Abstract: A method for enabling collaboration between an internet service provider (ISP) and another entity includes: gathering a domain name system (DNS) query; evaluating the DNS query wherein the evaluating comprises collecting candidate hosts suitable for delivering content in accordance with the DNS query; ranking the candidate hosts collected by the ISP; providing a first list of the ISP-ranked candidate hosts; forwarding the DNS query to the another entity; evaluating the DNS query wherein the evaluating comprises collecting candidate hosts suitable for delivering content in accordance with the DNS query; ranking the candidate hosts collected by the another entity; providing a second list of the another entity-ranked candidate hosts; matching the first list and the second list; and providing a matched list of ranked candidate hosts. The another entity is a content distribution system (CDN) or another ISP.

Abstract: A method of engineering traffic within a network includes configuring and controlling routing within the network and steering traffic through the network, wherein the steering of the traffic through the network is optimized based on routing control and configuration by evaluating interior gateway protocol weights, label switch paths within multiprotocol label switching and/or border gateway protocol properties. The method further includes obtaining an ingress point at which content enters the network and obtaining an egress point at which content exits the network. The steering of the traffic through the network is optimized based on routing control and configuration by evaluating the ingress point and the egress point.
