A method for data flow control in a device using a layered communication protocol, in which method data units are transmitted asynchronously between two adjacent layers, and the data transmission rate is adjusted by controlling the transmission of data units. In order to provide a method with which if would be easy to allow for interlayer delays and buffering of primitives, the known "sliding window" method is applied in the method so that a serial number (x) is assigned to each data unit to be transmitted, and the transmitting layer maintains a transmission window (W) consisting of a variable group of serial numbers and transmits the data unit to be transmitted only if the serial number of that particular data unit is a part of said group. |
