摘要：

Optimising network performance is key to high bandwidth data transfers required for a Tier-2 site. We describe the techniques we have used to obtain good performance. Monitoring plays a key part, as does the elimination of bottlenecks and tuning TCP window sizes. Multiple parallel transfers allowed us to saturate a 1 Gbit/s link for 24 hours - whilst still achieving acceptable download speeds. Source based routing and multiple data transfer servers allowed us to use an otherwise unused "resilient" link
