Abstract: A data burst assembly apparatus includes a receiver to receive a packet from at least one source; a monitor to monitor a data traffic condition of a network; and a data burst generator to dynamically determine a value of a generation parameter for generating a data burst with respect to the packet received at the receiver according to the data traffic condition of the network, and to generate the data burst using the generation parameter value. A storage unit may be further included to store a mapping table defining generation parameter values mapped based on data traffic conditions. A data burst generator can read a generation parameter value mapped to a monitoring result from a mapping table and generate a corresponding data burst.

Abstract: An optical burst switching (OBS) system and a method using duplicate optical burst transmission is provided. In accordance with the present invention, optical bursts do not have the same priority when the duplicate optical bursts are transmitted in an OBS network so that a burst loss rate due to blocking can be reduced. Optical bursts do not have the same priority when the duplicate optical bursts are transmitted in an OBS network, so that a burst loss rate due to the blocking can be reduced. After an optical burst control packet is transmitted on a signal channel using a unidirectional reservation manner in the OBS, a problem such as optical burst loss due to the blocking can be prevented even when the optical burst is transmitted on a data channel after an offset time is elapsed without any response messages.
