This document summarizes different types of indirect (dynamic) networks including crossbar networks, multistage interconnection networks (MINs), nonblocking networks, rearrangeable nonblocking networks, and blocking networks. It describes the characteristics of different MIN topologies like Clos networks, Benes networks, Omega networks, baseline networks, indirect binary n-cubes, and bidirectional networks. It also covers topics like fault tolerance in MINs, hybrid networks, the history of Clos networks and indirect networks, and applications in telephone switching and processor-memory networks.
