Abstract:
1. In a content router associated with a first content distribution network, wherein the content router is a primary content router and the first content distribution network is a primary content distribution network in a peering relationship with a second content distribution network, a method for processing domain resolution requests, the method comprising the steps of: receiving a domain resolution request, wherein the domain resolution request is an original domain resolution request that contains an original domain specification; determining if a content request associated with the domain resolution request is to be processed by the first content distribution network; determining that content associated with the original domain specification is to be obtained from the second content distribution network, and selecting a forward domain specification associated with the second content distribution network; if the content request associated with the domain resolution request is to be processed by the first content distribution network, responding to the domain resolution request with an address resolution response associated with a content engine within the first content distribution network; and if the content request associated with the domain resolution request is not to be processed by the first content distribution network, responding to the domain resolution request with an alternative domain resolution response associated with a second content distribution network, wherein the alternative domain resolution response comprises a forward domain resolution response containing the forward domain specification that causes a device in the second content distribution network to receive a domain resolution request containing the forward domain specification.
