自动交换光网络（ASON）在光传输网络之上引入控制平面,可以支持动态波长连接的建立, 动态地分配网络资源,因此一出现就引起了广泛的关注。ITU-T等组织定义了大量关于控制信令方面的规范,但是没有给出任何与网络管理方面相关的内容。本文针对ASON网络的特点,提出了适合ASON网络的基于CORBA技术实现的域间网络管理方案,然后对ASON的基本管理功能需求进行了分析,其中着重分析了ASON引入的控制平面的管理需求,为控制平面管理功能的实现做出了理论指导。最后,对如何应用CORBA技术实现网管系统进行了分析。
Automatic Switched Optical Network (ASON) introduced in the optical transport network above the control plane, can support the establishment of dynamic wavelength connection, the dynamic distribution of network resources, so the emergence of a widespread concern. Organizations such as the ITU-T have defined a large number of norms regarding control signaling, but did not give any content related to network management. According to the characteristics of ASON network, this paper proposes an interdomain network management scheme based on CORBA for ASON networks, and then analyzes the basic management functions of ASON. The requirements of management plane introduced by ASON are emphatically analyzed as The realization of control plane management has made theoretical guidance. Finally, how to use the CORBA technology to realize the network management system is analyzed.
