The document discusses two types of multistage interconnection networks: the Banyan network and the Omega network. The Banyan network uses a shuffle right inter-stage connection pattern, where nodes are connected from one stage to the next by routing to the right. The Omega network uses a shuffle left inter-stage connection pattern, where nodes route to the left between stages. Examples are given of how data would route through each network from processors to memories.
