Design and analysis for TCP-friendly window-based congestion control

چکیده
The current congestion control mechanisms for the Internet date back to the early 1980’s and were primarily designed to stop congestion collapse with the typical traffic of that era. In recent years the amount of traffic generated by real-time multimedia applications has substantially increased, and the existing congestion control often does not opt to those types of applications. By this reason, the Internet can be fall into a uncontrolled system such that the overall throughput oscillates too much by a single flow which in turn can lead a poor application performance. Apart from the network level concerns, those types of applications greatly care of end-to-end delay and smoother throughput in which the conventional congestion control schemes do not suit. In this research, we will investigate improving the state of congestion control for real-time and interactive multimedia applications. The focus of this work is to provide fairness among applications using different types of congestion control mechanisms to get a better link utilization, and to achieve smoother and predictable throughput with suitable end-to-end packet delay.

Designing TCP-Friendly Window-based Congestion Control for Real-time Multimedia Applications
Real-time multimedia applications prefer smooth and predictable throughput to TCP-like abrupt sending rate changes, and this led to the development of TCP-Friendly Rate-based Congestion Control (TFRC). However, we observed a longterm throughput imbalance between TFRC and TCP sources, especially under a low level of statistical multiplexing. We set out to reduce these differences by re-introduci...
متن کاملCongestion Control and an Analysis of TCP - friendly Rate Control
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...
متن کاملTCP-Friendly SIMD Congestion Control and Its Convergence Behavior
The increased diversity of Internet application requirements has spurred recent interests in exible congestion control mechanisms. Window-based congestion control schemes use increase rules to probe available bandwidth, and decrease rules to back o when congestion is detected. The parameterization of these control rules is done so as to ensure that the resulting protocol is TCP-friendly in term...
متن کاملAnalysis on Adjustment-Based TCP-Friendly Congestion Control: Fairness and Stability
In this paper, we focus on understanding the binomial congestion control algorithms, which is proposed in [11] and can generalize TCP-style additive-increase by increasing inversely proportional to a power k of the current window (for TCP, k=0) and generalize TCP-style multiplicative-decrease by decreasing proportional to a power l of the current window (for TCP, l=1). We discuss their global f...
متن کاملA Theory of Window-based Unicast Congestion Control
This work presents a comprehensive theoretical framework for window-based congestion control protocols that are designed to converge to fairness and efficiency. We first derive a sufficient condition for convergence to fairness. Using this, we show how fair window increase/decrease policies can be constructed from suitable pairs of monotonically non-decreasing functions. We show that well-studi...
