光分组交换技术研究

Optical Packet Switching Technology

光分组交换技术克服了限制光网络发展的电子瓶颈,具有最小的交换粒度,是一种理想的光交换技术．文中介绍了光分组交换的基本原理和关键技术,并总结了在光分组交换中——副载波标签产生,竞争解决, 全光时钟恢复和2R再生技术中所开展的研究工作和取得的研究成果．

Optical packet switching can conquer the electronic bottleneck that confines the development of optical networks. The switching granularity of optical packet switching is smaller than that of optical circuit switching or optical burst switching. The principle and key technologies of optical packet switching is introduced in this paper. The research results are shown, including the generation of single-sideband subcarrier label, contention resolution, all-optical clock recovery and 2R regeneration.
