In this paper we analyze 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 TCP congestion avoidance mechanisms and the load dependant contention in the OBS network. It provides for the first time a consistent treatment of OBS contention resolution and TCP congestion avoidance.
