【摘要】 自动交换光网络(ASON)中具有灵活多样的生存性机制,根据业务对故障恢复的可靠性要求,可以为其提供适当的保护恢复机制。文章提出了一种在ASON中实现的分级服务方案,首先以恢复时间为标准定义出不同的生存性等级,然后给出了实现该方案的功能模块及流程图,最后对该方案进行了仿真分析。更多还原

【Abstract】 There are many kinds of survivability in ASON that can satisfy the different requests of the clients. In this paper, a differentiated protection/restoration scheme in ASON is proposed. Firstly, some SL degrees are defined based on the demands for recovery time of the clients and the available resources in network, secondly, the protection/restoration modules of control plane in ASON are designed and analyzed, at last, we simulated it at the simulation platform and the simulation results are analyzed.更多还原
