Thomas Anderson’s trailblazing network computing research has improved the understanding of Internet routing behavior and provided tools crucial to advancing Internet efficiency, reliability, and security. Anderson has developed novel techniques to understand, diagnose, and repair broken or pathological Internet routes essential to reducing the high number of service outages that occur daily around the world. Working with colleagues, Anderson was able to show that the shortest Internet path from point A to B is often not the direct path but rather one from A to C to B, and he developed a practical tool for identifying router-level paths in the reverse direction back to the source. He has also created protocols for addressing Internet denial-of-service attacks and reducing outages due to route protocol convergence.
