Abstract
In an embodiment, a computer implemented method for determining network delay values comprises receiving, by a management server that is communicatively coupled via one or more networks or internetworks to a first router and a second router, two or more first timestamp values from the first router at first times at which two or more packets associated with a particular packet flow are received at the first router; receiving by the management server two or more second timestamp values from the second router at second times at which the same two or more packets associated with the same particular packet flow are received at the second router; determining one or more of: a one-way delay time in which the particular packet flow travels between the first router and the second router based on the first timestamp values and the second timestamp values; an inferred round-trip time.
