This paper presents a low-cost hardware and software system that can be used to monitor ATM cell flows, and to make absolute measurements of ATM cell arrival times. The system uses a purpose-built ATM cell capture board in a standard LINUX PC, with a GPS time receiver to provide an accurate time reference. The systems can be used locally, or can be operated remotely, sending its results back to a central point over a network connection. As well as cell arrival times, the system computes a 32-bit signature for each cell payload. This enables the recognition of cells in different parts of the network, the measurement of cell transit time, and the detection of cell loss. Results are presented of measurements made on local and wide area ATM networks, and on the intercontinental Internet.
