摘要 该文针对动态变化的业务请求,提出了分光节点的鲁棒配置算法,解决全光网络中光多播时分光节点最优配置问题。文中的测试验证了,利用这种鲁棒算法配置分光节点,与静态算法相比可以使资源的消耗在各种业务请求情况下都相对较优,稳定性好,总的资源消耗少,更符合实际。 In this paper, with uncertain demands, a robust optimization strategy is proposed to optimally solve the splitter placement problem for multicast in all-optical networks. The test in the paper shows that using robust strategy, the resource provisioning of each scenario is closer to the optimal resource consumption, more robust, less resource consumption and more practically than the static solution.
