Claim One:
1. A method of estimating intra-mode paths, the method comprising the steps of: receiving in memory at least a partial autonomous system (AS)-level path comprising a first AS and a second AS, the at least partial AS-level path corresponding to a mode of communication between a first endpoint and a second endpoint; selecting by a processor a first hand off pair comprising an exit point from the first AS and an entry point into the second AS, the exit point being in communication with the entry point, the selection being based on, at least in part, at least one of: (i) a property of the first AS, (ii) a property of the second AS, and (iii) a statistical property of traffic associated with at least one of a proxy to the first endpoint and a proxy to the second endpoint, the traffic passing via the first AS; and identifying by the processor a set of router-level paths within the first AS, from a first entry point into the first AS to the exit point from the first AS within the first hand off pair.
