Abstract

Burst switching research in dispersed control and integrated switching is described. Burst transport is integrated in that voice and data are switched through the same switching fabric and transmission media. Burst switching is compared to and distinguished from fast packet, fast circuit, and ATM (asynchronous transfer mode) switching. Misunderstandings about burst transport that have appeared in the literature are corrected, to wit: burst does not immediately clip in case of channel contention; burst switches voice and data in the same way; and a burst switch interfaces naturally to other types of switches. Round-trip delay performance is calculated to be less than 5 ms. The current status of the burst project is described
