Abstract: A method for caching images in a virtual environment uses hash tables to store information about an application or window and to store updated images. Suitable areas of applications or windows are fixed relative to the window for many cases, and also include a relatively small number of possible display statuses. Hash tables are used on an agent side and a client side to track previous image updates. When an updated image is determined to be already stored in a cache, the agent side can transmit a hash identifying the image to the client side, and the client side can update the display with the cached image.

Abstract: A system is described for establishing a nested bridge to improve data exchange between a client device and a second virtual desktop that is accessed by the client device through a first virtual desktop in a nested mode configuration. The nested bridge can be established between a virtual desktop agent of the first virtual desktop and a virtual desktop client of the second virtual desktop, both of which can run in the first virtual desktop, to enable fast and efficient exchange of data between the agent and client within the first virtual desktop via a mechanism such as Inter-Process Communication (IPC). Consequently, the nested bridge can be utilized in conjunction with virtual channels connecting the client device to the first virtual desktop and virtual channels connecting the first virtual desktop to the second virtual desktop for exchanging data between the client device and the second virtual desktop via the first virtual desktop. As a result, a fast and efficient path for exchanging data between a client on the client device and the second virtual desktop is provided, which can be utilized for enabling and improving the performance of various features in the second virtual desktop.

Abstract: Disclosed are examples of embedding watermarks in a VDI session of a user. The watermark is based upon the user's identity and can be embedded into the VDI session to aid in the identification of data that is compromised from the VDI session. The watermark can be extracted from an image without needing the original image for extraction purposes.

Abstract: Techniques for implementing improved USB redirection of USB HID class devices are provided. In one set of embodiments a client system can receive, from a virtual desktop running on a server system, a poll message directed to an HID interface of a USB HID class device plugged into the client system and identify a polling thread associated with the HID interface. The client system can further save a copy of the poll message in the polling thread and initiate local polling of the HID interface, where the local polling comprises providing, via the polling thread, the copy of the poll message to the HID interface.

Abstract: The disclosure provides an approach for print redirection in a remote computing environment. Embodiments include receiving, on a remote device, a request to perform a printing task using a printing device associated with a client device. Embodiments include determining, on the remote device, that data associated with the request to perform the printing task exceeds a size threshold. Embodiments include generating, on the remote device, a plurality of data slices based on the data, wherein each respective data slice of the plurality of data slices comprises a respective subset of the data that does not exceed the size threshold. Embodiments include transmitting, from the remote device to the client device, the plurality of data slices as separate transmissions in separate time intervals along with information that allows the data to be reconstructed from the plurality of data slices for performing the printing task on the client device.

Abstract: Techniques are described for auditing clipboard operations in virtual desktop environments. The auditing takes place by detecting clipboard operations that are being redirected between the virtual desktop and the client device and recording log entries containing information about each clipboard operation that was redirected. In order to reduce auditing potential noise information, the redirection process is modified to delay populating the clipboard and recording log entries until a paste operation or other request for the clipboard is detected. In some situations, the clipboard redirection may be blocked based on the auditing capability, such as in cases where the auditing cannot take place due to the client computing device lacking support for auditing the clipboard operation and recording the necessary log entry.

Abstract: The disclosure herein describes a server-side system that dynamically enhances user experience on a remoting client device. During operation, the system monitors user inputs on the client device. When a user input involving a predetermined interaction between the user and the GUI on the client device is detected, the system alters parameters of frame encoding based on the user interaction. Frame updates transmitted to the client device during the user interaction are encoded with the altered encoding method to improve user experience. Once the user interaction is ended, the system reverts back to the normal encoding method.
