Abstract: Exemplary methods, apparatuses, and systems include a client virtual machine processing a system call for a device driver to instruct a physical device to perform a function and transmitting the system call to an appliance virtual machine to execute the system call. The client virtual machine determines, in response to the system call, that an established connection with the appliance virtual machine has switched from a first protocol to a second protocol, the first and second protocols including a high-performance transmission protocol and Transmission Control Protocol and Internet Protocol (TCP/IP). The client virtual machine transmits the system call to the appliance virtual machine according to the second protocol. For example, the established connection may switch to the second protocol in response to the client virtual machine migrating to the first host device from a second host device.

Abstract: Methods, systems, and computer programs are provided for managing remote display performance. One method includes operations for receiving notifications of events identified by an operating system, and for receiving notifications of display updates destined to a remote display coupled to a remote client. The method includes an operation for correlating events and display updates to determine the transmittal priority for the updates, where the priority is associated with a criticality for presenting the display updates on the remote display. Further, a subset of the display updates are identified as unnecessary for transmission to the remote client based, at least in part, on the priority of the display updates. Additionally, the method includes an operation for performing at least one of: discarding the subset; consolidating the subset into a single display update for transmittal to the remote client; or limiting the frequency of transmission of the subset to the remote client.

Abstract: Systems and techniques are described for modifying an executable file of an application and executing the application using the modified executable file. A described technique includes receiving, by a virtual machine, a request to perform an initial function of an application and an executable file for the application. The virtual machine modifies the executable file by redirecting the executable file to a custom runtime library that includes a custom function configured to initialize the application and to place the application in a paused state. A custom function call is added to the custom function in the executable file. The virtual machine initializes the application by executing the modified executable file, the executing causing the custom function to initialize the application and place the application in a paused state.

Abstract: Systems and methods described herein facilitate determining desktop readiness using interactive measures. A host is in communication with a server and the host includes a virtual desktop and a virtual desktop agent. The virtual desktop agent is configured to perform one or more injecting events via one or more monitoring agents, wherein each of the injecting events is a simulated input device event. The desktop agent is further configured to receive, via a display module, a response to the injecting event(s), wherein the response is a display update causing pixel color values for the display module to alter. The desktop agent is also configured to identify, via the monitoring agent(s), whether the response to the injecting event(s) is an expected response. The desktop agent is also configured to determine, via the monitoring agent(s), a readiness of the virtual desktop based on the expected response.

Abstract: Methods, systems, and computer programs are provided for measuring the performance of display images received on a remote computer display. One method includes an operation for detecting calls from an application to an application programming interface (API), which is provided for rendering images on a display image, each call causing an update of the display image. Further, the method includes an operation for embedding data for measuring performance in display frames of the display image based on the detecting. The embedding results in modified displayed frames with respective data for measuring performance. The modified displayed frames are transmitted to a remote client, which results in received modified display frames having respective received data for measuring the performance. In addition, the method includes an operation for calculating the remote display quality for the given application based on the received modified display frames and the respective received data for measuring performance.

Abstract: In one embodiment, a method displays images from a remote desktop of a desktop GUI on a client device. The method receives a plurality of image blocks for a frame update of an image of the desktop GUI being displayed on the client device. The remote desktop is being run on a host. The client device determines that one or more missing image blocks have not been received for the frame update and determines if the frame update should be performed without the one or more missing image blocks. If the frame update of the desktop GUI should be performed without the one or more missing image blocks, the client device performs the frame update of the desktop GUI using the plurality of image blocks without using the one or more missing image blocks.

Abstract: The disclosure herein describes a client-side system that enhances user experience on a remoting client without consuming additional network bandwidth. During operation, the system receives a sequence of frame updates for a display screen, and determines a sequence of frames corresponding to the frame updates. The system further adaptively applies one or more image enhancing techniques to the sequence of frames based on available network bandwidth, frame refresh rate, or image quality. The image enhancement techniques include predicting a frame based on previously received frames, interpolating a frame based on at least two buffered frames, and reducing appearance of artifacts in a received frame, thereby reducing visual artifacts.
