运营商网络监控系统高可用性设计及应用

High Availability Design and Application of Network Monitoring System of ISP

中国电信NetCare服务,是中国电信统一建立面向企业客户的云网一体化监控平台(监控对象包括客户端网络设备、云端应用及虚拟资源、专线及互联网线路),为企业提供网络层、传输层以及应用层在内的监控管理和分析的业务.该业务为中国电信政企客户提供服务,对于系统的高可用性有着很高的要求.影响一个系统的高可用性有硬件、网络、操作系统、数据库、中间件、应用本身等多个方面,本文着重讨论NetCare系统应用层的高可用性实践,通过实测及合理估算数据计算得出系统的整体可用性:不包含异地灾备系统时,系统可用性为99.9978%;包含异地灾备系统时,系统可用性为99.45%.

China Telecom NetCare service is a unified cloud network integrated monitoring platform.The system monitors client’s network device,cloud applications,virtual resources,VPN and Internet.It is developed by China Telecom to provide the monitoring management and analysis services of network layer,transmission layer and application layer for enterprises.It serves the government and enterprise customers of China Telecom,and has very strict requirements for availability of the system.The high availability of a system is influenced by hardware,network,operating system,database,middleware,application itself and other aspects.This study focuses on the application layer’s high availability of the NetCare system,and calculates the availability of the system with actual measurement and reasonable estimation of data.Finally,we come to a conclusion according to the paper:when the remote disaster recovery system is excluded or included,the whole system’s availability is 99.9978%and 99.45%respectively.
