Abstract
A method related to a data communication system, and more specifically to frame relay multiplexing, in which system data frames are forwarded by nodes performing inter alia multiplexing and concentration of traffic from a plurality of input sources, and wherein the sum of transmission time in question, the queue delay and acknowledge frame transmission time, should not exceed a transmission timer setting, and for the purpose of solving the problem with queuing of data frames in such a communication network, it is according to the present invention suggested to combine the following steps: a) simulating an output queue length, b) estimating an input source traffic value, and c) using fuzzy logic, for thereby deciding when a data frame has to be deleted from the data stream.
