Abstract
A system receives a data unit from a sending node and identifies if the data unit indicates that it is a test data unit. The system determines a delta time that includes a difference between a time at which a response data unit is going to be sent to the sending node and a time at which the data unit was received. The system inserts the delta time, if the identification indicates that the data unit is a test data unit, in the response data unit and sends the response data unit to the sending node.
