Fuzzy based dual active queue management scheme for high performance networks

In recent years, active queue management schemes (AQM) with explicit congestion notification (ECN), which support the end-to-end congestion control mechanism of TCP/IP by performing congestion control, have been actively studied by many researchers. It is used to improve the performance of TCP/IP networks. Fuzzy double slope random early detection (FDSRED) and fuzzy enhanced random exponential marking (FEREM) are an efficient active queue management schemes to achieve high link utilization with low queuing delay. However, in our study, we reveal that, FDSRED has better throughput and low delay for low load of networks and FEREM has better throughput and low delay for heavy load of networks. In this paper, we have combined both FDSRED and FEREM with fuzzy aggregation operations called dual AQM. Result shows that our proposed scheme "fuzzy based dual active queue management scheme for high performance networks" achieves better throughput and low delay for both low load and heavy load of networks.
