IPC: H04L12/931
Filed: 2000-04-11
Abstract: PROBLEM TO BE SOLVED: To provide a packet switch and a packet switching method that uses the scheduler of a small scale can ensure the quality of service QoS. SOLUTION: Input buffer sections 1-1 to 1-N correspond to input channels 1-N, form a block sequentially from packets with high priority addressed to a same output path and transmit assembled data. A scheduler section 6 applies contention arbitration to the transmitted data, and an N×N switch section 4 switches the connection of the data to output channels 1-N, on the basis of the contention arbitration. Thus, a scheduler by the QoS class is not required, while warranting the QoS, the scale of the scheduler is reduced, and a configuration which does not notify the class is attained for the scheduler. Furthermore, a long processing time is taken for the input buffers and the scheduler, the processing for the input buffers and the scheduler is facilitated and a high throughput is obtained for the traffic.
