Finding route and assigning wavelength often need to be considered together in the course of setting up light-paths for ASON ( Automatic Switched Optical Network ). This is called RWA ( Routing and Wavelength Assignment ). 在自动交换光网络(ASON)光路径的建立过程中,通常将寻找路由与分配波长结合起来考虑,称为路由和波长分配(RWA)问题。
Then based on this, the automatic routing of a three-sectioned and three-linked network is developed, with the general planning for the automatic routing of the multi-sectioned and multi-linked network proposed. 在单联络算法基础上又进行了三分段三联络接线的自动布局,并提出多分段多联络接线模式自动布局的一般性规划方法。
Intelligent Optical Network ( ION ), as the representative of Automatic Switching Optical Network ( ASON ) is the development trend of the next generation transport networks. Dynamic Routing and Wavelength Assignment ( RWA ) mechanism is one of the key technologies in IONs. 以自动交换光网络(ASON)为代表的智能光网络是下一代传送网的主要发展方向之一,路由与波长分配(RWA)是实现智能光网络的关键技术。
