Web100

The Web100 project is a fantastic solution for those looking to optimize their TCP applications' performance. This software environment has been designed to ensure that applications can run at 100% of the available bandwidth, regardless of the network's size. While the national high-performance network infrastructure has significantly improved both in accessibility and bandwidth, users and researchers may still struggle to take full advantage of this infrastructure.

Without expert intervention from network engineers, users often cannot achieve even 10 Mbps single-stream TCP transfers, despite the underlying network infrastructure supporting data rates of 100Mbps or more. This subpar performance is often down to two factors. Firstly, the host system software, predominantly TCP optimized for low-bandwidth environments. Secondly, the lack of tools and effective instrumentation to diagnose performance issues.

Thankfully, the Web100 project was created to address these concerns. Firstly, it solves the host system software issue by automating TCP buffer tuning. This work has already been merged with the main-line Linux kernel and is available in recent releases. Secondly, a set of TCP instruments has been created to combat the lack of effective instrumentation and tools for diagnosis. These instruments have been defined in an IETF internet-draft and implemented within Linux using the Web100 kernel patch.

In conclusion, if you need high-performance network infrastructure that maximizes TCP application performance, then look no further than the Web100 project. Its automated TCP buffer tuning and TCP instruments to diagnose performance issues are a game-changer, offering users and researchers the opportunity to take full advantage of high-performance networks without needing expert intervention from network engineers.
