Abstract:
A computer-implemented method operable in a content delivery service (CDN), includes, by a collector system: receiving multiple event streams of event data, said multiple event streams comprising event data from a plurality of CD services in said CDN, each event of said event streams comprising: (i) a timestamp for said event, (ii) information relating to said event; and producing state data relating to information represented in said event data of said multiple event streams while being able to asynchronously respond to queries relating to said state data.
Abstract:
A content delivery network (CDN) includes a single autonomous CDN partitioned into multiple virtual CDNs, the multiple virtual CDNs being organized into a CDN hierarchy. Each virtual CDN is allocated separate physical resources. Within the CDN hierarchy, at least one parent virtual CDN has at least one child virtual CDN. A parent virtual CDN grants at least one privilege to at least one child virtual CDN.
Abstract:
A method in a content delivery framework includes, at a first service, receiving invalidation information relating to at least one resource; invalidating the at least one resource; and then, when the at least one resource has been invalidated at the first service, providing first information about the invalidating to a collector system. At a second service distinct from the first service, receiving the invalidation information relating to the at least one resource; invalidating the at least one resource at the second service; and then, when the at least one resource has been invalidated at the second service, providing second information about the invalidating at the second service to the collector system.
Abstract:
A method includes maintaining first and second mapping data. The first mapping data is from canonical names (CNAMEs) to binding names (BNAMEs), and the second mapping data is from BNAMEs to address information. The method includes using the first mapping data to map a canonical name to a binding name; and then using the second mapping data to map the binding name to corresponding address information.
Abstract:
A method is operable in a network comprising multiple service endpoints, the service endpoints running on a plurality of devices, wherein the multiple service endpoints form one or more sub-clusters. The method includes defining a group from an arbitrary set of nodes comprising service instances across the machines of the one or more sub-clusters, wherein each node in the group assumes one or more discrete responsibilities involved in processing of a request across the group. In response to a request made at a node the group, the service type of the request is dynamically determined; and, based on the type of the request, one or more nodes in the group are selected to be responsible for processing the request.
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:
A device supporting content delivery is configured to run at least one content delivery (CD) service of a plurality of CD services. The plurality of CD services include delivery services with dynamically configurable log information.
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:
A device supporting content delivery is configured to run at least one content delivery (CD) service of a plurality of CD services. The plurality of CD services include rendezvous services.
