介绍一种新的光标记交换技术,它是利用光载波的抑制来产生具有固定频率间隔的双波长光波,并对这两路光波分别进行调制,以加载光标记和光数据载荷。在网络的节点处使用波长变换技术进行标记交换。该技术结构简单,易于实现,克服了现有的光标记交换技术中的一些不足之处。
A novel technique for optical label switching, it generated two longitudinal modes with a fixed frequency spacing using optical carrier suppression. Then we modulated the two modes respectively to generate optical label and payload. In the node, we used wavelength conversion technique for label swapping. The system of this technique is simple and easily to achieve. It overcomed some drawbacks in previous optical label switching techniques.
