Implementation and Evaluation of SSBT for High-Performance Web Servers

Most of the researches have been concentrated on how to avoid and dissolve the network congestion, and only a few discussions on the performance improvement of the endhosts are recently made. We have already proposed a new architecture, which is called Scalable Socket Buffer Tuning (SSBT), to provide high performance and fair service for many TCP connections at the Internet endhosts. In this paper, we evaluate an effectiveness of our proposed algorithm through various kinds of implementation experiments. In the experiments, we confirm the behavior and effectiveness of the SSBT through both transport-layer benchmark results and application-layer benchmark results. In the transport-layer tests, we use the native TCP data transfer to evaluate SSBT performance. In the application-layer tests, we use HTTP data transfer from the Web server which transfer the data by TCP, considering the Web traffic on the Internet.
