Multi-stage ATM Switching Systems

This paper proposes a distributed tra・丘・c control method for large multi-stage ATII switching systems・ In the proposed switching system? each port of the basic switches has its own trafBc monitor, and each line unit (LU) periodically obtains COngeStion information about available paths from OA-1工cells in order to route a newvirtual circuit independently・ The perfomance of the proposed system depends on the intervalbetween OA-V cellSl We show how an appropnate intervalcan be determined in order to majdmize the number of user cells that each LU can send.
