Active queue management (AQM) is a group of FIFO based queue management mechanisms in a router to support end-to-end congestion control in the Internet. Until random early detection (RED) was proposed by the internet engineering task force (IETF) for deploying[1], FIFO based tail drop (TD) was the only AQM mechanism used in the network. Two main functions are used in AQM: one is the congestion ...

SCTP is an emerging transport protocol that has TCP-like congestion control mechanism. This mechanism allows congestion to build up till packet loss occurs. The loss of packets leads to retransmissions causing excessive delay jitters and increasing traffic burden on the network. Moreover, the build-up of the congestion in the network causes the packets to suffer high queuing delays. We have emp...

In order to prevent congestion, the current internet uses endto-end congestion control protocol like TCP. In congestion control issues, queue management employed by router has been utmost important. Active queue management (AQM) has been proposed as a router-based mechanism for early detection of congestion inside the network. AQM scheme helps for end-to-end congestion control by having routers...

In the current Internet, TCP’s congestion control is performed end-to-end possibly assisted by simple and limited congestion feedback mechanisms in routers, e.g., Explicit Congestion Notification (ECN) or Random Early Detection (RED). In order to control network traffic load more accurately by reducing or even preventing congestion in (parts of) the network and improving the overall performance...

in trading electrical energy in deregulated power systems, violation of operation constraints such as transmission lines flow limits is possible. these conditions have been called “congestion”. one of the most important responsibility of independent system operator (iso) is congestion management in a manner that all the system equipments be operated in their nominal ranges. in this paper, usi...

With the development of high performance computing and increasing of network bandwidth, more and more applications require fast data transfer over high-speed long-distance networks. Research shows that the standard TCP Reno cannot fulfill the requirement of fast transfer of massive data due to its conservative congestion control mechanism. Some works have been proposed to improve the TCP throug...

With the rapid development of the Internet, the end-to-end TCP congestion control becomes insufficient in a multiple service circumstance. Many schemes have been proposed to solve the problem from different aspects. In this paper we propose a completely different approach, the node-to-node control, as a unified solution. It avoids congestion, prevents packet loss, and manages unresponsive traff...

With the continuous expanding of Internet scale, the network users and application increase rapidly and congestion control has become focus of network study. Several congestion control algorithms have been proposed out and improved for effective reduction of packet loss rate and for better utilization of network bandwidth. AQM (Active Queue Management) controls the queue length through intermed...

Applications of Wireless Sensor Networks (WSN) in harsh conditions usually cover a vast area with sensors randomly deployed by an uncontrolled method, e.g. dropped by helicopters. Thus the actual topology is unpredictable and can suffer from possible congestion. We propose the FCD framework for congestion detection, based on clustering techniques combined with Petri nets modelling and verificat...

We propose an end-to-end rate-based congestion avoidance scheme for ABR traac on ATM networks using explicit rate indication to sources. The scheme uses a new congestion detection technique and an O(1) switch algorithm to provide high thoughput, low queues, fair operation, quick convergence and a small set of well understood parameters.
