|Description: ||This paper describes some methods for contention resolution in bulk ﬂow TCP routing in optical IP network through simulation. The various domains such as wavelength, time and space with respect to bulk ﬂow TCP to resolve contention are studied. The results show that the ﬂow based transmission under wavelength domain exhibits only the probability of contention is 27%. At the same time, the contention can be resolved to maximum of 97% when we increase the ﬂow size. This also shows a signiﬁcant improvement in performance that is the percentage to resolve contention on an average touches more than 80% when the system operates under lower wavelength region. The results also reveal that the probability of occurring contention is only 47% for a transmitter load of 0.7. But in the case of byte based transmission, the probability of occurring contention is 63% for the same transmitter load. We have also studied the packet loss rate, ﬂow loss rate for ﬁxed size and variable size ﬂows. For a transmission of 200 packets, we achieved a ﬂow loss rate of 0.038 for a variable size ﬂow and a ﬂow loss rate of 0.043 for a ﬁxed size ﬂow. But in the case of packet transmission mode, the packet loss rate is 0.063.|
