Asynchronous transfer mode exchange system and priority control method |
摘要 |
A call reception control circuit 1 sets each guaranteed band width required for assuring communication quality of the respective band width demand classes in the corresponding N counter Nc, Ntv and Nv at a certain time interval Ts. The call reception control circuit 1 also sets values defined by the ratio of the W counter Wabr and Wubr of the respective best effort class to use the remained band width. The value 1 is subtracted from each value of the N counter Nc, Ntv and Nv and W counter Wabr and Wubr at every output of the cell from the corresponding class. A priority control process circuit 2 outputs cells to an output channel 3 according to priority levels giving a priority to the band width demand class having the value of the N counter not set to 0 over the band width demand class and the best effort classes having the value of the N counter set to 0.
