Designing TCP-Friendly Window-based Congestion Control for Real-time Multimedia Applications
نویسندگان
چکیده
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-introducing a TCPlike Ack mechanism while retaining the TCP throughput equation to compute the congestion window. The outcome, TCP-Friendly Window-based Congestion Control (TFWC), is fairer than TFRC when competing with TCP, and is simpler to implement in real-world applications.

Design and analysis for TCP-friendly window-based congestion control
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 reaso...
متن کاملAnalysis of TCP-friendly Congestion Control Algorithms
TCP is the dominant transport protocol in the Internet. However, the increase-by-one decrease-to-half strategy used by TCP is not suitable for many multimedia applications. Many TCP-friendly congestion control algorithms have been proposed as an alternative to the TCP to suit the needs of multimedia applications. In this paper, we analyze the short-term behavior of three TCP-friendly congestion...
متن کاملTCP-friendly congestion control for streaming real-time applications over wireless networks
Congestion control for streaming real-time applications, which need smoothness of the transmission rate, should be transmission control protocol (TCP)-friendly. Moreover, in wireless networks, TCP-friendly congestion control should be based on differentiation of packet losses due to congestion and wireless link error to improve network utilisation. The authors propose a TCP-friendly congestion ...
متن کاملDynamic Quality Adaptation Mechanisms for TCP-friendly MPEG Video Transfer
With the proliferation of real-time multimedia applications, bandwidth available to TCP connections is oppressed by “greedy” UDP traffic and the performance of TCP connections extremely deteriorates. In order that both TCP and UDP sessions fairly co-exist in the Internet, UDP sessions should react properly against congestion as TCP does. In this thesis, we first build an MPEG-2 video transmissi...
متن کاملTCP-friendly Congestion Control for Real-time Streaming Applications
This paper introduces and analyzes a class of nonlinear congestion control algorithms called binomial algorithms, motivated in part by the needs of streaming audio and video applications for which a drastic reduction in transmission rate upon congestion is problematic. Binomial algorithms generalize TCP-style additive-increase by increasing inversely proportional to a power k of the current win...
