Abstract:
1. A method of measuring traffic at a node under test in a network, comprising: a) sending a plurality of first type datagrams from a source node, each first type datagram having a path through the network including the node under test, each first type datagram causing the node under test to generate a second type datagram, and each second type datagram having a path through the network that includes the source node; b) processing at least two of the second type datagrams to determine a number of datagrams processed by the node under test between the at least two of the second type datagrams; c) determining the time between the at least two of the second type datagrams; and d) computing a traffic value reflecting the ratio between the determined number of messages and the determined time wherein causing the node under test to generate a second type datagram includes setting a time to live field in the first type datagram that causes the datagram to expire upon reaching the node under test.
