Abstract: A remote access system connects a server computer with one or more client computers, where devices are connected locally at the client computers. The devices are recognized by the client computers and a device driver is provided for each connected and recognized device. A virtual driver is created at the server computer from information specific to the device, such that the virtual driver acts as an actual driver to an application on the server computer. The application through the virtual driver is able to recognize and provide commands to the connected device.

Abstract: 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.

Abstract: A server computer hosts one or more application programs that are accessed by a client computer. Higher-level graphics commands describing graphics images are received from the application programs. The server computer determines whether the client computer is able to generate graphics using the higher-level graphics commands or generates graphics using relatively lower-level graphics commands. The server computer sends higher-level or relatively lower-level graphics commands depending on whether the client computer generates graphics using higher-level or relatively lower-level graphics commands.

Abstract: Implementations of the present invention relate to a communication framework that is readily adaptable to a wide variety of resources intended to be accessible through a firewall. In general, a communication framework at a gateway server can provide a specific connection to a requested resource in accordance with a wide range of resource and/or network access policies. In one instance, a client requests a connection to a specific resource behind a firewall. The communication framework authenticates the connection, and quarantines the connection until determining, for example, that the client is using an appropriate resource features. If appropriately authenticated, the communication framework can pass control of the connection to an appropriately identified protocol plug-in processor, which facilitates a direct connection to the requested resource at an application layer of a communication stack.

Abstract: A server computer provides objects such as bitmaps representing graphics image for processing by a client computer or device. The object may be of any arbitrary size or format, and is converted to a data structure that can be received by the client computer. Synchronized metadata may be included in the data structure, where such metadata data is used by an application in the client computer or device.

Abstract: Techniques relating to managing multimedia transmissions in terminal services scenarios are described. In one instance, a method sends a user-interface component from a server to a remote client. The method further streams a media component for presentation on the remote client in combination with the user-interface component and wherein the media presentation is tracked but not displayed by the server.

Abstract: A method and system of operating a remote terminal by a terminal server caches representation data of glyphs to be displayed on the remote terminal to reduce the amount of glyph data that have to be transmitted to the remote terminal through a network connection. The glyph caching is performed on a level of text fragments each of which includes a plurality of glyphs. The remote terminal stores a fragment cache for caching fragments and glyph caches for caching individual glyphs. Each entry in the fragment cache contains data indicating where the glyph data for the glyphs of the fragment are stored in the glyph caches. When the terminal server receives a request to display a text fragment on the remote terminal, it checks whether that fragment is cached at the remote terminal. If so, the terminal server sends a fragment index to the client identifying the entry in the fragment cache for that fragment.

Abstract: A portable graphics encoder connects with one or more protocol decoder devices based on a particular communication protocol. The portable graphics encoder is not specific to any particular operating system. The portable graphics encoder receives protocol decoder device commands such as input instructions that determine higher-level graphics commands that are sent to the one or more protocol decoder devices. The higher-level graphics commands are extracted from graphics sources such as application programs. The portable graphics encoder encodes the higher-level graphics commands according to a format defined by the communication protocol, and the encoded higher-level graphics commands are sent to the one or more protocol decoder devices.

Abstract: The present invention is directed to appropriately rendering terminal server graphical data at multiple client side monitors. In some embodiments, a client sends client side monitor configuration for a plurality of monitors to a server. The server simulates a virtual desktop for the plurality of monitors based on the client side monitor configuration. Graphical data generated for the simulated virtual desktop is converted to drawing commands and returned to the client for rendering. In other embodiments, a separate terminal server session is established for each of a plurality client side monitors. Drawing commands for a specified client side monitor is sent from the terminal server to the client over the corresponding session for the client side monitor.

Abstract: Embodiments provide for efficient encoding and rendering of remote graphic displays by applying one or more of the following: (1) field encoding for identifying fields of a graphics set such that commonalities of various fields across different graphics languages are identified; (2) resource caching, which treats heterogeneous resources in a homogeneous way when it comes to storing them; (3) determining the type of encoding for remoting items within a graphics set based upon the types of compression mechanisms supported by a remote device; (4) improving responsiveness by rendering with partially sent resources; (5) a mechanism for determining what portions (if any) of a graphics set should be sent to a remote device and in what order; and (6) use of dedicated resources already on a remote device in order to eliminate the transfer of a resource between a local device and the remote device when rendering such resource.

Abstract: Implementations of the present invention efficiently establish secure connections between a client and server, at least in part by authenticating the client and server early on in the connection setup phases. A client initiating a connection with a server identifies the secure communication protocols enabled at the client, and identifies these protocols in a connection request it sends to the server. The server processes the message and responds with a communication protocol it deems appropriate for the connection. The client and server then exchange appropriate authentication information, and then establish a connection session that implements the chosen communication protocol, and encrypts messages using the negotiated communication protocol. Additional implementations relate to reestablishing dropped connections behind virtual Internet Protocol addresses, without necessarily having to recommit much connection resource overhead.

Abstract: A port listening service operating in at system level is assigned to listen on a static port. The static port can index a plurality of unique IDs associated with a plurality of applications operating in a session level. The server application can then provide to a client the unique connection ID, the IP address of the server, and the static port number for a connection. If the client connects by referencing the unique connection ID, the port listening service can forward a corresponding socket for the connection to the appropriate application instance, such that the application still operates in a session level. As such, the port listening service can dispatch connection services for a single static port to multiple different application instances running in a session level.

The micro core may be extended to include additional features or service as needed by the client device.

Abstract: One or more universal serial bus (USB) devices are connected at a client computer. The USB devices are recognized by the client computer and a determination is made as to whether an application server computer provides functionality for one or more of the USB devices. A specific communication path is provided from the USB device to the server computer if functionality is provided by the application server computer.
