ABSTRACT:
A cell transmission rate control scheme in ATM network, capable of preventing incorrect updating of information in a resource management (RM) cell. The RM cell having an explicit cell rate field is transmitted and returned between the first and second end-nodes. A first cell transmission rate value written in the explicit cell rate field of the RM cell transmitted by the first end-node is stored at a control unit provided on the ATM network, and a second cell transmission rate value written in the explicit cell rate field of the RM cell returned by the second end-node is detected at the control unit. When the second cell transmission rate value is larger than the first cell transmission rate value, the second cell transmission rate value is rewritten into the first cell transmission rate value in the explicit cell rate field of the RM cell returned by the second end-node at the control unit.
