On Hybrid TCP Congestion Control

چکیده
This paper presents several considerations on the hybrid TCP congestion control, in which lossbased schemes like TCP-Reno and delay-based schemes like TCP-Vegas are combined in a smart way. We firstly introduce simple analytical models of loss-based TCP, delay-based TCP and their hybrid. With support of experimental results, effectiveness of the hybrid TCP is proved. Then, we try to develop a more detailed model of TCP-Fusion, which we had proposed and is one of hybrid TCPs. We furthermore present delay-based TCP friendly rate control as a by-product of the analytical modeling, which has a potential to surpass the classical TFRC.

A Hybrid Systems Framework for TCP Congestion Control: A Theoretical Model and its Simulation-based Validation
In this paper we make use of hybrid systems to model the transient and steady-state behavior of multiple TCP flows that share a single common bottleneck link. The contributions of our models include: (1) a more complete description of TCP’s behavior, including the effect of queuing, interaction among competing flows, and finite advertised window size, (2) theoretical prediction of phenomena suc...
متن کاملEvaluation of Congestion Control Mechanism for Video Streaming
In recent years, video streaming services over TCP, such as YouTube, have become more and more popular. TCP NewReno, the current TCP standard, performs greedy congestion control, which increases the congestion window size until packet loss occurs. Therefore, because TCP transmits data at a much higher rate than the video playback rate, the probability of packet loss in the network increases, wh...
متن کاملModeling the Transient Rate Behavior of Bandwidth Sharing as a Hybrid Control System
This paper uses hybrid control to model a problem of computer network systems, the dynamic behavior of bandwidth sharing among competing TCP traffic. It has been well known in the computer network community that well-behaved (TCP-friendly) congestion control mechanisms are crucial to the robustness of the Internet. Congestion control determines the transmission rate for each flow. Right now, mo...

TCP congestion control was designed and optimized for wired networks. During recent years, however, the popularity of wireless network infrastructures enabling ubiquitous Internet access, such as Universal Mobile Telecommunication System (UMTS), has grown considerably. As a consequence, many improved TCP congestion control algorithms, able to effectively operate over hybrid wired/wireless netwo...
متن کاملHybrid Modeling of TCP Congestion Control
In this paper we propose a hybrid model for TCP’s congestion control mechanism operating under drop-tail queuing policy. Using this model we confirmed the standard formula T := 1.23 RTT √ p used by TCP-friendly congestion control algorithms, which relates the average packet drop rate p, the average round-trip time RTT , and the average throughput T . The hybrid model also allows us to understan...
