摘要：
Two network restoration schemes are prestned for network survivability enhancement, link-based restoration and channel-based restoration. The genetic algorithm (GA) is used to optimize network resource assignments for the programming of survivable wavelength-division-multiplex (WDM) transport networks with link-based restoration. An integer linear programming (ILP) model is also presented to optimize network resource assignments for link-based restoration. For a large-scale mesh WDM optical transport network. The results show that, for link-based restoration, utilization of network resources for the Chinese mesh WDM transport network could be as high as 64%, which is an obvious improvement of the network resource utilization compared with self-healing rings and network protection schemes.
