基于Net-SNMP的多业务网管代理扩展的设计与实现

Design and Implementation of Multi-service Agent Extension Based on Net-SNMP in Network Management System

随着网络技术的标准化和基于网络的应用不断丰富和增多,网络管理的研究方向越来越侧重于对业务的管理,研究和设计统一的综合业务网管系统日益显示出重要性。被管业务主要是通过代理机制同网管系统交互以实现接收来自网管系统的查询请求以及告警事件的主动上报,而在实际系统中业务种类众多,功能机构也各不相同,因此设计简单可靠、低成本、扩展性高的代理扩展方法是保证综合业务网管系统高效可靠的一个重要元素。文章提出了一种基于Net-SNMP的多业务网管代理的设计与实现方法:在一个具体的网络管理节点下利用Net-SNMP作为Master Agent,而将subagent嵌入到具体的业务系统,subagent只同master agent通信,实现业务agent与网管系统的间接通信。实际工程结果表明:该方法对设计和开发综合业务网管系统切实可用,并能极大提高网管系统中管理设备和被管业务的动态扩展性。

With the standardization of network technologies and the continual growing of applications based on network, the research on network management are more and more focused on the management of service, and to study and design unified, integrated network management system become extraordinary important. The managed services application mainly receives query request from manager and send trap information to manager through agent which interacts with manager, in the real business platform there are a lot of services to be managed, so how to design a simple, low-cost, high expandable approach for agent extension is the key element to ensure the efficiency and reliability of NMS. Upon that, a design and implementation method for Multi-service agent extension in network management system based on Net-SNMP is presented in this paper： we use Net-SNMP serve as the master agent in a managed node, and embed the subagents into service applications, and the subagent only communicates with master agent to realize the indirect communication between service agent and manager. Practical engineering application result illustrates that the proposed method can work efficiently for the design and development of integrated service network manager, and it can greatly improve the dynamic expandability of the managed equipment and managed services.
