Modeling and Analysis of a Hybrid Computer Network.

A hybrid computer network which dynamically changes switching techniques from packet switching to circuit switching depending upon path length, message length, traffic intensity, and number of channels is modeled and compared to the conventional switching techniques of circuit and packet switching. Initially, the circuit switching and packet switching models are constructed using Q-Gert and compared to determine which switching technique provides the smallest delays as the factors of message length, path length, traffic intensity, and number of channels are varied. The operation of hybrid switching network is defined and the network modeled using the results from comparing the circuit and packet switched models to determine when the hybrid network will be operating in the circuit switched or packet switched mode. The three models are compared to determine if the hybrid network as defined is feasible. The comparison clearly demonstrates the hybrid network consistently produces delays equal to the delays from circuit switching when it is the best and from packet switching when it is the best. Author
