基于关系数据库的网络数据采集与管理

Using RDBMS in Netrwork Data Collecting and Management

1 引言网络管理是基于数据的。分布在网络各处的被管设备维护着大量的配置和状态信息,网络管理系统(NMS)通过网络管理协议(如SNMP、CMIP)与被管设备上运行的管理代理通信来获取这些信息,了解当前网络状况,记录和分析历史数据,进而采取相应的管理措施。可以说,数据是各类网络管理应用的基础:无论是运行监视、阈值告警、计费统计。

Data collecting serves as the data source of Network Management System(NMS). Its design determines the performance of NMSs. Nowadays,NMSs tend to use database to store and manage data. In this paper,we will study the category of network management information and other unique characteristics that present challenging database issues. Then we introduce a relational Network Database Model(rNetDB) ,which utilizes RDBMS in network data collecting and management. As an extension to the traditional RDBMS,rNetDB is an effective method that supports the mapping from MIB to relational table and enhances real-time performance in NMSs.
