Abstract: A method and storage medium having computer-executable instructions stored thereon estimate traffic contract parameters in an asynchronous transfer mode (ATM) network. The method and the computer-executable instructions include: generating data for ATM cell packet arrival times of a number of cells received for a predetermined period of time; determining a sustained cell rate (SCR) parameter; determining the PCR parameter; generating PCR leaky bucket data and SCR leaky bucket data; determining a cell delay variation tolerance parameter (CDVT) utilizing the PCR leaky bucket data; and determining a maximum burst size (MBS) parameter utilizing the SCR leaky bucket data.

Abstract: Method and apparatus for analyzing intra-cell delay times. The delay time between cells is measured and the number of times the measured delay times equals each of a plurality of predefined values is calculated. A graph is displayed indicating the count for each of the plurality of predefined values.
