Congestion Pricing For Highways
White Papers As commuters in most large urban areas can affirm, highway congestion has become a serious problem that carries high costs in terms of time. It is unlikely that the United States could ever "build its way out of congestion," even with massive...

Congestion Control: SCTP Vs TCP
White Papers This paper characterizes an inefficiency in the current speciation of SCTP's congestion control, which degrades performance (more than necessary to be 'TCP-friendly') when there are multiple packet losses in a single window.

Congestion Controlled Adaptive Lightweight Multicast In Wireless Mobile Ad Hoc Networks
White Papers The use of contention-based MAC protocols combined with hidden terminal problems make multi-hop wireless ad hoc networks much more sensitive to load and congestion than wired networks or even wireless cellular networks.

"De-Randomizing" Congestion Losses To Improve TCP Performance Over Wired-Wireless Networks
White Papers Currently, a TCP sender considers all losses as congestion signals and reacts to them by throttling its sending rate. With Internet becoming more heterogeneous with more and more wireless error-prone links, a TCP connection may unduly throttle its...

Congestion And Corruption Loss Detection With Enhanced-TCP
White Papers This paper presents how TCP is tuned to differentiate between corruption and congestion losses. In the Internet area, the Transmission Control Protocol (TCP) is the most commonly used transport protocol.

TCP Symbiosis: Congestion Control Mechanisms Of TCP Based On Lotka-Volterra Competition Model
White Papers This paper proposes TCP Symbiosis, which has a robust, self-adaptive and scalable congestion control mechanism for TCP. The method is quite different from existing approaches. The paper changes the window size of a TCP connection in response to...

Congestion Control Mechanism Of TCP For Achieving Predictable Throughput
White Papers This paper proposes a congestion control mechanism of TCP for achieving predictable throughput. It does not mean one can guarantee the throughput, while one can provide the throughput required by an upper-layer application at high probability when...

Congestion Control Algorithms Of TCP In Emerging Networks
White Papers This paper examines some of the challenges faced by the congestion control algorithms of TCP in emerging networks. First, it proposes TCP with delayed congestion response (TCP-DCR), for improving performance in the presence of non-congestion events.

A New TCP Congestion Control With Empty Queues And Scalable Stability
White Papers This paper describes a new congestion avoidance system designed to maintain dynamic stability on networks of arbitrary delay, capacity, and topology. When a congestion measure signal from links to sources is available, the system can satisfy also...
