摘要： 针对卫星综合信息网中，卫星节点与地面站距离远、时延大、卫星节点动态性强的特点，建立卫星综合信息网中基于策略的网络管理的体系结构，提出在传统的策略决策点和策略执行点之间建立本地策略决策点的方法。该方法将本地策略决策点布置在具有管理功能的卫星代理上，实现局部策略决策点和策略执行点之间策略信息的交互，仿真结果表明该策略管理体系结构降低了网络管理的响应时延。

Abstract: In the integrated satellites information network, in terms of the characteristic that satellite network node is far from terrestrial station, the transmission delay is high and the mobility is intensive. Based on that characteristic, a new architecture is built for the network management architecture of the integrated satellites information network. The method that disposes a Local Policy Decision Point(LPDP) between the traditional Policy Decision Point(PDP) and Policy Enforcement Point(PEP) is proposed, and the LPDP can exchange the policy information with the PEP by disposing the LPDP on the satellite agent which has the function of management. The simulation results show that the new architecture can reduce the response delay of the network management.

Key words: integrated satellites information network, network management, Policy Based Network Management(PBNM) architecture, Local Policy Decision Point(LPDP)
