Embodiment Construction
[0018] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0019] For the existing routing bandwidth allocation method in the optical path network, because the reserved service needs to meet the transmission time requirements, it may cause a large number of bandwidth fragments in the optical wavelength transmission channel, and at the same time make the load on the active transmission optical path unbalanced. The number of services is too small and the bandwidth utilization rate is low. The present invention designs a bandwidth adjustment-based dredging of light-loaded optical paths to transmit reserved services to relatively heavy-loaded optical paths, thereby turning off light-loaded optical paths to save energy. The algorithm is composed of three parts. The routing weight matrix of the optical network is constructed to record the pre-allocated occupancy of the transmission time slots on the optic...
