Abstract
According to one exemplary embodiment, a method for determining the forward and reverse available capacity or tight link capacity of an IP path from a single endpoint includes the steps of: transmitting, from a source IP endpoint node toward a destination IP endpoint node, a forward packet train including a first plurality of IP test packets over the forward IP path; and receiving, at the source IP endpoint node, a corresponding reverse packet train from the destination IP endpoint node, the reverse packet train including a second plurality of IP test packets over the reverse IP path each of which correspond to a respective one of the first plurality of IP test packets. For those IP path capacity measurements embodiments which are TWAMP-based, no changes are needed to the TWAMP control protocol, e.g., since exemplary embodiments make use of padding octets to transfer additional information which can be used for available IP path capacity and tight IP link capacity calculations.
