<p>PROBLEM TO BE SOLVED: To avoid congestion by providing a threshold for discriminating the precursor of packet congestion stepwise below a threshold for detecting overflow. SOLUTION: A system for avoiding packet transfer congestion is provided with a packet inflow monitor part 1 which monitors inflow of packets with respect to packet transfer for loading and taking out flowing-in packets in and from a buffer and transferring them, a packet switch 2 which distributes flowing-in packets from the packet inflow monitor part 1 to a non-stagnating output buffer 3-2 by a packet stagnation report signal, and an output buffer 3-1 which loads and takes out flowing-in packets from the packet switch 2 and discriminates the degree of stagnation of flowing-in packets in the buffer by a stagnation discrimination value lower than the threshold for detecting overflow of the buffer and sends discrimination information to the packet switch 2 as the packet stagnation report signal.</p> |
