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 b...

TCP trunking is a novel way of applying TCP congestion control to bandwidth management of aggregate traffic. This is accomplished by setting up a separate TCP connection to probe network congestion, and then using the TCP connection’s congestion control to regulate the bandwidth usage of the aggregate traffic. TCP trunking offers several advantages in managing bandwidth of aggregate traffic. It...

The main reason for network congestion is using TCP/IP protocol for transmission. In this paper, the technique called bandwidth estimation is used to avoid congestion in the network which uses TCP/IP protocol mechanism. It finds out the equilibrium point of the window and then the size of the window is adjusted in a round trip time. Initially the TCP and Active Queue Management technique is dis...

Three problems in TCP performance analysis and congestion management

This paper addresses the problem of congestion control for transmission control protocol (TCP) traffic in the Internet. The method proposed builds on the ideas of TCP Vegas, a true feedback control approach to congestion management of TCP traffic. The new method is based on an adaptive linear quadratic Gaussian (LQG) formulation which uses an extended least squares system identification algorit...

The application of backward explicit congestion noti cation (BECN) to an ATM LAN is investigated in order to support the dynamic sharing of bandwidth between high-speed, bursty, data tra c sources. The results of a simulation study are presented which suggest that a BECN mechanism may provide simple and e ective tra c management for an ATM LAN or campus backbone network of up to at least 50 km ...

Congestion in on-chip networks may cause many drawbacks in multiprocessor systems including throughput reduction, increase in latency, and additional power consumption. Furthermore, conventional congestion control methods, employed for on-chip networks, cannot efficiently collect congestion information and distribute them over the on-chip network. In this paper, we present an on-chip network ar...

In this paper, a scheme based on generators and loads real and reactive power flow contribution factors has been presented for congestion management in pool based electricity markets. The system operator (SO) can identify the generators and loads based on these contribution factors for rescheduling their real and reactive power generation and loads to manage congestion. The real and reactive po...

Quick and reliable estimation of traffic conditions is of critical importance for advanced traffic management systems, especially when heavy congestion occurs. This paper proposes a methodology to predict queue spillovers in city street networks with signalized intersections using data from loop detectors (counts and occupancy). The key idea of the developed methodology is that when spillovers ...

Traffic congestion can be evaluated in various ways that result in very different conclusions about the nature of the problem and optimal solutions. This paper describes various factors that affect congestion costing and the evaluation of potential congestion reduction strategies, including the scope of analysis, baseline speeds, travel time unit costs, the impacts of traffic speeds on accident...
