Solution for packet switching of broadband ISDN

A possible solution for the broadband ISDN is proposed. A new packet switch, denoted by DPPS (double phase packet switch), is found to be capable of performing well with low cost. DPPS consists of several baseline networks in parallel. DPPS is modular and can easily be expanded because of the recursive structure of baseline networks. Along with the simple and distributed control algorithm, the DPPS can be implemented in VLSI and is consequently high speed and high capacity. Analysis results show that DPPS is able to achieve good throughput-delay performance even under heavy traffic loads.<>
