network (CDN a method includes: receiving a request for a CDN service of a particular type, wherein a CDN service of said particular type defines a fixed number of configurable layers of request processing, sequentially from a first layer to a last layer; and processing said request, starting at said first layer, said processing being based on a modifiable runtime environment, said processing continuing conditionally through each of said layers in turn until either said request is terminated by one of said layers or said last layer processes said request. A layer may cause some of the processing of a request to be handled by another service. The CDN service may be selected from: delivery services, collector services, reducer services, rendezvous services, configuration services, and control services.

Abstract: In a content delivery framework including a network with multiple delivery service endpoints running on devices, the multiple service endpoints forming a plurality of sub-clusters, a group is defined from a set of nodes comprising delivery service instances across the devices of the plurality of sub-clusters. Each node in the group assumes one or more discrete responsibilities involved in processing of a request across the group, the discrete responsibilities including being fill-responsible. A fill-responsible node is selected from the group to be responsible for processing a request made at a node of the group, the request relating to a particular resource. Selection of the fill-responsible node is based on the particular resource, and the fill-responsible node is selected from a set of one or more nodes in the group that are fill-responsible for the particular resource, the set being defined based on a policy associated with the particular resource.
