采用光突发交换技术组建动态光虚拟专用网

Research of Using Optical Burst Switch Tech niques to Build the Dynamic Optical Virtual Private Network

光突发交换是光路交换和光分组交换的一个有效折衷方案,避免了两者的缺点,能很好的适应未来业务量爆炸式增长及业务的多样性和多变性的要求。光虚拟专用网业务使得企业能够在公网内部灵活地组建自己的网络拓扑,避免支出建设专用网络的沉重费用,同时使得运营商优化带宽的利用率,通过较少的投资获得更多的商业机会从而增加收入。把OBS技术应用于OVPN网络将使其具有更大的灵活性、安全性和可扩展性。这里介绍了OBS原理和功能,阐述了OVPN体系结构及参考模型,对采用OBS技术组建动态OVPN进行了探讨性研究。

OBS is a middle course of OCS and OPS,which can adapt to the development and ex plosive growt h of the data traffic.OVPN is a dou ble-win so-lu tion to the customers and p roviders.While the ap-pli ca tions of OBS in OVPN will make the network more f lexible,se cure and expansible.This paper in-tro duces the elements and funct ion of the opti cal burst switch techniques.At the same time the system arch i tecture and reference model of the optical virtual pri vate network are discus sed.At last dynamic OVPN service based on OBS technolo gy is pro posed and re-searched.
