信息采集是网络管理的一项重要职能。然而,CORBA/SNMP网关的传统方法存在着能动性差等效率低下的弊端。针对这一问题,提出一种高效信息采集策略(EICP),详细阐述了其核心算法——预约竞争算法、截止期算法、自适应更新算法等。EICP通过动态地组织和管理被管对象信息树资源,根据统计意义上的访问频率进行自适应地更新和预读取,以截止期定界被管对象信息的有效性,来达到减少网络流量和缩短响应时间的目的。给出了相应的数学分析和仿真结果,从理论上对EICP的可行性和高效性予以验证。
Information collection is an important function of network management. However, the traditional method of CORBA / SNMP gateway has the drawbacks of low efficiency and poor efficiency. To solve this problem, this paper proposes a highly effective information collection strategy (EICP), elaborating its core algorithms - reservation competition algorithm, deadline algorithm, adaptive update algorithm and so on. EICP can adaptively update and pre-read the managed object’s information tree according to the access frequency in the statistical sense by dynamically organizing and managing the information tree of the managed object. In order to reduce the network traffic and improve the validity of the information of the managed object by the deadline, Shorten response time. The corresponding mathematical analysis and simulation results are given, and the feasibility and efficiency of EICP are verified theoretically.
