Paper Abstract

This paper presents a novel multibuffer-shared ATM switching architecture based on optical interconnects and optoelectronic hybrid crossbar modules. The core of this switching architecture is the 16 X 16 CMOS-SEED crossbar switching module, and the optical interconnects between the input interface and switching core provide high-speed data paths. Many buffers placed in an output module of the interface are partial shared, which take advantages of output buffer and shared buffer, so these buffers are used more effectively than the output buffer. And these shared buffers bring an advantage that the speed of the accessing each of these buffers is not need very high due to these buffers can write/read many cells in a parallel way. The performance of this ATM switching system is analyzed under the uniform traffic and bursty traffic. The simulation results show that the cell loss probability of this ATM switching system is less than 10e-9 under the uniform traffic with 12-cell length of each shared- buffer, and the cell loss probability is less than 10e-9 under the bursty traffic with 160-cell length of each shared-buffer.
