Large distributed collaborations like the EU (European Union) Data Grid
Project will require the ability to move vast quantities of data across wide area networks (WAN) as efficiently and effectively as possible. However, obtaining good TCP (Transmission Control Protocol) throughput across a wide area network usually requires some tuning. This is especially true in high-speed networks, where, even without congestion, an application might see only a small percentage of the total available bandwidth.
This talk will start with a brief introduction on how TCP works. Next, it will describe analysis tools and techniques required to obtain good throughput. Finally, the talk will cover some general methods for improving application performance in a high-speed WAN, or 'Grid', environment.
