Instead of the increase-by-one decrease-to-half strategy used in TCP for congestion window adjustment, we consider the general case such that the increase value and decrease ratio are parameters. That is, in the congestion avoidance state, the window size is increased by per window of packets acknowledged and it is decreased to of the current value when there is congestion indication. We refer ...

The growth of network intensive Internet applications has made gateway congestion control a high priority. The IETF Performance and Congestion Control Working Group surveyed and reviewed gateway congestion control and avoidance approaches in a series of meetings during 1988 and 1989. The purpose of this paper is to present our review of the congestion control approaches, as a way of encouraging...

A new, easily traceable congestion control scheme which only requires bandwidth information from rare packets that query routers is presented. In contrast with TCP, the (very simple) rate calculation can be performed by any node that sees the occasional feedback message from the receiver; this facilitates load based charging as well as enforcing appropriate behaviour. The control law, which is ...

We introduce a receiver-oriented approach to congestion control, demonstrated by an experimental protocol, TCP-Real. The protocol allows for a measurement-based transmission strategy, which complements the "blind" increase/decrease window adjustments. Owing to its design, the protocol displays an inherent property to produce comprehensive dynamics in heterogeneous environments with wired or wir...

Several congestion pricing proposals have been made in the last decade. Usually, however, those proposals studied optimal strategies and did not focus on implementation issues. Our main contribution in this paper is to address implementation issues for congestion-sensitive pricing over a single domain of the differentiated-services (diff-serv) architecture of the Internet. We propose a new cong...

In the TCP network environment system the researcher and developer mainly focus on congestion control. The existing paper provides an analysis of congestion metric with or without flow of information in queue based AQM algorithms, on the basis of the algorithms, proposed a new algorithm APAQM (An Alternative path Active Queue Management Congestion control Algorithm). An Alternative path Active ...

Congestion has been considered as one of the basic important issue in packet switched network [1][9]. Congestion control refers to the mechanisms and techniques to control the congestion and keep the load below the capacity. This paper provides an overview of category provided by congestion control .It also includes how TCP uses congestion control to avoid congestion or alleviate congestion in ...

In this paper an effort has been made to study various Congestion control techniques used for reducing/easing the level of congestion and subsequently avoiding the congestion of the wired communication networks in general and High Speed Networks in particular. Many authors have suggested several congestion control techniques [2], [3], [4], [8], [12], [14], [15], [23], [29], [32] & [33] and stud...

The TCP Incast congestion happens in data center network, when multiple data senders simultaneously communicate with a single receiver namely in many-toone pattern. The regular TCP does not perform well in high-speed and low-latency network. To mitigate this problem,we propose a novel enhanced TCP protocol called IMTCP (Incast Mitigation TCP ). IMTCP leverages ECN with two-bits to provide expli...

Adaptive Model Predictive Transmission Control Protocol (AMP-TCP) as a new TCP delay-based congestion control algorithm is introduced. Both aspects of design and implementation of the algorithm are described using simulations on the ns-2 network simulator. The design stage is composed of two steps. First, a recursive system identification approach is proposed to capture the network delay dynami...
