Network Tomography applied to TCP

Recent years have seen a dramatic growth of Internet in terms of connectivity, use and the development of novel network services. As this fast growth continues, it has become crucial to collect and analyze the data about a range of network functions, from low level internet path properties, to the performance of large scale Internet systems and applications. Such data analysis is what we deal in network tomography, and is on one hand crucial to understanding how networks and applications behave, and, on the other hand, is required to effectively design and provision future networks.

Throughput of a TCP connection, is precisely what many applications care about the most. It can be thought of as the application relevant manifestation of the under lying loss and delay behavior on the path. We would like to collect data related to loss, delay and RTT, and use it to model the evolution of the throughput of a TCP connection.
