ABSTRACT:
According to one aspect, the subject matter described herein comprises methods, systems, and computer program products for performing IP link proving using heartbeat messages. The method includes transmitting a plurality of heartbeat messages over an IP communications link. A transmission parameter of the plurality of heartbeat messages is varied and a plurality of heartbeat acknowledgement messages corresponding to at least a subset of the plurality of heartbeat messages is received. A measure of processing capabilities of the IP communications link is determined based on the transmission parameters and the heartbeat acknowledgement messages.
