METHOD FOR EVALUATING LINK COST METRICS IN COMMUNICATION NETWORKS
First Claim
1. Method for measuring link cost metrics and evaluating their accuracy with respect to reference measure of link quality in a communication network, said method comprising the steps of:
- during a given time interval, simultaneously transmitting several types of probe packets and data traffic, and estimating a plurality of link cost metrics (metricA, metricB, . . . , metricN) and a reference measure of link quality for a set of communication links;
evaluating the accuracy of the estimated link cost metrics (metricA, metricB, . . . , metricN) by computing their correlation with the reference measure of link quality; and
collecting cross-layer information for each probe packet.
