Approximate analysis of the end-to-end delay in ATM networks

A very general approach for an approximate analysis of end-to-end delay jitter in asynchronous transfer mode (ATM) networks for bursty input traffic is presented. Since the cell loss requirements within ATM networks are very restrictive, interest is in the tail of the complementary probability distribution function of the end-to-end delay to estimate the cell loss probability at the reassembly buffer. An analytical approach for an isolated network node as well as for a whole reference connection is presented. The approximation results are in good agreement with simulation results and indicate that the end-to-end delay jitter is in the range of the maximum transfer delay of one queuing node, if the bursty input traffic is controlled by adequate traffic control mechanisms
