The one-way reservation strategy in Optical Burst Switching (OBS) networks causes a blocking problem due to contention in resource reservation. In order to solve this problem, in this paper, we propose a configuration management policy based on the operation cost model. We develop the operation cost model based on DEB according to network status information changed by guaranteed Quality of Service (QoS) and the network status decision algorithm, and develop policy decision criteria for configuration management by providing an alternate path using bounded range of the sensitivity of this cost. Finally, throughout our theoretical and experimental analysis, we show that the proposed scheme has stable cost sensitivity and outperforms the conventional scheme in complexity.
