Abstract

This paper describes a tool to diagnose network performance problems commonly affecting TCP-based applications. The tool, pathdiag, runs under a web server framework to provide non-expert network users with one-click diagnostic testing, tuning support and repair instructions. It diagnoses many causes of poor network performance using Web100 statistics and TCP performance models to overcome the lack of otherwise identifiable symptoms.
