英文摘要： According to the bottleneck restriction and theinfrastructure challenge of the information network, and taking the high efficiency,low power consumption, high probability of extention, and high reliable of thenetwork into account, this project aims to explore the cognition theory and implmenetation mechanism of high spectrum efficient all optical networks, first proposes the novel idea of spectrum engineering and cognitive spectrum control, study the spectrum engeering strategies in flexible grid optical networks, access control model based on service authorization cognition, spectrum allocation theory on demand based on bandiwidth property cognition, and spectrum adjustment and defragmentation method based on resource state cognition. From this, the science problem of spectrum cogintion and spectrum utilization can be solved. This project also aims to make innovation and breakthrough in system structure, control mechanisms, and service application in all optical network,develop testbed of flexible grid optical networks and set up experimental platform to make service demonstrations, and achieve a breakthrogh in the development of intellectual property rights andstandard contributions.
