基于网络通信引擎ICE架构的云桌面录屏方法及装置
交叉引用
本申请引用于2018年12月26日递交的名称为“基于网络通信引擎ICE架构的云桌面录屏方法及装置”的第201811603809.8号中国专利申请，其通过引用被全部并入本申请。
技术领域
本申请涉及云桌面技术领域，尤其涉及一种基于网络通信引擎ICE架构的云桌面录屏方法及装置。
背景技术
随着互联网技术及云计算的快速发展，云桌面技术日趋成熟，云桌面的投入使用，降低了企业的IT成本投入，而且增强了系统的可维护性和安全性，绿色环保。随着云桌面的广泛部署，尤其是涉密企业，安全性也越来越受到重视。为了安全审计，需要对云桌面进行录屏监控。
目前，现有的对云桌面进行录屏监控，一般采用的是spice架构的云桌面录屏方法，例如，包括客户端、代理服务器和安装在虚拟机上的服务器，用户通过浏览器客户端访问虚拟机，代理服务器接收来自浏览器的虚拟机访问请求，代理服务器初始化虚拟机访问信息并对客户端带过来的认证信息转发到虚拟机上的服务器，虚拟机上的服务器对访问进行安全认证，同时，代理服务器启动录屏的线程对虚拟机的界面进行录屏，并生成录屏文件保存到代理服务器上。
采用这种架构的录屏方法，很好的解决了录屏行为在终端设备上进行，所存在的终端用户为了逃避审计，而终止终端设备上的录屏程序，以及将桌面的数据全部保留下来，所产生的大量数据冗余，对服务器产生较大压力的问题。
然而，由于采用这种spice架构的云桌面录屏方法，当企业出于安全方面的考虑，需要采用网路隔离时，就会造成上述代理服务器与虚拟机无法进行数据传输，最终导致代理服务器启动录屏线程无法对虚拟机的界面进行录屏操作。
由此可知，当存在网络隔离的情况时，采用现有的spice架构的云桌面录屏方法，将无法实现对云桌面进行录屏监控。
