Abstract :
Studies were carried out on an ATM (asynchronous transfer mode) transport network based on the virtual path concept. An arrangement of node functions in this network is proposed in which the call set-up process is excluded from transit nodes. This leads to a reduction in node processing and simplification of equipment by specialization of transit node functions. Virtual path control is shown to bring benefits in efficiency and flexibility. Among them a transmission efficiency improvement due to bandwidth control, a simple three-value bandwidth control algorithm improves the efficiency considerably with only a slight processing increase. It is concluded that the virtual path concept can provide simple, economical, flexible, and high-performance networks
