摘要： A Virtual Access Core (VAC) manages and controls access to virtual machines. A Virtual Instruction Routine (VIR) protocol is used by all components of the system to pass instructions and information about a Virtual Session. The VAC issues commands in the VIR protocol language causing virtual machines to start and stop. A VIR host that hosts virtual machines responds to VAC commands. Web clients access the system via links, which a web server uses to send access requests to the VAC. The VAC responds by searching through process memory and database tables for information about free slots on a plurality of VIR hosts grouped into a Host Array. When one or more free slots have been identified, the VAC issues VIR Protocol commands instructing one or more VIR Hosts to load and start specific virtual machines in Specific Slots. Each VIR Host looks up a set of firewall rules dynamically created, with instructions on how to isolate and create a Virtual Network for that client session providing privacy and non-interference between virtual machines in the Host Array. The VAC passes instructions to a VNC Proxy enabling communication between the client session and the virtual machine. An example of use of the system is a Virtual Classroom where students are given access to a Virtual Network enabling them to perform practical exercises as an augmentation to their web based training.
摘要翻译：虚拟访问核心（VAC）管理和控制对虚拟机的访问。系统的所有组件都使用虚拟指令例程（VIR）协议传递关于虚拟会话的指令和信息。 VAC以VIR协议语言发出命令，导致虚拟机启动和停止。托管虚拟机的VIR主机响应VAC命令。 Web客户端通过链接访问系统，网络服务器用于向VAC发送访问请求。 VAC通过搜索进程内存和数据库表来响应分组到主机阵列的多个VIR主机上的空闲时隙的信息。当识别出一个或多个空闲插槽时，VAC发出VIR协议命令，指示一个或多个VIR主机加载并启动特定插槽中的特定虚拟机。每个VIR主机都会查找一组动态创建的防火墙规则，并提供有关如何隔离并为该客户端会话创建虚拟网络的说明，从而提供主机阵列中的虚拟机之间的隐私和不受干扰。 VAC将指令传递给VNC代理，从而实现客户端会话和虚拟机之间的通信。使用该系统的一个例子是虚拟课堂，学生可以访问虚拟网络，使他们能够进行实践练习，作为其基于网络的培训的扩充。
