Configuration management policy based on cost model in OBS networks

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