Bodhi: A Highly Modular Terabit ATM Switch Fabric Architecture

摘要

In this paper, we propose a high performance highly modular ATM switch architecture known as Bodhi which is suitable for small, large, and very large size ATM switch im- plementations. Its basic configuration consists of two stages: an input stage and an output stage. The input stage consists of input group modules (EGMs) and output stage output group modules (OGMs). Each IGM-OGM pair is connected by multi- ple paths which carry cells from IGMs to OGMs. Excess cells at the IGMs are recycled to minimize the cell loss probability.
