RSS congestionTCP Westwood: Congestion Window Control Using Bandwidth Estimation
White Paper This paper studies the performance of TCP Westwood (TCPW), a new TCP protocol with a sender-side modification of the window congestion control scheme. The estimated connection rate is then used to compute congestion window and slow start threshold... [04 Dec 2007]
TCP-Fusion: A Hybrid Congestion Control Algorithm for High-Speed Networks
White Paper This paper presents a new congestion control algorithm of TCP, called TCP-Fusion, and provides its extensive evaluation results through simulations and implementations. Recently, towards high-speed networks with large bandwidth delay product, a... [30 Oct 2007]
TCP-DCR: Making TCP Robust to Non-Congestion Events
White Paper The strength of TCP lies in the fact that it tries to mitigate congestion in the network by reducing the sending rate in response to loss of packets. Historically, using packet loss as a measure for perceiving congestion has worked quite well. [14 Jan 2008]
TCP-Friendly SIMD Congestion Control and Its Convergence Behavior
White Paper The increased diversity of Internet application requirements has spurred recent interests in flexible congestion control mechanisms. Window-based congestion control schemes use increase rules to probe available bandwidth, and decrease rules to back... [06 Nov 2007]
TCP-Illinois: A Loss and Delay-Based Congestion Control Algorithm for High-Speed Networks
White Paper This paper introduces a new congestion control algorithm for high speed networks, called TCP-Illinois. TCP-Illinois uses packet loss information to determine whether the window size should be increased or decreased, and uses queueing delay... [06 Nov 2007]
Enhancing TCP Congestion Control Via Connection Bandwidth Estimation, A Performance Study
This paper presents performance studies of TCP Westwood (TCPW), a sender-side modification of the congestion window control scheme in TCP. The estimate is then used to compute congestion window and slow start threshold after a congestion episode... [05 Dec 2007]
IT and the Congestion Charge: So far, so good
Comment If you read certain national newspapers (and London's Evening Standard), you could be forgiven for thinking our capital city was going to experience meltdown this morning as traffic chaos struck the streets circling the Congestion Charge Zone and... [17 Feb 2003]
TCP-Friendly Rate Control With Token Bucket for VoIP Congestion Control
White Paper TCP Friendly Rate Control (TFRC) is a congestion control algorithm that provides a smooth transmission rate for real-time network applications. A problem with TFRC is that it uses additive increase to adjust the sending rate during periods with no... [06 Nov 2007]
Intelligent Transportation Solutions Help Speed Traffic, Ease Congestion and Generate Revenue for State and Local Governments
White Paper State and local governments need traffic management solutions that can be implemented quickly and cost-effectively to help ease congestion on existing roads, encourage use of public transit and generate new revenues to fund infrastructure... [03 Jul 2008]
Generalized Window Advertising for TCP Congestion Control
Congestion in the Internet is a major cause of network performance degradation. The Generalized Window Advertising (GWA) scheme proposed in this paper is a new approach for enhancing the congestion control properties of TCP. [06 Dec 2007]
Modified TCP Congestion Control Algorithm for Throughput Enhancement in Wired-Cum-Wireless Networks
White Paper The key idea proposed in this paper is to determine the Optimal Congestion Window for a TCP Sender in a particular network scenario (that corresponds to the fair share of that connection) and keep this congestion window a constant to a point where... [06 Nov 2007]
A Rate-Based Congestion Control Scheme for Reliable Multicast Achieving TCP Fairness
TCP-friendly congestion control is a major requirement for reliable multicast to be deployed in the current Internet. This is because TCP responses to congestion control when it occurs, but multicast does not. [06 Dec 2007]
Constant Congestion Window Approach for TCP-Effect on Fairness
White Paper This paper indicates that a fixed congestion window performs better than a TCP Reno implementation. TCP was designed to work well in networks with low channel error rates. Wireless networks on the other hand are characterized by frequent... [06 Nov 2007]
Fairness and Congestion Control in LAN/WAN Protocol Relays
This paper addresses the problem of congestion control and fairness in relay systems for Connection Mode LAN/WAN interworking. To ensure congestion collapse avoidance and fairness against QoS parameters, a channel service algorithm and an... [06 Dec 2007]
Optimal TCP Congestion Control
An optimal decentralized congestion avoidance algorithm for TCP is developed by applying optimal control theory to an abstracted model of a bottlenecked TCP connection. A stochastic model of the cross-traffic, both TCP and non-TCP, on the... [06 Dec 2007]
