摘 要: 光突发交换(OBS)是兼顾光电路交换和光分组交换优点的一种折衷方案,是未来光互联网的一种实现形式。在我们即将组建的光突发交换试验网中,IP(因特网协议)数据在边缘节点被组装成突发包,需要使用数据卡和控制卡分别处理数据分组和控制分组。因此,对处理控制分组的控制卡电路的优化设计和实现进行了描述。 Optical burst switching (OBS) is a compromising method combining the advantages of optical circuit switching and optical packet switching and is a promising optical internetworking form in the future. In the OBS test network we are establishing, IP data are assembled into burst packets and corresponding burst header packets are generated in edge nodes. These packets need to be processed and transmitted by data cards and control cards respectively. In this case, the circuit design and implementation of control card used for processing control packets are described.
