Patent ID: 8068484

Claim:
A method for transmitting a burst data (BD) received at an interval of an offset time from a burst control packet (BCP) containing information pertaining to the offset time of the BD by a node in an optical burst switching (OBS) network, the method being performed by the node and comprising: defining a void filling time within the offset time, wherein the void filling time is at least long enough to fill a new BD between a first in time BD and a second in time BD, and the new BD is generated by the node; determining whether a second in time BCP corresponding to the second in time BD is received within the void filling time after the reception of a first in time BCP corresponding to the first in time BD; and transmitting the new BD after transmitting the first in time BD by delaying the first in time BD as long as the void filling time if it is determined that the second in time BCP is not received within the void filling time, wherein the offset time is a temporal difference between a receiving time point of the BCP and a receiving time point of the BD.
