In the current Internet, standard TCP congestion control is based on segment loss events possibly assisted by simple explicit router feedback mechanisms like Explicit Congestion Notification (ECN). The performance of TCP congestion control can be improved if a more sophisticated Router Congestion Feedback (RCF) mechanism than ECN is used. One of such approaches is Explicit Window Adaptation (EW...

Links with high bandwidth ranging from 1 to 10 Gbps are increasingly in use worldwide. Congestion control with the positive use of router feedback that explicitly indicates network conditions is a promising way to address the performance issues of congestion control especially in such high-speed networks. In this paper, we propose SIRENS, a scalable, robust, and flexible fine-grained explicit r...

The wireless technology is one of the core components of mobile applications with mobility support at low deployment costs. Among these, Wireless Mesh Network (WMN) is one of the technologies that supports mobile users for un-disrupted, reliable data connectivity, provides high bandwidth even in areas, where access of such services is difficult. Additionally, it features capabilities like self-...

Congestion avoidance mechanisms are used to prevent the saturation of the gateway which represents a bottleneck of the system. Recently, a new method for the congestion avoidance has been proposed: the smart access point with limited advertised window (SAP-LAW). The main idea is to hijack at the gateway the acknowledge packets in the transmission control protocol (TCP) connections in order to a...

This note describes a proposed addition of ECN (Explicit Congestion Notification) to IP. TCP is currently the dominant transport protocol used in the Internet. We begin by describing TCP’s use of packet drops as an indication of congestion. Next we argue that with the addition of active queue management (e.g., RED) to the Internet infrastructure, where routers detect congestion before the queue...

In a wireless network packet losses can be caused by not only nehvork congestion but also unreliaMe erropprone wireless links. Therebre, flow control schemes which use packet loss as a congestion measureemnot be directly applicable to a wireless network because there is no way to distinguish congestion losses from wireless losses In this paper, we extend so-called TCP-friendly flow control sche...

This paper describes the use of Congestion Pricing as a means of providing Congestion Control and Di erentiated Quality of Service. The application of the proposed technique to the Internet Protocol has the advantage that it can be simply implemented using Explicit Congestion Noti cation. In particular: the network mechanism is independent of higher level protocols; the end systems can continue...

The authors then attempt to patch together pieces from Ethernet and DCTCP into a sideband congestion control scheme (DCQCN). However, DCQCN remains an unsuccessful attempt to address the issues, as it continues to require the same blunt pause mechanisms that expose the network to congestion collapse. Thus, the paper serves as a proof that the RoCE idea of airlifting the “incompatible InfiniBand...

Bufferbloat is the existence of excessively large buffers in network devices, which can result in poor network performance. Techniques such as Automatic Queue Management and Explicit Congestion Notification are available to prevent the issue in Layer 3 queues, but are not widely deployed. In this paper we describe a method to successfully detect the effects of bufferbloat and the responsible li...

Fast Congestion Notification (FN) one of the proactive queue management mechanisms that practices congestion avoidance to help avoid the beginning of congestion by marking/dropping packets before the router’s queue gets full; and exercises congestion control, when congestion avoidance fails, by increasing the rate of packet marking/dropping. Upon arrival of each packet, FN uses the instantaneou...
