英文摘要: The bandwidth variable optical switching technology is the most promising way for optical network to conquer the growing traffic demand, meet the long reach requirement, ease control and management difficulty, and support multi rate service transmission. This proposal is going to meet the trends of high spectrum efficiency transmission and intelligent control and management, and focus on the adaptive issues in bandwidth variable optical switching network (BV-SON). In order to reveal the complexity of adaptive control approach, we analysis the demands of adaptive network modification, the high coupling property of adaptive optimization approach and its technique details. The complex coupling property of objects in the adaptive optimization approach, the model of adaptive optimization approach in system level, and adaptive optimization technique with whole network view are the major basic problems we are approaching. System control theory and optimal decision theory are introduced to model the adaptive optimization approach in BV-SON, design function block of optimal decision of adaptive approach and coordinating adaptive control algorithm. We also develop the testbed of adaptive approach to evaluate the efficiency of adaptive theory we studied and algorithms.
