A time-slotted optical burst switching system and method therefor can support data transmissions for a constant bit rate (CBR) and at a variable bit rate (VBR) and improves a data transmission method at an edge node and a core node. Accordingly, it is possible to perform a data service for the constant bit rate and for a variable bit rate and to substantially prevent a delay due to a scheduling for a slot assignment at the core node by transmitting a burst control packet before the data burst to be transmitted at the edge node is generated in case of transmitting the data burst at the constant bit rate.
