PURPOSE: A control packet for an OBS(Optical Burst Switching) network and a method for generating a data burst are provided to decrease the size of a requested burst by limiting the maximum queuing delay time and increasing a data burst use rate in a burst input traffic. CONSTITUTION: If a timer value is greater than a threshold value, or the timer value is less than the threshold value and a size value of a queue is greater than a change condition value(Qlow), a new burst is generated(S12,S14,S16). If the size value of the queue is greater than a change condition value(Qhigh)(S18), a count number is increased by 1(S30). If the size value of the queue is less than the change condition value(Qlow), the count number is decreased by 1(S40). A crossover count number is compared with an upper limit value and a lower limit value(S32,S34,S42,S44). If the crossover count number is greater than the upper limit value, a burst size is increased(S36). If the crossover count number is greater than the lower limit value, the burst size is decreased(S46).
