Abstract. In this paper, a new active queue management (AQM) algorithm for data traffic control in TCP/IP networks is developed. The algorithm design is based on the principles of discrete sliding-mode control. Unlike majority of earlier studies, the design procedure considers the effects of both non-negligible delay in transferring data and feedback information and unpredictable capacity varia...

Denial of Service (DoS) attacks are currently one of the biggest risks any organization connected to the Internet can face. Hence, the congestion handling techniques at the edge router(s), such as Active Queue Management (AQM) schemes must take into account such attacks. Ideally, an AQM scheme should (a) ensure that each network flow gets its fair share of bandwidth, and (b) identify attack flo...

The virtual rate control (VRC) algorithm has been proposed for active queue management (AQM) in TCP networks. This algorithm uses an adaptive rate control instead of queue length control in order to respond quickly to traffic change with high utilization and small loss. By introducing the notion of virtual target rate, the VRC algorithm can maintain an input rate around the target rate, while a...

The Routers in Internet face the problem of congestion due to the increased use of Internet. Active Queue Management has provided a solution to the problem of congestion control in the Internet routers. But as data traffic is bursty in routers, burstiness must be handled without comprising the high link utilization and low queuing delay. Congested link leads to many problems such as large delay...

The congestion on the internet is main issue that affects performance of transition data over network. An algorithm for control required to keep any network efficient and reliable transfer traffic users. Many Algorithms had been suggested years improve occurs in such as drop tail packets. Recently there are many algorithms have developed overcome drawback procedure. One important active queue m...

Internet represents a shared resource wherein users contend for the finite network bandwidth. Contention among independent user demands can result in congestion, which in turn leads to long queuing delays, packet losses or both. Congestion control regulates the rate at which traffic sources inject packets into a network to ensure high bandwidth utilization while avoiding network congestion. Thi...

Abstract—A Particle Swarm optimized Fuzzy Logic Congestion Detection (FLCD) was recently proposed for best-effort service networks. This algorithm synergically combines the good characteristics of traditional Active Queue Management (AQM) algorithms and fuzzy logic based AQM algorithms. Its membership functions are designed automatically by using a Multi-objective Particle Swarm Optimization (M...

—This paper presents and analyses the implementation of a novel active queue management (AQM) named FavourQueue that aims to improve delay transfer of short lived TCP flows over a best-effort network. The idea is to dequeue in first packets that do not belong to a flow previously enqueued. The rationale is to mitigate the delay induced by long-lived TCP flows over the pace of short TCP data req...

The traffic characteristics of real-time and non real-time applications require a certain Quality of Service (QoS) from the Internet in terms of bandwidth, delay, packet loss, fairness and jitter. However, most of the current Active Queue Management (AQM) algorithms at the internet routers do not guarantee QoS for real time traffics such as video and audio. This is because; most of the algorith...
