In this paper, a new active queue management (AQM) scheme that provides congestion control in TCP/IP networks using a fuzzy logic control approach is presented. The proposed scheme is implemented within the differentiated services (Diff-Serv) framework, providing quality of service (QoS). It is based on the fuzzy explicit marking (FEM) controller proposed to provide congestion control in TCP/IP best-effort networks. The proposed FEM In/Out (FIO) controller is evaluated in a wide range using the NS-2 simulator. The fuzzy control methodology can offer significant improvements on controlling congestion in TCP/IP Diff-Serv networks and providing adequate quality of service.
