    摘要： A method and system of analyzing a network to identify a network defect allows user selection of traffic subset to be recorded. After recording the selected traffic subset of the network traffic during network operation, the recorded traffic is then replayed at least in part to the network to replicate, and thus assist in identifying, the network defect.

    摘要： 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.

    摘要： 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.

    摘要： A method for controlling data communication within a network with multiple interconnected network elements includes: generating a representation of the network; detecting changes in the network and updating the representation of the network; receiving a request from a client network element, wherein the request comprises information which identifies a source network element and at least two destination network elements; determining for each identified destination network element, a ranking value for the communication path between the source network element and the respective identified destination network element based on the representation of the network; generating an ordered list of the identified destination network elements based on the respective ranking values; transmitting the ordered list to the client network element from the central network element; and selecting, based on the ordered list, at least one of the identified destination network elements for data communication with the source network element.
