Abstract/Artist's Statement

Through the study of network characteristics it is possible to predict the overall behavior of network traffic, an aim which has significant implications with respect to network scheduling, traffic shaping, congestion control, and flow control. One of these characteristics is the delay that packets experience in the output queue of routers along the network path. This project attempts to implement and verify an untested scheme for measuring queueing delay in the single-hop case. The scheme uses a pair of probing packets, and estimates queueing delay by measuring the intra-probe gap between them after they traverse the router under test. Applications were created to test this scheme both in simulation and on a closed physical network. The scheme was verified in simulation, and, when tested on the physical network, probing packets experienced the gap compression that indicates queueing delay. However, due to a failure to generate stable queuing at the output interface of the router, and the inability to measure intermittent queueing from the router’s console, these results are ultimately inconclusive.
