Measured Comparative Performance of TCP Stacks

HARTs: high availability cluster architecture with redundant TCP stacks

Improving the availability of services of is a key issue for survivability of a cluster system. Lots of schemes are proposed for this purpose. But most of them aim at enhancing only the service-level availability or application specific. In this paper, we propose a scheme called High Availability with Redundant TCP Stacks (HARTs), providing connection-level availability by exploring the redunda...

Evaluating the Performance of TCP Stacks for High-Speed Networks

In this paper we present experimental results evaluating the performance of the Scalable-TCP, HS-TCP, BICTCP, FAST-TCP and H-TCP proposals for changes to the TCP congestion control algorithm to improve performance in highspeed network paths.

Bringing High-performance Networking to Hep Users

In a collaboration between the BaBar experiment and the UK e-Science network project, Managed Bandwidth – Next Generation, MB-NG, we demonstrated how the new TCP/IP transport protocol stacks could be used to achieve high performance data transport in a real HEP experiment. This paper reports on investigations of the performance of these TCP stacks and their use with data transfer applications s...

A Benchmark for the Performance of Time-varying Closed-loop Flow Control with Application to TCP

Closed-loop flow control protocols, such as the prominent implementation TCP, are prevalent in the Internet, today. TCP has continuously been improved for greedy traffic sources to achieve high throughput over networks with large bandwidth delay products. Recently, the increasing use for streaming and interactive applications, such as voice and video, has shifted the focus towards its delay per...
