Abstract
Mechanisms and techniques operating in a content distribution network in a peering relationship with a second content distribution network. The system maintains a first client list identifying a first set of client devices associated with a first content distribution network. The system also obtains a second client list identifying a second set of client devices associated with a second content distribution network. The system applies a client list filtering technique to the first client list and the second client list to produce a preferred client list associated with the second content distribution network. The preferred client list potentially identifies at least one preferred client device for which the second content distribution network preferably processes client requests. The system then operates a content routing technique to direct a client request associated with a client device to a content distribution network having a preferred client list that identifies the client device associated with the client request as a preferred client device.
