【摘要】：IP为代表的数据业务的持续快速增长对光传送网提出了越来越高的要求,传统的同步数字传送网SDH和波分复用WDM网络尽管已经将传输带宽提高到较高的水平,但是仍然存在包括灵活性和扩展性等方面的缺点。未来的光网络不仅需要解决带宽问题,而且要有灵活提供带宽的能力,能够在满足用户差异化的业务需求的同时实现网络资源的高效分配。以自动交换光网络ASON为代表的智能光网络能够智能化地自动完成光网络交换连接功能,得到了广泛的认同。所以现在传输网中ASON的有关技术是当下研究中的重要部分,本文主要探讨的是ASON的有关技术和它在南京电信骨干传送网中的应用。本篇文章给出了ASON的基本原理、体系架构、分层网络模型、业务层次模型等,着重分析了ASON各类客户信号映射方法及其与网络模型的对应关系。然后详细分析和讨论了ASON网络规划相关技术,包括网络信息收集、网络业务分析、网络结构设计、网络容量规划和容量验证及安全性分析等。在此基础上,结合南京电信传送网络的实际情况,分析并给出了ASON网络规划和设计方案。
[Abstract]:The continuous rapid growth of data services represented by IP has put forward higher and higher requirements for optical transport networks. The traditional synchronous digital transport network (SDH) and wavelength division multiplexing (WDM) networks have raised the transmission bandwidth to a higher level. But there are still shortcomings including flexibility and extensibility. The future optical network not only needs to solve the problem of bandwidth, but also has the ability to provide bandwidth flexibly, which can meet the needs of users' differentiated services and realize the efficient allocation of network resources at the same time. The intelligent optical network, represented by the automatic switched optical network (ASON), can intelligently complete the switch connection function of the optical network, which has been widely recognized. So the related technology of ASON in the transmission network is an important part of the current research. This paper mainly discusses the related technology of ASON and its application in Nanjing Telecom backbone transmission network. In this paper, the basic principle, architecture, hierarchical network model and business hierarchy model of ASON are given. The mapping method of ASON customer signal and its corresponding relationship with network model are analyzed. Then, the related technologies of ASON network planning are analyzed and discussed in detail, including network information collection, network traffic analysis, network network structure design, network capacity planning, capacity verification and security analysis. On this basis, combined with the actual situation of Nanjing Telecom transport network, the ASON network planning and design scheme are analyzed and given.
