Predictive Fuzzy Logic Control of ABR Traffic in ATM Networks
نویسندگان
چکیده
In this paper, we propose an efficient and stable algorithm employing fuzzy logic for available bit rate (ABR) traffic. Large time-delay incurred in the feedback path and the statistical variation in the link capacity at the ATM node can cause instability or unfairness. The stability and fairness issues are discussed and the performance of the proposed mechanism is evaluated. key words: ABR, ATM, traÆc control, fuzzy logic control

The Design of a Fuzzy Logic Controller of an ATM Switch and its Simulation
Available Bit Rate (ABR) streams are carried whenever bandwidth is available to do so. When transporting MPEG streams over ATM networks, the link utilization cannot be brought close to 100% no matter how efficient the connection control admission scheme is, but can be improved by ABR traffic. Due to the unpredictable fluctuations and burstiness of the MPEG streams, it is difficult to accurately...
متن کاملA Fuzzy Logic Feedback Controller for ABR Traffic Management in ATM Networks
This paper presents a fuzzy logic feedback explicit-rate controller for the management of available bit rate (ABR) traffic in asynchronous transfer mode (ATM) networks. In our proposed flow control scheme, the switches will monitor the traffic on each link and feed periodic information to the fuzzy controller. The information is used by the controller to calculate an explicit cell rate to be se...
متن کاملIntelligent control techniques for efficient regulation of ABR queue length in ATM switches
Designing effective congestion control strategies for broadband networks is known to be difficult because of the variety of dynamic parameters involved such as link speeds, burstiness of the traffic, the distances between traffic sources and switching nodes. The uncertainties involved cause quantitative modeling of broadband networks almost impossible. Qualitative modeling techniques using the ...
متن کاملTraffic Control in Unicast ATM ABR Service using Adaptive Approach
This paper addresses the problem of rate control for Available Bit Rate (ABR) service class in Asynchronous Transfer Mode (ATM) networks. An adaptive neurofuzzy mechanism based on Adaptive Network Fuzzy Inference System (ANFIS) for allocating rates in ABR service has been proposed and compared with the fuzzy technique called as Fuzzy Explicit Rate Marking (FERM). To achieve this, a neurofuzzy A...
متن کاملFuzzy Backward Congestion Noti cation (FBCN) Congestion Control in Asynchronous Transfer Mode (ATM) Networks
In this paper, we study the performance of a fuzzy control scheme as a rst step to develop better control strategies for avoiding congestion and attaining high link utilisation in ATM based networks. Due to the complexity of ATM networks and many parameters involved, explicit modeling of their dynamic behaviour is very di cult if not impossible. On the other hand, for systems which are di cult ...
