Abstract
In a cell rate supervising system for supervising a rate of cells flowing in a certain direction, a binary mode congestion feedback loop terminating unit terminates a first congestion feedback loop on a downstream side of that direction. The first congestion feedback loop receives a first congestion management cell from the downstream side and turns it in a binary mode to the downstream side. Also, an explicit rate (ER) mode congestion feedback loop terminating unit is provided on an upstream side of the binary mode congestion feedback loop terminating unit, and terminates a second congestion loop on an upstream side of the direction. The second congestion feedback loop receives a second congestion management cell from the upstream side and turns it in an ER mode to the upstream side. Further, a dynamic generic cell rate algorithm unit is provided on an upstream side of the ER mode congestion feedback loop terminating unit, and monitors the rate of cells in accordance with the second congestion management cell.
