摘要
面向行为复杂与协议多样的天地一体化信息网络用户行为仿真需求,设计一种基于云计算与虚拟化技术的天地一体化信息网络用户行为流量回放架构。进一步研究基于深度报文解析的用户行为流量自动解析与模板生成技术,以及基于流量模板的天地一体化信息网络用户行为流量回放技术,实现各类用户行为流量的统一、自动化和逼真仿真。构建具有6颗天基骨干网卫星、66颗天基接入网卫星的天地一体化信息网络仿真场景,宽带用户行为与窄带用户行为协议流量模板生成与流量回放实验验证表明,该方法能够实现多样化的用户交互行为的仿真,可为天地一体化信息网络仿真提供有效支撑。
Faced the needs of user behavior emulation of the space-integrated-ground information network with complex behaviors and diverse protocols,an architecture based on cloud computing and virtualization technologies for replaying user behavior traffic in the spaceintegrated-ground information network was designed.Furthermore,a user behavior traffic automatic analysis and traffic profile generation technology based on deep packet inspection, and a user behavior traffic replay technology of the space-integrated-ground information network based on traffic profile were researched, to achieve unified,automated,and realistic simulation of miscellaneous kinds of user behavior traffic.An emulation scenario of a space-integrated-ground information network with 6 space-based backbone network satellites and 66 space-based access network satellites was constructed.The experimental verification of protocol traffic profile traffic replay of the broadband user behavior and narrow-band user behavior showed that the emulation of diversified user interaction behaviors could provide effective support for the emulation of the space-integrated-ground information network.
