| Abstract | ||
| The aim of this research is to design and simulate a fuzzy logic controller (FLC) to control the cell multiplexing in Asynchronous Transfer Mode(ATM) networking , which is a high performance cell oriented switching technology that utilizing of small size packet to carry different types of service for traffic and to show the effect of using the fuzzified variables (queuing message length 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, cell multiplexing, principles of fuzzy logic and internetworking with ATM network, the design process of system and the output of simulation. The cell flow rate on the output of fuzzy logic controller (FLC) which has been simulated depends on the input variables, one of them is the queuing message (message length), and the second one is the number of inputs. The simulation of fuzzy controller has been executed by using (MATLAB). In the light of this research, an important conclusion can be drawn, is that increasing of the fuzzified inputs variables means that cell queuing will increasing so the (FLC) will achieve size of packet to be large then the flow bit-rate of cell (control action) will decrease and when the number 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 ( message length and No. of inputs)as fuzzified variables in controlling cell multiplexing gives a flexible and a high speed responding to sudden changes in selective variables and get bit-rate which reduces time delay for different types of services(text, image, video and audio) which cause to get a high throughput, that is the maximum throughput under FLC parameters (with message length and No. of inputs) 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 | ||
