Abstract. This paper further develops the theory of constructing a fundamentally new class of system area networks––non-blocking dual photon networks with static self-routing. These networks have scalability, high speed inherent in photon systems, and complexity comparable to a full switch. The use of an extended scheme basis (dual photon switches and separate photon multiplexers and demultiplexers) allows balancing the scalability-speed and complexity-speed ratios. This paper proposes a method for constructing a two-stage fault-tolerant dual network with the indicated properties based on networks with the quasi-complete graph and quasi-complete digraph topologies and the invariant extension method with internal parallelization.
Keywords: photon switch, dual switch, photon multiplexers and demultiplexers, multi-stage switch, conflict-free self-routing, non-blocking switch, static self-routing, quasi-complete digraph, quasi-complete graph, switching properties, direct channels, scalability, speed and fault tolerance.
