| 20080256389 | Strategies for Performing Testing in a Multi-User Environment - A strategy is described in which multiple testing agents perform multiple respective tests in a multi-user environment. One such multi-user environment allows multiple clients to interact with remote applications that are executed on a server. According to one exemplary case, a central test management module coordinates the execution of the multiple tests by the testing agents. For instance, the test management module can prevent testing agents that make demands on a global state of the multi-user environment from interfering with other testing agents. | 10-16-2008 |
| 20090187784 | FAIR AND DYNAMIC CENTRAL PROCESSING UNIT SCHEDULING - Embodiments that facilitate the fair and dynamic distribution of central processing unit (CPU) time are disclosed. In accordance with one embodiment, a method includes organizing one or more processes into one or more groups. The method further includes allocating a CPU time interval for each group. The allocation of a CPU time interval for each group is accomplished by equally distributing a CPU cycle based on the number of groups. The method also includes adjusting the allocated CPU time intervals based on a change in the quantity of the one or more groups. | 07-23-2009 |
| 20090204975 | PERFORMANCE INDICATOR FOR MEASURING RESPONSIVENESS OF USER INTERFACE APPLICATIONS TO USER INPUT - A method for measuring application responsiveness measures the time elapsed between receiving and processing a trailing tag message inserted into the application's message queue. The method receives a message, generates a trailing tag message associated with the message, and inserts the trailing tag message into the application's message queue. The trailing tag message includes a timestamp indicating when the trailing tag message was queued. A default message handler calculates the time elapsed between when the trailing tag message was queued and when the trailing tag message was processed. The elapsed time may then be used to calculated system responsiveness. | 08-13-2009 |
| 20090248885 | CONTROLLING THE TRANSFER OF TERMINAL SERVER DATA - The present invention extends to methods, systems, and computer program products for controlling the transfer of terminal server data. In some embodiments, contending request to send terminal server data are resolved by a flow control module situated between a terminal server protocol and a transport/network protocol. The flow control module utilizes channel priorities along with amounts of previously sent data per channel to determine how to distribute bandwidth in a relatively controlled manner between contending channels. The flow control module can be configured to intercept communication between terminal server protocol and a transport/network protocol to facilitate bandwidth distribution. In other embodiments, data is simultaneously sent over multiple channels of terminal server connection. A first write operation obtains a lock on a corresponding channel but the channel lock does not prevent write operations on other channels. | 10-01-2009 |
| 20100146127 | USER-MODE BASED REMOTE DESKTOP PROTOCOL (RDP) ENCODING ARCHITECTURE - Techniques are disclosed for a user-mode based remote desktop protocol (RDP) encoding architecture. A user mode desktop application and user mode virtual channel application run in user-mode session space. Virtual channel data from the virtual channel application is marshaled and sent to a RDP encoder process in user-mode system space. There it is converted to RDP protocol data units (PDU) and sent to a remote client across a communications network. Graphics data from the desktop application is sent to a display driver in kernel-mode session space and then to a graphics reflector that marshals the graphics data and sends it to the RDP encoder for a similar transformation. | 06-10-2010 |
| 20100161771 | INTERNET PROTOCOL (IP) ADDRESS VIRTUALIZATION FOR TERMINAL SERVER SESSIONS - Techniques are disclosed for virtualizing internet protocol (IP) addresses in terminal server sessions. A client component comprises a layer service provider (LSP) and a name service provider (NSP) that intercept a socket call to associate a port with a socket for a terminal server session. The client component queries a server component for a virtual IP address, and the server component determines whether the terminal server session can use a virtual IP address. Where the session can use a virtual IP address, the server returns a virtual IP address and the client component binds the socket call to the virtual IP address. Where the session cannot use a virtual IP address, the server returns an indication of that, and the client component acts as a proxy for that socket call and any future calls for that socket. | 06-24-2010 |
| 20110018883 | HYBRID REMOTE SESSIONS - High Fidelity remoting can be enabled by loading a hybrid remote session in a computer system. The hybrid remote session can include components loaded in a console session and components loaded in a remote session. | 01-27-2011 |
| 20110219112 | DETECTION OF END-TO-END TRANSPORT QUALITY - In various embodiments, methods and systems are disclosed for the real time detection of network conditions in conjunction with a remote presentation protocol. The link quality may represent the quality of the end-to-end connection between client and server with upper and lower bounds on the injection of additional traffic used for measurement. In some embodiments, the measurement technique may be selected based on the type of measurement that is desired. Accuracy may be maintained by selecting the type of measurement used based on current and previous network conditions. In one embodiment, a state model is used to determine the frequency of measurement and to determine when the measurements have produced a stable estimate of the link quality. | 09-08-2011 |
