IP数据业务导致数据网的功能、结构和业务组成发生很大变化,IP业务已经向大颗粒方向发展,同时IP业务对传输网络可靠性和安全性提出了更高的要求。提出了一种改进保护方法,解决了大颗粒数据业务在传输网络承载保护方式中存在的缺陷,同时,对大颗粒业务(尤其是IP电路)的安全性进行保护方法的检测,从而提高了业务和网络的安全性,最后介绍了保证大颗粒业务电路正常运营必须加强的日常维护要求。
IP data services lead to great changes in the function, structure and service composition of the data network. IP services have been developed towards large particles. Meanwhile, IP services have put forward higher requirements on the reliability and security of transmission networks. An improved protection method is proposed to solve the shortcomings of the large granular data service in the transport network bearer protection mode. At the same time, the protection of large granular service (especially IP circuit) is detected, which improves the service And network security, finally introduced to ensure the normal operation of large particle business circuit must be strengthened routine maintenance requirements.
