The fairness (or TCP-friendliness) of recent high-speed TCP proposals for high bandwidth-delay product networks is generally poor. We believe that the lack of the TCP-friendliness of high-speed TCP proposals stems from their ineffectiveness in detecting competing TCP ¤ows. We suggest a competition detection mechanism for a single TCP ¤ow to detect the presence of competing TCP ¤ows and propose ...

TCP tunnel is a technology that aggregates and transfers packets sent between end hosts as a single or multiple TCP connections. By using a TCP tunnel, the fairness among aggregate flows can be improved and several protocols can be transparently transmitted through an Internet firewall. However, since most applications running on end hosts generally use TCP, two TCP congestion controls (i.e., e...

The existing TCP (Transmission Control Protocol) is known to be unsuitable for a network with the characteristics of high BDP (Bandwidth-Delay Product) because of the fixed small or large buffer size at the TCP sender and receiver. Thus, some trial cases of adjusting the buffer sizes automatically with respect to network condition have been proposed to improve the end-to-end TCP throughput. ATB...

this article investigates the end-to-end TCP performance in the scenario where WCDMA is employed as the access link. Unlike previous work, we incorporate the impact of Internet loss rate and delay into the study. The performance of TCP over WCDMA is studied from several aspects: the TCP protocol configurations, the different variant of TCP protocols, the interaction of TCP and RLC layer protoco...

FAST TCP is Fast Active queue management Scalable Transmission Control Protocol. FAST TCP is an alternative congestion control algorithm in TCP. It is designed for high speed data transfers over large distance. FAST TCP is assumed to be the “successor” of TCP. Lot of people already worked on this subject. Their research work and results yield a new dimension for the entertainment and scientist ...

Test Case Prioritization (TCP) techniques perform better than other regression test optimization including Suite Reduction (TSR) and Selection (TCS). Many TCP are available, their performance is usually measured through a metric Average Percentage of Fault Detection (APFD). This value-neutral because it only works well when all cases have the same cost, faults severity. Using APFD for evaluatio...

Powders based on β-tricalcium phosphate (β-TCP) containing sulphate groups at up to 12.0 mol.% were synthesised by chemical precipitation from aqueous solutions. The obtained materials characterised X-ray phase analysis, Fourier transform infrared spectroscopy, measurement of specific surface area, scanning electron microscopy, energy dispersive synchronous thermal mass spectra investigations a...

Many applications want to use TCP congestion control to regulate the transmission rate of a data packet stream. A natural way to achieve this goal is to transport the data packet stream on a TCP connection. However, because TCP implements both congestion and error control, transporting a data packet stream directly using a TCP connection forces the data packet stream to be subject to TCP’s othe...

The aim of this work was to evaluate the effect of in vitro alendronate (AD) release behavior through polycaprolactone (PCL) coating on in vivo bone formation using PCL-coated 3D printed interconnected porous tricalcium phosphate (TCP) scaffolds. Higher AD and Ca(2+) ion release was observed at lower pH (5.0) than that at higher pH (7.4). AD and Ca(2+) release, surface morphology, and phase ana...

The demand for fast transfer of large volumes of data, and the deployment of the network infrastructures is ever increasing. However, the dominant transport protocol of today, TCP, does not meet this demand because it favors reliability over timeliness and fails to fully utilize the network capacity due to limitations of its conservative congestion control algorithm. The slow response of TCP in...
