Real-time screen-sharing provides users with ubiquitous access to remote applications, such as computer games, movie players, and desktop applications (apps), anywhere and anytime. In this article, we study the performance of different screen-sharing technologies, which can be classified into native and clientless ones. The native ones dictate that users install special-purpose software, while the clientless ones directly run in web browsers. In particular, we conduct extensive experiments in three steps. First, we identify a suite of the most representative native and clientless screen-sharing technologies. Second, we propose a systematic measurement methodology for comparing screen-sharing technologies under diverse and dynamic network conditions using different performance metrics. Last, we conduct extensive experiments and perform in-depth analysis to quantify the performance gap between clientless and native screen-sharing technologies. We found that our WebRTC-based implementation achieves the best overall performance. More precisely, it consumes a maximum of 3 Mbps bandwidth while reaching a high decoding ratio and delivering good video quality. Moreover, it leads to a steadily high decoding ratio and video quality under dynamic network conditions. By presenting the very first rigorous comparisons of the native and clientless screen-sharing technologies, this article will stimulate more exciting studies on the emerging clientless screen-sharing technologies.

原生与无客户端实时屏幕共享技术的性能比较

实时屏幕共享使用户可以随时随地访问远程应用程序,例如计算机游戏、电影播放器​​和桌面应用程序(应用程序)。在本文中,我们研究了不同屏幕共享技术的性能,这些技术可以分为原生和无客户端。原生软件要求用户安装专用软件,而无客户端软件则直接在 Web 浏览器中运行。特别是,我们分三个步骤进行了广泛的实验。首先,我们确定了一套最具代表性的原生和无客户端屏幕共享技术。其次,我们提出了一种系统的测量方法,用于使用不同的性能指标在不同和动态的网络条件下比较屏幕共享技术。最后的,我们进行了广泛的实验并进行了深入的分析,以量化无客户端和原生屏幕共享技术之间的性能差距。我们发现我们基于 WebRTC 的实现实现了最佳的整体性能。更准确地说,它消耗最大 3 Mbps 带宽,同时达到高解码率并提供良好的视频质量。此外,它还可以在动态网络条件下实现稳定的高解码率和视频质量。通过首次对原生和无客户端屏幕共享技术进行严格比较,本文将激发对新兴无客户端屏幕共享技术的更多令人兴奋的研究。我们发现我们基于 WebRTC 的实现实现了最佳的整体性能。更准确地说,它消耗最大 3 Mbps 带宽,同时达到高解码率并提供良好的视频质量。此外,它还可以在动态网络条件下实现稳定的高解码率和视频质量。通过首次对原生和无客户端屏幕共享技术进行严格比较,本文将激发对新兴无客户端屏幕共享技术的更多令人兴奋的研究。我们发现我们基于 WebRTC 的实现实现了最佳的整体性能。更准确地说,它消耗最大 3 Mbps 带宽,同时达到高解码率并提供良好的视频质量。此外,它还可以在动态网络条件下实现稳定的高解码率和视频质量。通过首次对原生和无客户端屏幕共享技术进行严格比较,本文将激发对新兴无客户端屏幕共享技术的更多令人兴奋的研究。
