Abstract :
An input queuing type switching architecture that uses a high-performance contention resolution algorithm to achieve high-speed and large-capacity cross-connect switching is presented. The algorithm, called the time reservation algorithm, features time scheduling and pipeline processing. The performance of this switch is evaluated by computer simulation. The throughput of this switch is about 90%, without requiring high internal operation speeds. Three LSI designs are developed to verify the feasibility of the high-speed switch. They are the input buffer controller LSI, the contention-resolution module LSI, and the space-division switching LSI. The LSIs were constructed with an advanced Si-bipolar high-speed process. Also, 8×8 cross-connect switching boards are introduced. The measured maximum port speed is 1.55 Gb/s
