摘　　要：基于SNMP协议的网络数据采集是TCP/IP模型网络管理的基础,是互联网环境下网络管理的主要标准。但在应用过程中也存在很多具体问题,特别是在轮询过程中,缺乏统一标准,实现过程中存在效率低、附加流量大等问题,根据现有的网络环境,提出了一种基于优先级控制的轮询方法。该方法采用统计原理,可以根据网络状况动态修正在轮询过程的优先级别,根据不同优先级控制轮询过程的排队。通过测试系统的分析,该方法可以在一定程度上提高轮询的效率,减少关键对象的响应时间,达到有效管理的目的。SNMP-based data collecting is fundamental for TCP/IP network management, and that is the main standard about network management in Internet. But there is much specific problem in the application process, especially in polling process, such as the lack of u niform standard, the low efficiency phenomenon, the additional communication flows. According to the existing network environment put forward a polling method based on the priority control. The method uses the statistical principle,can fix polling priority level according to the dynamic network status, and can control queue polling based on different priority level. Through the analysis of the testing system, the algorithm can improve the efficiency of the polling, and reduce the response time of the key object. This algorithm can achieve the pur- pose of effective management.
