Abstract

A method of and program for dynamically testing a buffering and selection device, wherein the buffering and selection device receives a transmission at an average bandwidth of T and in peak bandwidth bursts that may be greater than T, are provided. The buffering and selection device transmits data to one or more receive devices, all of which have a total average bandwidth of at least T. The buffering and selection device has buffers apportioned to each receive device in order to store data that is written in burst mode destined for that receive device. The method includes disabling the output data flow to the receive device being tested and then generating input data to the buffering and selection device tagged for each receive device in burst mode at a preselected number of transfers for each receive device. The program determines when the preselected number of transfers has occurred and then enables data flow to the receive device being tested. It is then determined if output to each receive device has commenced within a preselected latency period, and, if it has, it is determined if the preselected number of transfers of data has occurred within a preselected transfer period, i.…
