Method for identifying high traffic origin-destination node pairs in a packet based network

摘要

The present invention provides methods for identifying high traffic origin-destination node pairs in a packet based network and for estimating the mean traffic between the high traffic origin-destination node pairs. High traffic origin-destination node pairs may be identified in accordance with the present invention by modeling the variance of traffic in a static routing environment and identifying the origin-destination node pairs with a high variance as high traffic origin-destination node pairs. For estimating purposes, traffic between low traffic origin-destination node pairs may be assumed to be a predetermined value, such as zero, to reduce the number of variables to estimate. Routing changes necessary to create a full rank routing matrix may be identified and applied to the network, and link utilization information collected under each routing scenario may be used to estimate the mean traffic between the high traffic origin-destination node pairs.
