… to reduce the burst loss rate. Although the retransmission scheme can reduce the burst loss
rate greatly, the retransmitted traffic will introduce the extra traffic load into the networks, and …

… retransmitted burst incurs an extra retransmission delay, bursts that are sent after the contending
burst … case with OBS retransmission, the successfully retransmitted bursts are treated …

… the fast retransmit algorithm, decreases with the number of packets per flow and burst. The …
is not critical, when the deflection ration on burst level is kept in strict borders. In this case, the …

… In this subsection, we consider two possible ways to reduce the loss recovery time and
the blocking probability of retransmitted burst: namely, early retransmissions and optimized …

… network are retransmitted at the OBS layer. The retransmission scheme aimed to reduce
burst loss … In the retransmission scheme, the retransmitted bursts follow the same route as the …

… We propose also another protocol to retransmit the lost bursts. Although these propositions
could improve OBS and keep the loss under control, the loss is still there, and some …

… schemes on optical burst reordering and estimate the TCP performance. They measure the
amount of optical burst … the buffer size and the retransmission ratio. Single layer studies on …

… In the retransmission scheme, our proposal collects the conditions of suitable indexes
from intermediate nodes with the NACK message. Through simulations, we confirmed the …

… Note, that in this scheme, it is possible that a burst may be lost if the control packet is not …
along the burst’s path. The OBS architecture, however, does not retransmit lost bursts. This job …
