自动交换光网络(ASON)作为构建下一代光网络的核心技术之一,相关的标准也正在迅速制定,但ITU-T 还没有给出其管理层面的体系结构与管理功能等相应的规范。该文从ASON网络资源管理的需求出发,提出了用于ASON跨区域端到端连接管理的网络层管理对象模型以及用于控制平面资源管理的对象模型。其中给出的控制层面管理模型可以实现控制网元以及控制通道的管理,控制层面的路由区域的划分以及控制模块的配置和性能监测管理等功能。
Automated Switched Optical Network (ASON) As one of the core technologies for building next-generation optical networks, relevant standards are rapidly being developed. However, ITU-T has not given any corresponding specifications on its management architecture and management functions. Based on the needs of ASON network resource management, this paper proposes a network layer management object model for ASON cross-region end-to-end connection management and an object model for control plane resource management. The given control plane management model can realize the functions of control network element and control channel, the control area of the routing area and control module configuration and performance monitoring and management functions.
