Abstract
The present invention reduces the delay time to extremely short by monitoring the output/distribution unit of the exchange node to specify the unused time slot as write destination of the data and performing priority control by the priority control signal contained in the data. The traffic congestion is resolved by performing write output to the specified time slot regardless of the communication speed of the transmission path of the data. Furthermore, the present invention aims to provide the exchange node and the exchange node control method that ensures communication quality by using the connection type as the communication method since the delay time in communication can be reduced.The exchange node 100 according to the present invention includes an input buffer unit 2, an identification unit 7, a distribution unit 5, a multiplexing circuit 9, a time slot allocation circuit 12, and an output/distribution unit 10. More preferably, a frame compression circuit 16, a frame decompression circuit 18 and a priority determination circuit 20 are arranged.
