Traffic Management using Multilevel Explicit Congestion Notification
نویسندگان
چکیده
In this paper we present a new traffic management scheme based on an enhanced Explicit Congestion Notification (ECN) mechanism. In particular we used multilevel ECN, which conveys more accurate feedback information about the network congestion status than the current two levels ECN. We have designed a TCP source reaction that takes advantage of the extra information about congestion and tunes better its response to the congestion than the current schemes. Our analysis and simulations results shows that our scheme performed better than the current ones, having less losses, better network utilization, better fairness, and the solution is scalable.

Congestion Control Using Multilevel Explicit Congestion Notification
Congestion remains one of the main obstacles to the Quality of Service (QoS) on the Internet. We think that a good solution to Internet congestion should optimally combine congestion signaling from network and source reaction, with the following as its main goals: minimum losses and delays, maximum network utilization, fairness among flows, and last but not least, scalability of the solution. T...

متن کاملFuzzy Logic Control for Active Queue Management in TCP/IP Networks
This paper presents a new active queue management (AQM) scheme, Fuzzy Explicit Marking (FEM), supporting explicit congestion notification (ECN), to provide congestion control in TCP/IP best-effort networks using a fuzzy logic control approach. While many AQM mechanisms have recently been proposed, these require careful configuration of non-intuitive control parameters, and show weaknesses to de...

متن کاملAnalysis of RED-Family Active Queue Management Over a Wide-Range of TCP Loads
RED is an Active Queue Management (AQM) technique that is intended to achieve high link utilization with a low queuing delay. Recent studies show that RED is difficult to configure for some rapidly changing traffic mixes and loads [2]. Other studies show that under some conditions, the performance gains of RED and its variants over traditional drop-tail queue management is not significant given...
