Abstract
This paper analyzes the limits of effective throughput for TCP segments through an optical burst switching (OBS) network. Wavelength conversion and deflection routing are considered as contention resolution methods. The work shows that there is a strong interaction between the load dependant contention, leading to segment losses or segment reordering and the TCP congestion avoidance mechanisms. It also provides a consistent treatment of OBS contention resolution and TCP congestion avoidance.
