Abstract: Space information network is an intelligent system constituted by information systems of land, sea, air and space. An algorithm of management domain division was proposed to meet the needs of scalability in network management for space information network. An organization model of management was designed. Analytic Hierarchy Process (AHP) was used to select sub-management station, and then appropriate management domains could be formed. In domain maintenance phase, the function of sub-management station was migrated by mobile Agents. Dynamical maintaining mechanisms like domain merger/partition, reaffiliation and adaptive adjustment of information update period were also designed. The overhead and time spent in division as well as in data collecting for management were analyzed through simulations. The experimental results show the proposed algorithm of management domain division is suitable for space information network.

摘要： 空间信息网是一种由陆海空天信息系统构成的智能化网络，针对空间信息网网络管理可扩展性方面的要求，提出一种管理域划分算法。建立基于动态分层结构的网络管理组织模型，使用层次分析法(AHP)选举管理分站，规划合理的管理区域；采用移动代理技术迁移管理分站的功能进行管理域维护，并提出包括管理域合并、分裂、切换的维护机制。仿真实验对管理域划分开销、划分时间和管理数据采集时间进行了分析，结果表明算法能有效执行空间信息网管理区域的划分。
