Network communication has become a part of everyday life, and the interconnection among
devices and people will increase even more in the future. Nevertheless, prediction of Quality …

We consider a simple model of parallel TCP connections defined as follows. There are N
connections competing for a bottleneck of fixed capacity. Each connection is assumed to …

In end-to-end data transfers, there are several factors affecting the data transfer throughput,
such as the network characteristics (eg, network bandwidth, round-trip-time, background …

RPS is a publicly available toolkit that allows a practitioner to straightforwardly create flexible
online and offline resource prediction systems in which resources are represented by …

Wide area data transfers play an important role in many science applications but rely on
expensive infrastructure that often delivers disappointing performance in practice. In …

The comparison between TCP and UDP tunnels have not been sufficiently reported in the
scientific literature. In this work, we use OpenVPN as a platform to demonstrate the …

DualPats exploits the strong correlation between TCP throughput and flow size, and the
statistical stability of Internet path characteristics to accurately predict the TCP throughput of …

Disk-to-disk wide-area file transfers involve many subsystems and tunable application
parameters that pose significant challenges for bottleneck detection, system optimization …

Wide area data transfer may be a major bottleneck for the end-to-end performance of
distributed applications. A practical way of increasing the wide area throughput at the …

Wide-area transfer of large data sets is still a big challenge despite the deployment of high-
bandwidth networks with speeds reaching 100 Gbps. Most users fail to obtain even a …
