Fuzzy RED: Congestion Control for TCP/IP Diff-Serv

Network congestion control remains a critical and high priority issue. The rapid growth of the Internet, the massive amount of data traffic it carries and increased demand to use the Internet for time-sensitive voice and video applications necessitates the design and utilization of effective congestion control algorithms. The reliance of the Internet on the TCP/IP protocol suite suggests that we must focus our efforts in this area. Existing TCP/IP protocol suite has been designed for best effort (delay tolerant) services and cannot effectively support time sensitive applications. Designing effective congestion control strategies to support such applications is known to be difficult because of the nature of services supported, and the variety of dynamic parameters involved. As a result, a number of researchers are now looking at alternative schemes that have the ability to cope with these difficulties in order to devise effective, robust congestion control techniques as an alternative (or supplement) to the traditional control approaches. One popular example of this approach is RE
