The hardware and the communimtion protocol of a statable optical ring have been designed. A hoxdware routing has been achieved on the network interface card to minimize data paeket communieation latency and a simplified communication protocol has been designed to reduce communication overheads. To reduce the data packet bilking probability and have a more efficient umgn of the data link layer bandwidth, a virtuaI multi channel transmimion mechanism has been achieved. The network supports a maximum of 16 virtual channds for each physical data link, Time slots can be dynamically assigned to each virtual channel. Zero wait time has been achieved for the switching between different virtual channels.
