Abstract:
1. A method for determining a forward and reverse available capacity or tight link capacity of a path from a single endpoint, comprising: transmitting, from a source endpoint node toward a destination endpoint node, a forward packet train including a first plurality of test packets over the path, in a forward direction, at a first rate; receiving, at said source endpoint node, a corresponding reverse packet train from said destination endpoint node, said reverse packet train including a second plurality of test packets over the path in a reverse direction, each of the test packets in the second plurality corresponding to a respective one of said first plurality of test packets; and providing, by said source endpoint node, a reverse packet field in at least one of said first plurality of test packets, wherein the reverse packet field informs said destination endpoint node about an inter-packet time interval at which to transmit said second plurality of test packets, wherein said inter-packet time interval is indicative of a second rate different from said first rate.
