Multi-level peering in a content delivery framework

摘要

A computer-implemented method is operable in a network comprising multiple delivery service endpoints running on a plurality of devices where each of the delivery service endpoints is constructed and adapted to deliver resources. A plurality of the delivery service endpoints comprise a group, wherein each node in the group has at least one kind of responsibility relating to delivery of resources. The method includes receiving a request at a node; and, based on what kind of responsibility the node has for the request, attempting to process the request outside the group.
