【摘要】：随着经济的发展,远程视频监控系统在当今社会起到了越来越重要的作用,视频监控传输协议的研究也越来越受到人们的重视。当前物流监控平台中视频发布系统多采用了C/S模式,这样运营方需要支付高昂的宽带费用,很大程度上限制了视频监控在物流领域的应用。传统的P2P技术虽然能够帮助减少服务端的带宽开支,但是需要开发特定的客户端,跨平台性较差,不能随时查看监控信息。而基于FLASH平台的P2P视频传输不仅极大的降低了服务器端的带宽消耗,并且无需开发专门的客户端,所有支持Flash的浏览器即可运行视频监控播放器。因此将Flash P2P技术应用于视频监控领域变得十分重要。本文从协议数据格式、协议交互流程、协议的应用、流量特征以及流量本地化等方面对RTMFP协议进行了详细、深入的研究分析,并针对当前Flash P2P技术在实际应用中存在的不足,提出了基于Openflow的Flash P2P流量优化方案,该方案经仿真验证,有效的解决了Flash P2P在应用中存在的流量本地化不理想、Qos低的问题。最终,设计实现了Flash P2P视频监控与分析系统,该系统中RTMFP协议分析模块对Flash P2P流量进行识别、统计分析,实时显示当前网络中Flash P2P的流量变化规律以及本地化情况。同时,基于RTMFP协议的视频监控模块,成功的解决了传统远程视频监控高带宽消耗而且不可跨平台的不足。
[Abstract]:With the development of economy, remote video surveillance system plays a more and more important role in today's society, and more people pay attention to the research of video surveillance transmission protocol. At present, most of the video distribution systems in the logistics monitoring platform use C / S mode, so the operators have to pay high broadband fees, which limits the application of video surveillance in the field of logistics to a large extent. Although the traditional P2P technology can help to reduce the bandwidth expense of the server, it needs to develop specific clients, so the cross-platform is poor, and the monitoring information can not be viewed at any time. P2P video transmission based on FLASH platform not only greatly reduces the bandwidth consumption of the server, but also does not need to develop a special client, all the browsers that support Flash can run the video monitor player. So it is very important to apply Flash P2P technology to video surveillance. In this paper, the RTMFP protocol is studied and analyzed in detail from the aspects of protocol data format, protocol interaction flow, protocol application, traffic characteristics and traffic localization, and the deficiency of current Flash P2P technology in practical application is analyzed. A Flash P2P traffic optimization scheme based on Openflow is proposed. The scheme is verified by simulation, which effectively solves the problem of Flash P2P traffic localization is not ideal and Qos is low. Finally, the Flash P2P video surveillance and analysis system is designed and implemented. In this system, the RTMFP protocol analysis module is used to identify and analyze the P2P traffic of Flash, and to display the change rule and localization of P2P traffic in the current network in real time. At the same time, the video monitoring module based on RTMFP protocol successfully solves the high bandwidth consumption and non-cross-platform deficiency of traditional remote video surveillance.
