基于SNMP的全光网故障管理子系统的设计与实现
摘要
数据通信业务量的爆炸性增长,对数据传输网带宽提出越来越高的需求。当骨干网和城域网需要更多的带宽时,波分复用WDM已被证明是较铺设新光纤更便利的高效解决方案。由于传统交换节点的光-电-光转换数字交换带来的效率瓶颈,全光网成为骨干网和城域网的发展方向。它是将点到点的波分复用系统用光交叉(OXC)互连节点和光分插复用(OADM)节点连接起来,组成的光传送网,全程不需要任何光电转换。随着密集波分复用DWDM技术的规模应用和全光网的普及,越来越多的通信业务集中到较少的节点和线路上,每一条光纤所承载的通信量及实质带来的营收都不断地增长,因此对其所在的光网络的可靠性也提出了越来越高的要求。
本文首先综述了全光网络的架构、实现和故障管理机制,回顾了主要的网络管理模型和协议,重点分析了光交换节点OXC和OADM产品的实现机制。
基于上海御威通信的OADM设备,对全光网络的网络管理和自愈环保护机制进行比较深入的研究和探讨。针对OADM产品组成的全光网络,提出了故障的分类、检测、定位和管理机制,特别对OADM产品的链路恢复机制进行了一些研究。
结合全光网的故障管理需求,论文探讨了基于全光网的SNMP故障管理的实现机制以及故障分析功能。对基于全光网的SNMP故障管理系统的功能模块进行了划分、对全光网故障的管理和故障处理流程进行了设计。实现了一个基于SNMP的全光网故障管理子系统,提供了一个稳定可靠、可管理的光传送网络。
The explosive growth of the data communication service requires higher data transmission bandwidth. When the backbone network and metropolitan area network demand more bandwidth, Wavelength division multiplexing-WDM has been proven to be more convenient and efficient solution than paving the new optic fiber. Due to the bottleneck of photon-electron- photon conversion in traditional digital switch node, All-optical is becoming the developing target of the backbone network and metropolitan area network. All-optical network is composed by photonic node, such as OXC and OADM. With the full-scale application of DWDM and the prevalence of the all-optical network, more and more communication service concentrates on fewer nodes and lines. The communication and revenue of every fiber is growing, so the lines in all-optical network require more and more reliability.
The paper firstly summarizes the all-optical network architecture, implementation and fault management mechanism, and overviews the mainstream network management models and protocols, and then puts more emphasis on analyzing of the implementation mechanism of the optical switching node product, such as OXC and OADM.
Based on OADM equipment of Shanghai Y-WAVE Telecom Communication, this paper makes an in-depth study and discussion in network management and self-healing ring protection mechanism in all-optical network. The mechanism of fault classification, detection, location and management is given for the all-optical network composed by OADM product, particularly in the research of line recovery mechanism of the OADM product.
In combination with the demand of fault management in the all-optical network, this paper makes a discussion in implementation mechanism of SNMP fault management and fault analyzing function in the all-optical network, makes design in the subdivision of functional module, fault management and processing flow of the all-optical network, provides a high-reliability and manageable optical network.
