摘　　要：近年来 ,随着Internet的出现和繁荣 ,IP业务量呈现爆炸式的增长 ,同时 ,WDM由于其巨大的带宽和成熟的技术正成为未来的主导传输技术。因此 ,人们提出了光因特网的概念来将IP和WDM两种技术有效结合起来。随着光因特网概念的提出 ,光因特网中的控制和管理技术也得到了广泛的研究 ,不过当前的研究主要集中于对控制技术的研究。但是 ,当前控制平面方法还有很多问题有待解决 ,同时 ,要满足这个新型网络最重要的要求即实现业务的快速提供和故障恢复 ,采用管理平面的方法也同样可以实现。光因特网网络管理不仅要能够对IP网和光网络进行管理 ,还要能够对两种技术进行集成的管理 ,以更好地利用和维护网络资源。本文主要研究光因特网中的网络管理技术 ,提出了光因特网管理模型、管理体系结构以及管理信息模型 。With the appearance and prosperity of Internet in recent years,IP traffic is increasing explosively.At the same time,WDMis becoming the dominant transmission technology of tomorrowdepending on its huge bandwidth and maturity in technology.Thereby,the concept of optical Inˉternet was proposed to combine these two most promising technologies together.With the appearance of the concept of optical Internet,much research has been done in the control and management of optical Internet,but focus has been on the study of control of optical Internet so far.However,there are many problems need to be resolved in this control plane method.Meanwhile,the management plane method is also a considerable way of realizing the most important requirement that provides fast service provisioning and restoration of this new network.The management of optical Internet not only needs to manage the existing IP network and WDMnetwork,but also to manage both of themintegratedly.By this means,this method can make good use of and maintain the network resources.This paper mainly studies the network management in optical Internet.Network management model,management architecture and the management information model of optical Internet are brought forward,and finally the implementation ways of the transport of management information are also introduced.
