如何提高LTE网络中移动的视频流的端到端服务可靠性的研究正在蓬勃发展，仿真是评估这一研究的最佳手段。然而，据我们所知，所有现有的LTE网络模拟器都提供相对封闭的虚拟网络的模拟，其中只能模拟无意义的跟踪数据被传递。对移动的视频流的研究还没有得到充分的支持。有鉴于此，在此，开放式LTE模拟器Open-Sim被制成提供虚拟LTE网络的模拟，该虚拟LTE网络具有通过真实的有线链路实时连接实际主机的能力。视频流的传输和应用层相关逻辑可以部署在远程主机上，不再受模拟器框架的限制。因此，Open-LTE与关于移动的视频流的大多数方面的实验研究兼容。Open-LTE通过提供集中式配置文件来设置LTE信道衰落场景并将真实的流量与虚拟LTE网络互连，因此使用简单。我们将展示我们的工作与实时视频流应用程序上的QoE实验。
Simulation is the optimal means to evaluate the booming researches on how to enhance the end-to-end service reliability of mobile video streaming over LTE network. However, to the best of our knowledge, all existing LTE network simulators provide simulations of relatively closed virtual networks, in which only meaningless tracing data can be simulated being delivered. Researches on mobile video streaming have not yet been fully supported. In light of this, herein, the open LTE simulator Open-Sim is made to provide the simulation of virtual LTE network with the ability to connect actual hosts over real wired link in realtime. The transport and application layer related logics of video streaming can be deployed on remote hosts and will no longer be limited by the simulator framework. Open-LTE is thus compatible with experimental studies on most aspects of mobile video streaming. Open-LTE is simple to use by providing a centralized configuration file to set up the LTE channel fading scenarios and interconnect real traffic with the virtual LTE network. We will demonstrate our work with QoE experiments on a live video streaming application.
