Abstract:
1. A method of measuring transmission capacity from a first node to a second node through a communication network, the method comprising repeatedly transmitting first and second probe messages, having respective first and second amounts of data from the first node to the second node, wherein one of the first and second amounts exceeds a fragmentation threshold of the communication network, and the other of the first and second amounts is less than or equal to the fragmentation threshold; repeatedly measuring first and second round trip time durations between transmission of the first and second probe messages from the first node and reception back at the first node of first and second response messages from the second node to the first and second probe messages respectively; computing the transmission capacity based on the first and second amounts of data in the probe messages being different and from a difference between first and second minimal values of the first and second round trip time durations, respectively.
