【摘要】：现代社会对光通信网络的依赖性越来越大,一旦中断,不仅会给企业造成巨大的经济损失,对于社会和用户个人的破坏性有可能也是无法估量的。同时,在开放的市场条件下,竞争进一步加剧,客户更加关注通信网络的安全性和可靠性,更加注重自身业务的快速恢复,网络可靠性成为吸引客户至关重要的因素,也是我们提高服务质量,保证和谐客户关系的重要方面。此外,随着国家信息化进程的加快实施,通信业务量增长很快,对通信网络的安全性和生存能力提出了更高的要求。因此,如何实现通信网络的有效保护和恢复是我们在运行维护过程中必须考虑的一个重要因素,而网络的保护与恢复对于整个网络的安全性和生存能力有着重大的影响。本课题研究主要目的：通过分析理解掌握不同传输网络类型的保护实现方式和机理,提出不同网络、设备类型自愈环实现自愈恢复的原理和方法,总结实际传输维护工作中的体会和经验,希望对今后的工作能有比较大的指导和帮助。本课题研究的主要内容：分析SDH自愈环保护、自动切换系统保护、DWDM系统和ASON智能光网络系统在现网中实现保护的机理和方法。尤其是对DWDM波分系统接入光纤自动切换系统实现线路保护过程,进行详细的阐述。
[Abstract]:Modern society is becoming more and more dependent on optical communication network. Once interrupted, it will not only cause huge economic losses to enterprises, but also may be immeasurable to society and individual users. At the same time, under open market conditions, As the competition intensifies, customers pay more attention to the security and reliability of the communication network, and pay more attention to the rapid recovery of their own business. Network reliability becomes a crucial factor in attracting customers, and it is also for us to improve the quality of service. In addition, with the rapid implementation of the national informatization process, communication traffic is growing rapidly, which puts forward higher requirements for the security and survivability of the communication network. How to realize the effective protection and restoration of the communication network is an important factor that we must consider in the course of operation and maintenance, and the protection and recovery of the network have a great influence on the security and survivability of the whole network. The main purpose of this research is: through analyzing and understanding the protection realization mode and mechanism of different transmission network types, putting forward the principle and method of self-healing recovery of different network and equipment type self-healing ring. This paper summarizes the experience and experience in actual transmission and maintenance, and hopes to provide more guidance and help for future work. The main contents of this research are: analysis of SDH self-healing ring protection, The protection mechanism and method of ASON intelligent optical network system and automatic handover system protection system are discussed in detail, especially the implementation of DWDM wave subsystem access to optical fiber automatic switching system.
