Method and apparatus for estimating delay and jitter between many network routers using measurements between a preferred set of routers

摘要

A method and apparatus for determining a network performance metric in a network is described. The network includes a number of network elements and a number of links. Each of the network elements is coupled to at least one other of the network elements by at least one of the links. The method includes forming a first set of network element pairs, ordering a first number of network element pairs, forming a second set of network element pairs, measuring a measured network performance metric between a first network element pair and computing a computed network performance metric.
