  • Publication number: 20190109772
    Abstract: A computer-implemented method in a content delivery (CD) network includes determining at least one pseudo client IP address using first log information and second log information. The first log information being from a rendezvous service in the content delivery (CD) network, and includes at least one resolver IP address associated with at least one first request made at the rendezvous service. The second log information is from at least one probe service in the CD network, and includes at least one client IP address associated with at least one second request to the at least one probe service. The method also includes making an association between (i) the at least one pseudo client IP address and (ii) the at least one resolver IP address; and then, responsive to a name resolution request, the name resolution request including the at least one resolver IP address, the rendezvous service using the at least one pseudo client IP address instead of the resolver IP address to resolve the name.

  • Publication number: 20190065574
    Abstract: Example embodiments herein include a system having one or more edge servers disposed in an edge site of a content delivery network (CDN). The system can include a collector for collecting analytics associated with requests for content in the CDN. One or more additional collectors can be instantiated in the system, for example, in response to an increase in recordable events detected in the CDN. The system can include an aggregator for aggregating the collected analytics with analytics collected from other edge stages of the CDN. The system can also include a data store that stores the aggregated analytics according to a configurable data model.

  • Patent number: 9887885
    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.

  • Patent number: 9749191
    Abstract: In a content delivery network (CDN) a method includes: receiving a request for a CDN service of a first type, wherein a CDN service of the first type defines a fixed number of configurable layers of request processing, sequentially from a first layer to a last layer; and processing the request, starting at the first layer, the processing being based on a modifiable runtime environment, the processing continuing conditionally through each of the layers in turn until either the request is terminated by one of the layers or the last layer processes the 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.

  • Patent number: 9749192
    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.
