TLDR
It is argued that router mechanisms are needed to identify and restrict the bandwidth of selected high-bandwidth best-effort flows in times of congestion, and several general approaches are discussed for identifying those flows suitable for bandwidth regulation.Abstract:
This paper considers the potentially negative impacts of an increasing deployment of non-congestion-controlled best-effort traffic on the Internet. These negative impacts range from extreme unfairness against competing TCP traffic to the potential for congestion collapse. To promote the inclusion of end-to-end congestion control in the design of future protocols using best-effort traffic, we argue that router mechanisms are needed to identify and restrict the bandwidth of selected high-bandwidth best-effort flows in times of congestion. The paper discusses several general approaches for identifying those flows suitable for bandwidth regulation. These approaches are to identify a high-bandwidth flow in times of congestion as unresponsive, "not TCP-friendly", or simply using disproportionate bandwidth. A flow that is not "TCP-friendly" is one whose long-term arrival rate exceeds that of any conformant TCP in the same circumstances. An unresponsive flow is one failing to reduce its offered load at a router in response to an increased packet drop rate, and a disproportionate-bandwidth flow is one that uses considerably more bandwidth than other flows in a time of congestion.read more

TCP Congestion Control
TL;DR: This document defines TCP's four intertwined congestion control algorithms: slow start, congestion avoidance, fast retransmit, and fast recovery, as well as discussing various acknowledgment generation methods.

Equation-based congestion control for unicast applications
TL;DR: A mechanism for equation-based congestion control for unicast traffic that refrains from reducing the sending rate in half in response to a single packet drop, and uses both simulations and experiments over the Internet to explore performance.
HighSpeed TCP for Large Congestion Windows
TL;DR: The proposals in this document are experimental and while they may be deployed in the current Internet, they do not represent a consensus that this is the best method for high-speed congestion control.

A transmission control scheme for media access in sensor networks
Alec Woo,David E. Culler +1 more
TL;DR: This work proposes an adaptive rate control mechanism aiming to support media access control in sensor networks and finds that such a scheme is most effective in achieving the authors' fairness goal while being energy efficient for both low and high duty cycle of network traffic.
Journal ArticleDOI
Controlling high bandwidth aggregates in the network
TL;DR: The design involves both a local mechanism for detecting and controlling an aggregate at a single router, and a cooperative pushback mechanism in which a router can ask upstream routers to control an aggregate.

The Evolution of Cooperation
TL;DR: In this paper, a model based on the concept of an evolutionarily stable strategy in the context of the Prisoner's Dilemma game was developed for cooperation in organisms, and the results of a computer tournament showed how cooperation based on reciprocity can get started in an asocial world, can thrive while interacting with a wide range of other strategies, and can resist invasion once fully established.

Random early detection gateways for congestion avoidance
Sally Floyd,Van Jacobson +1 more
TL;DR: Red gateways are designed to accompany a transport-layer congestion control protocol such as TCP and have no bias against bursty traffic and avoids the global synchronization of many connections decreasing their window at the same time.

Congestion avoidance and control
TL;DR: The measurements and the reports of beta testers suggest that the final product is fairly good at dealing with congested conditions on the Internet, and an algorithm recently developed by Phil Karn of Bell Communications Research is described in a soon-to-be-published RFC.
Security Architecture for the Internet Protocol
TL;DR: This document describes an updated version of the "Security Architecture for IP", which is designed to provide security services for traffic at the IP layer, and obsoletes RFC 2401 (November 1998).
