The aim of this research is to design and simulate a fuzzy logiccontroller (FLC) to control the cell multiplexing in Asynchronous TransferMode(ATM) networking , which is a high performance cell oriented switchingtechnology that utilizing of small size packet to carry different types of service fortraffic and to show the effect of using the fuzzified variables (queuing messagelength and the number of inputs) on cell flow rate (control action) on the output of(FLC).The paper presents the previous works, principles of operations, cellmultiplexing, principles of fuzzy logic and internetworking with ATM network, thedesign process of system and the output of simulation. The cell flow rate on theoutput of fuzzy logic controller (FLC) which has been simulated depends on theinput variables, one of them is the queuing message (message length), and thesecond one is the number of inputs. The simulation of fuzzy controller has beenexecuted by using (MATLAB). In the light of this research, an importantconclusion can be drawn, is that increasing of the fuzzified inputs variables meansthat cell queuing will increasing so the (FLC) will achieve size of packet to belarge then the flow bit-rate of cell (control action) will decrease and when thenumber of inputs decreases that will let to achieve a high flow bit-rate as(M.Q=0.5,N=o.5,the control action (cell rate) =0.5 cells/s) and if (M.Q=0.2, N=0.5,the control action(cell rate=0.77 cells/s).Using parameters such as ( messagelength and No. of inputs)as fuzzified variables in controlling cell multiplexinggives a flexible and a high speed responding to sudden changes in selectivevariables and get bit-rate which reduces time delay for different types ofservices(text, image, video and audio) which cause to get a high throughput, that isthe maximum throughput under FLC parameters (with message length and No. ofinputs) is (562.7Mbit/s) for text message, (568Mbit/s) for image message,(563.4Mbit/s) for the video message and (563.4Mbit/s) for audio message
