YouTube作为世界最大的视频网站,在网络流量中的占比日益增加。大量的视频流量给互联网服务提供商带来了巨大的挑战。随着YouTube全站采用HTTPS加密,如何从HTTPS加密流量中获取视频QoE评估信息至关重要。在分析了YouTube App在Android和IOS平台上所采用的流媒体传输模式的基础上,提出了C4.5决策树与[K]-means聚类相结合的方法对视频片段进行分辨率识别。实验结果证明该方法能够准确地识别视频播放过程中每个视频片段的播放码率及分辨率。 相似文献

Classical approaches for remote visualization and collaboration used in Computer-Aided Design and Engineering (CAD/E) applications are no longer appropriate due to the increasing amount of data generated, especially using standard networks. We introduce a lightweight and computing platform for scientific simulation, collaboration in engineering, 3D visualization and big data management. This ICT based platform provides scientists an “easy-to-integrate” generic tool, thus enabling worldwide collaboration and remote processing for any kind of data. The service-oriented architecture is based on the cloud computing paradigm and relies on standard internet technologies to be efficient on a large panel of networks and clients. In this paper, we discuss the need of innovations in (i) pre and post processing visualization services, (ii) 3D large scientific data set scalable compression and transmission methods, (iii) collaborative virtual environments, and (iv) collaboration in multi-domains of CAD/E. We propose our open platform for collaborative simulation and scientific big data analysis. This platform is now available as an open project with all core components licensed under LGPL V2.1. We provide two examples of usage of the platform in CAD/E for sustainability engineering from one academic application and one industrial case study. Firstly, we consider chemical process engineering showing the development of a domain specific service. With the rise of global warming issues and with growing importance granted to sustainable development, chemical process engineering has turned to think more and more environmentally. Indeed, the chemical engineer has now taken into account not only the engineering and economic criteria of the process, but also its environmental and social performances. Secondly, an example of natural hazards management illustrates the efficiency of our approach for remote collaboration that involves big data exchange and analysis between distant locations. Finally we underline the platform benefits and we open our platform through next activities in innovation techniques and inventive design. 相似文献

叙述了一个基于校园网、来自于多个管理信息系统的综合信息网上查询软件系统的设计实现过程及相关技术。系统的特点在于在不改动原有管理信息系统软件的前提下,能够把分布在不同部门、不同软硬件环境下的数据进行整合,以统一的形式呈现给查询者。对于许多国内高等院校而言,这一特点很适合当前校园网相关软件系统建设的需要。通过对该系统实现过程的研究,可以为从事相关工作的读者提供一些借鉴。 相似文献
