<P>PROBLEM TO BE SOLVED: To effectively perform bandwidth control of a frame containing tag information in a communication device. <P>SOLUTION: A control device 13 generates threshold information 14a, which is associated with a port 11 to which a frame containing tag information is input, on the basis of relationship between ports 11a, 11b which output the frame containing the tag information, a destination address of the frame, and a bandwidth specified in the ports 11a, 11b. A reception processing module 14 measures a reception rate of the frame input from the port 11 according to the tag information and the destination address, and selects a frame which is preferentially discarded in the ports 11a, 11b on the basis of the reception rate and the threshold information 14a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
