Title: Priority controller and its method
Inventor: USUKURA TAKASHI
IPC: H04L47/6275
Filed: 2000-10-20
Abstract: PROBLEM TO BE SOLVED: To obtain a priority controller which does not affect the priority of a data matrix group which is out of compensation. SOLUTION: When an output signal obtained by multiplexing (k), (m) and (n) input matrices (k, m and n are positive integers) inputted to respective multiplexers (1 to 3) is transmitted to input routes (4 to 6) as data matrices, the output signal of the data matrices is selected, weighted by a weighted round Robin(WRR) control unit (10), and outputted as a single output matrix. Consequently, the average of total bands of data matrices is less than the bands of a data matrix group transmitted to an output route (7). When a specific input data matrix out of input data matrices inputted to a certain input data matrix group is inputted in a state exceeding a weighting state, the weighting of input data matrices which keep the other weightings existing in the same data matrix group is prevented from being reduced relatively.
