For a network that connects several computers, a method of determining the network bandwidth between two computers. The method measures a first time interval between when one of the computers (1) sends a first data set to the other computer and (2) receives a first response. It also measures a second time interval between when one of the computers (1) sends a second data set to the other computer and (2) receives a second response. The method then identifies the network bandwidth from the two measured time intervals.
