Congestion control using fuzzy logic in differentiated services networks

The basic objectives of future Internet are to increase the network capacity, to offer practically differentiated services for traffic with different requirements such as real-time and non-real-time services. These objectives introduce very strict requirements for traffic control systems and lead to the establishment of Differentiated Services (DS) concept. However, the new features of DS networks, where several classes of precedence are allowed, lead the inefficiency of the congestion control approaches for the existed best-effort Internet. In this paper, a new congestion control approach using fuzzy logic in the DS domain is presented. Simulation shows that the approach is efficient and promising.
