SIGNAL GENERATOR CIRCUIT AND PACKET TRANSFER APPARATUS

摘要

PROBLEM TO BE SOLVED: To quickly discard incoming packets at random with a variable possibility depending on the congesting condition by a small-scale circuit in a packet transfer apparatus.

SOLUTION: The signal generator circuit 100 for generating a signal at a predetermined possibility decides whether incoming packets are discarded, using a signal generator circuit having a means 101 for generating random numbers, a means 102 for holding a comparison constant for comparing with the random numbers, and a means 103 for generating a signal according to the comparison result of the random numbers with the constant.
