Abstract: A virtual network system for a computer network is provided. The system includes a first host executing a virtual network function manager. The system also includes a second host executing a management virtual machine. The management virtual machine is in communication with the virtual network function manager and with one or more virtual network function component instantiations. The management virtual machine is programmed to route messages between the one or more virtual network function component instantiations and the virtual network function manager.

Abstract: Expanding and contracting a display screen container. Data is stored in a computer readable medium. The data represents a screen container such as a graphical desktop user interface displayable to a user on a computer display of a computing device. Data is stored representing artifacts, including one or more application graphical user interface artifacts for applications that are instantiated on the computing device. Information is stored specifying locations where each of the artifacts should be graphically located in the screen container. The graphical size of screen container is determined by the locations of the artifacts. Based on user input, a portion of the screen container is displayed to the user on the computer display of the computing device. The screen container may be expanded or contracted based on opening or closing graphical user interface artifacts, adding or removing artifacts, or repositioning artifacts.
