This paper introduces a proto-type model of a superconducting packet switch which is composed of an input buffer, a contention solver, and a distribution network. The contention solver checks for contention by comparing packet addresses while sorting the packets. The input buffer is used for waiting when contention occurs. The distribution network distributes packets which are guaranteed to be contention-free by the contention solver. The design of the proto-type has been completed and the operation has been numerically simulated and confirmed. The elementary circuits of the input buffer, the contention solver, and the distribution network are fabricated by standard Nb tri-layer process and the correct operations are confirmed.
