Abstract
The banyan network is a popular and basic structure of the multi-stage ATM switches. This paper presents a novel approach to resolve the internal blocking of the banyan network by using a Non-Blocking Permutation Generator (NBPG). The NBPG performs two functions, i.e., the first is to extract the conflict cells from the incoming cells and Ole second is to re-assign new input port addresses to the conflict cells. As a result, NBPG generates non-blocking I/O permutations. To estimate the performance of the NBPG, we provide the results of several simulations.
