Circuit networks, especially optical circuit networks, are characterized by high bandwidths and latencies. This thesis shows how circuit caching can improve connection latencies for some traffic patterns particularly ones that exhibit locality in either the source or destination node sets.

A circuit is cached by allowing all, or part, of an established circuit to persist, to be potentially reused, after a typical circuit-switched network would have torn it down. A static function giving the lowest latency path for a message does not exist because switches are not assumed to be reset after every message, so message paths must be dynamically calculated. A packet network is run in parallel with the circuit-cached network to further improve latencies and caching performance. Simulations are used to study the topology, caching, and traffic patterns in these circuit-cached hybrid networks.
