OPS是光交换技术的发展目标，GMPLS是IETF提出的以数据业务为主的信息网络的统一控制框架。两者的结合为光网络提供了最优化的解决方案。在GMPLS控制协议下实现光域中的光分组控制标签提取、识别、缓存、路由等功能，能有效提高网络容量和灵活性。综合考虑信息承载效率、能量利用效率、传输性能以及方便交换节点中的光标签的处理等方面，本项目拟采用PPM-DPSK的光编码调制方式，将GMPLS标签写入光分组中，分析优化光标签的传输性能，研究PPM-DPSK光标签的全光处理技术，实现光分组的光域优化整形和PPM-DPSK光标签与数据净荷的全光分离。利用光纤光栅+增益饱和半导体光放大器组成的功能系统实现光标签信息的擦除以及光波长和射频副载波的重用。相关研究成果将对GMPLS/ OPS光网络设计提供相应的理论和试验依据。

OPS is the goal of optical switching technology. GMPLS is the union control frame of information networking which is advanced by IETF.Combining GMPLS and OPS would get optimized optical networking. Controlled by GMPLS, implementing the label of optical packet picking up, identifying, delaying and routing would efficiently improve the capability and agility of networking. According to the efficiency of information carrying, energy utilizing, transporting property and the all optical processing, the project using PPM-DPSK implement GMPLS optical label, analysis and optimize the transporting property. Researching all-optical-processing technology of PPM-DPSK label implement optical packet optimizing and PPM-DPSK lable separated from data payload. Based on fiber grating and saturated SOA erasure the information of optical label and implement the reusing of optical wavelength and subcarrier frequency. The researching results would provide theory and experiment proof to the GMPLS/OPS networking design.
