ABSTRACT:
In one embodiment, an apparatus comprises logic for optimizing network resources usage. The logic is operable to store IGP information, where the IGP information includes a set of attribute values associated with each of a set of content servers. When the logic receives a request for content from a remote peer, the logic determines one or more content servers that can provide the requested content. The logic then retrieves, from the IGP information, a plurality of attribute values associated with a non-looping path from each of the one or more content servers. For each of the one or more content servers, the retrieved attribute values include: one or more capacity values indicating capacities of one or more communication links on the non-looping path from that content server; and one or more utilization values indicating utilizations of the one or more communication links on the non-looping path from that content server. The logic then selects a content server based on the retrieved attribute values, and causes the request for the content to be sent to the selected content server.
