VoIP through OPNET s system in the loop (sitl). An extented guide for real time simulation of communication systems.

基于opnet的半实物仿真接口sitl介绍(An opnet semi-physical emulation interface sitl is introduced)

基于opnet系统级仿真平台的搭建方法，利用SITL模块实现半实物仿真(Based on the construction method of opnet system-level simulation platform, semi-physical simulation is realized by SITL module)
