The Transmission Control Protocol (TCP) utilizes congestion avoidance and control mechanisms as a preventive measure against congestive collapse and as an adaptive measure in the presence of changing network conditions. The set of available congestion control algorithms is diverse, and while many have been studied from empirical and simulation perspectives, there is a notable lack of analytical...

Network traffic models have evolved significantly over the lifetime of the Internet. The earliest models were largely Poisson-based, designed for ease of analysis. The discovery of traffic self-similarity and long-range dependence required significant changes to traffic models. We examine this evolution from the early models, through the discovery of self-similarity, to the modern systems that ...

This paper presents a history of congestion control research and an analysis of a specific rate-based congestion control protocol, TCP-friendly rate control (TFRC). Two taxonomies of congestion control mechanisms are presented, and later used to classify general end-to-end congestion control schemes including window-based and rate-based methods. The classic TCP congestion control mechanisms are...

Problem statement: In most of the existing works either detection of congestion or scheme for congestion control in wireless sensor networks are presented. A very few works have been done, taken in to account of both congestion detection and congestion control. In most of the congestion detection works they have not achieved accuracy in detecting congestion and have resulted with high latency t...

We introduce a simple model of the Relentless Congestion Control proposed by Matt Mathis. Relentless Congestion Control (RCC) is a modification of the AIMD congestion control which consists in decreasing the TCP congestion window by the number of lost segments instead of halving it. Despite some ongoing discussions at the ICCRG IETF-group, this congestion control has, to the best of our knowled...

The demand for fast transfer of large volumes of data, and the deployment of the network infrastructures is ever increasing. However, the dominant transport protocol of today, TCP, does not meet this demand because it favors reliability over timeliness and fails to fully utilize the network capacity due to limitations of its conservative congestion control algorithm. The slow response of TCP in...

The performance of transport layer protocols can be affected differently due to wireless congestion, as opposed to network congestion. Using an active network evaluation strategy in a real world test-bed experiment, the Transport Control Protocol (TCP), Datagram Congestion Control Protocol (DCCP), and Stream Control Transport Protocol (SCTP) were evaluated to determine their effectiveness in te...

The concepts in congestion control for ATM networks are explained. The specifications for ATM traffic control proposed by ATM Forum are presented. Some representative schemes are described and compared.

Recent events have illustrated the Internet’s vulnerability to both denial of service (DoS) attacks and flash crowds in which links (or servers) in the network become severely congested. In both DoS attacks and flash crowds, the congestion is neither due to a single flow, nor due to a general increase in traffic, but to a well-defined subset of the traffic — an aggregate. This paper proposes ag...
