The invention comprises a method and apparatus for determining a delay of a link between switches. Specifically, the method comprises determining a plurality of intra-switch router delays by determining an intra-switch router delay between a pair of routers for each pair of routers in a plurality of pairs of routers wherein each of the pairs of routers is connected to one of the first switch and the second switch, determining a plurality of inter-switch router delays by determining an inter-switch router delay between a pair of routers for each pair of routers in a plurality of pairs of routers wherein each of the pairs of routers comprises a first router and a second router, and computing the average delay of the link between the first switch and the second switch using the plurality of intra-switch router delays and the plurality of inter-switch router delays.
