In this paper an optical burst switching (OBS) architecture with optical code division multiplexing of label processing is analyzed. Just-in-time (JIT) signaling is considered as a higher performance option in relation to other protocols. The authors have developed a cost model to analyze and compare the cost of traditional electronic processing and optical processing of labels. We demonstrate that a decrease in burst loss probability and a gain in cost are obtained when optical label processing is used as compared to conventional electronic processing. It is also demonstrated that bursts with short length that would be blocked with electronic processing will be transmitted with optical processing. These results suggest that bufferless optical processing may be used to increase network capacity and to upgrade OBS network performance, in a cost-effective solution
