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.
