摘　　要：通过分析现有HLA/RTI仿真系统由局域网扩展到广域网所遇到的问题,利用虚拟专用网隧道技术构建了仿真虚拟专用网(SVPN,Simulation Virtual Private Network)环境,提出并实现了一种"轻量级"的广域网环境下分布仿真实现方法。针对广域网上进行分布式仿真对安全和多播应用需求,给出了基于IPSec协议的解决方案,并讨论具体技术实现方法,设计了仿真数据的封装形式,并给出了SVPN在不同工作模式下的信息流程。最后在一个仿真场景中,对SVPN软件的功能和性能进行了实验分析。Some problems of extending to WAN in legacy LAN distributed simulation system were analyzed.An SVPN（Simulation Virtual Private Network） infrastructure was proposed based on tunnel technology,which is a lightweight method to realize distributed simulation over WAN.To meet the needs of security and multicast translation in WAN environment,the SVPN system provided a solution based on IPSec protocol.A discussion on the simulation data encapsulation and different information processes in various application cases was detailed.Finally,the research result was applied in a distributed simulation system,which shows that the solution provides satisfied functions and works effectively.
