Summary :

Optical Burst Switched (OBS) networks are considered as promising candidates for the next generation network architecture which does not need high-speed switch technologies. In OBS networks, contention resolution is one of the significant problems. Generally, setup reservations are operated per burst in OBS networks. To transmit multiple successive bursts successfully, the effective wavelength reservation must be implemented and enhanced network performance must be realized. In the proposed method, when an optical burst is generated and its destination is the same as that of the preceding burst or the path until the destination includes the entire path of the preceding burst, the subsequent burst is assigned to the same wavelength as the preceding burst and transmitted sequentially. The main aim in the proposed method is the efficient use of wavelength resources and the reduction of burst loss probability. We simulate and evaluate the effectiveness of the proposed method. As a result, it is verified that the proposed method can reduce the burst loss probably.
