随着网络通信技术的发展,通信业务类型呈现宽带化、IP化趋势,承载业务的传送网的发展要满足宽带化、分组化、扁平化和智能化的需求,OTN网络就在这样的趋势下应运而生并得到了广泛的应用。基于电力通信网超长距传输的特点,从OTN网络设备配置中的网络拓扑、光层经验参数和域间对接三个方面进行了探究,并提出了相关建议来指导实际OTN部署。
With the development of network communication technology, the types of communication services are becoming broadband and IP-based. The development of transport networks carrying services needs to meet the requirements of broadband, packetization, flattening and intelligence. The OTN network is under such a trend Came into being and has been widely used. Based on the characteristics of over-long-distance transmission in power telecommunication network, this paper explores three aspects of network topology, optical layer experience parameters and inter-domain interoperation in OTN network equipment configuration, and puts forward relevant suggestions to guide actual OTN deployment.
