RED for Improving TCP Over Wireless Networks

White Paper Explicit Congestion Notification (ECN) is known as an effective mechanism that can be used with Active Queue Management (e.g. TCP was designed and tuned to work well on networks where losses are mainly congestion losses. [03 Jul 2008]

Influence of False Congestion Alarms on Performance for Congestion Control Based on Dynamic Window Flow Mechanism in Wireless Networks

White Paper The congestion detection mechanism of congestion control based on dynamic window flow control, which is widely used for reliable window protocols such as TCP, is well-known to be simple, but it may raise false alarms: a sender usually interprets... [03 Jul 2008]

Adaptive Video Streaming in Presence of Wireless Errors

White Paper Real-time video streaming with rate adaptation to network load/congestion represents an efficient solution to its coexistence with conventional TCP data services. This paper introduces the Video Transport Protocol (VTP) with a new rate control... [03 Jul 2008]

A Mean-Field Model for Multiple TCP Connections Through a Buffer Implementing RED

White Paper Here the paper models multiple connections maintained in the congestion avoidance regime by the RED mechanism. The idea is to detect congestion before the buffer overflows and packets are lost. Active queue management schemes like RED (Random Early... [03 Jul 2008]

Impact of Network Delay Variations on Multicast Sessions With TCP-Like Congestion Control

White Paper This paper studies the impact of randomness (i.e.queueing delay) on the performance of a (one-to-many) multicast session in the presence of a "TCP-like" congestion control mechanism. TCP-friendly congestion control has been advocated by the IRTF... [03 Jul 2008]

UDT: An Application Level Transport Protocol for Grid Computing

White Paper UDT has a congestion control mechanism that maintains efficiency, fairness and stability, and its application-level nature enables it to be deployed at the lowest cost, without any changes in the network infrastructure or operating systems. [10 Apr 2008]

Impact of TCP-Like Congestion Control on the Throughput of Multicast Groups

White Paper This paper studies the impact of randomness (i.e.variation of queuing delay due to cross traffic) on the performance of a (one-to-many) multicast session in the presence of a "TCP-like" congestion control mechanism. [04 Apr 2008]

Handling Two-Way TCP Traffic in Asymmetric Networks

White Paper The TCP congestion control protocol is mainly designed for bandwidth symmetric paths. As two-way asymmetric connections will probably become common case in the future with the widespread use of ADSL, satellites and other high-speed technologies, it... [15 Jan 2008]

Equation-Based Approach to TCP-Compatible Multicast Congestion Control for Layered Transmission in Low-Multiplexing Environments

White Paper In this paper, the applicability of an equation-based mechanism to congestion control for a protocol which bases its join and leave actions on the calculation of the TCP response function is investigated. [15 Jan 2008]

A HighSpeed TCP Study: Characteristics and Deployment Issues

White Paper The current congestion control mechanism used in TCP has difficulty reaching full utilization on high speed links, particularly on wide-area connections. HighSpeed TCP was recently proposed as a modification of TCP's congestion control mechanism to... [15 Jan 2008]

On Fair Window Control for TCP With ECN Using Congestion Level

White Paper The current congestion control mechanism for TCP with ECN suffers from the oscillation of the window size and the unfair sharing of network resources. These problems are caused by the insufficient information about the congestion level of a network... [15 Jan 2008]

Survey on Fairness Issues in TCP Congestion Control Mechanisms

White Paper Those are modifications of TCP congestion control mechanism and router support for achieving the fair service among TCP connections. This paper surveys the fairness issues in the congestion control mechanisms of TCP, which is one of most important... [15 Jan 2008]

Steady State Analysis of TCP Connections With Different Propagation Delays

White Paper The approach was to separately model the TCP congestion control mechanism and the network using the fluid flow approximation and the queuing theory, respectively. This paper has modeled the congestion control mechanism of TCP as a SISO (Single... [15 Jan 2008]

A New Congestion Control Mechanism of TCP With Inline Network Measurement

White Paper This paper proposes a novel congestion control mechanism of TCP, by using an inline network measurement technique. By using information of available bandwidth of a network path between sender and receiver hosts, it constructs quite a different... [15 Jan 2008]

TCP Rate Control Using Active ECN Mechanism With RTT-Based Marking Probability

White Paper The end-to-end TCP congestion control based on a window flow control mechanism can cause unfairness among multiple TCP connections with different RTT (Round Trip Time), due to its non-uniform increase of the rate. [15 Jan 2008]
