Abstract
A method for discovering a cross-domain link between ports in a network implements different compensation algorithms based on differences in the intervals used to obtain traffic flow information at the ports. A first compensation algorithm discovers the cross-domain link when the intervals have different sizes. A second compensation algorithm discovers the cross-domain link when the intervals are misaligned. The algorithms may be implemented by a cross-domain coordinator which recites count information from network devices that include the ports.
