摘要： 在分析低轨(LEO)卫星网络的通信过程和几何特性的基础上，建立LEO卫星网络在全双工通信模式下的随机Petri网(SPN)模型，采用SPNP 6.0软件，针对2种安全协议IKE和ISAKMP的野蛮交换模式，以及空间通信协议规范SCPS-SP，分析卫星网络的平均时延并进行了模型仿真。

Abstract: On the basis of analyzing the communication process and geometric characteristics, this paper constructs a Stochastic Petri Net(SPN) model for Low Earth Orbit(LEO) satellite network under full duplex mode. Contraposing to two types of security protocols: IKE and ISAKMP’s aggressive mode and Space Communication Protocol Specification-Security Protocol(SCPS-SP), average time delay of satellite networks is analyzed and model-based simulation is conducted with Stochastic Petri Net Package(SPNP) 6.0.
