摘要:
An ATM switch network with an expansible optical ring, in which each switch forms several paths with a vertical ring, a horizontal ring and an expansible ring. The network has a large-capacity and a small switching interval, minimizing cell delay deviation and rendering the network suitable for high-speed multimedia service. A group switch node is formed by grouping the switches forming the vertical and horizontal rings, thereby enhancing reliability within a transmission interval by bisecting the wavelength division multiplexed logical paths and by using two optical lines. The network discriminates between I/O terminals for matching data having a low-speed small capacity and wavelength division I/O terminals for matching data having a high-speed large capacity. By using a node's I/O terminals, the network interconnects nodes via wavelength division multiplexing optical lines, thereby forming an automatic adaptive network. The network increases switching capacity, thereby improving communications in densely built-in areas.
