The present disclosure provides systems and method for redirecting control of a client side connected USB device from the client to the server in a remote system. Specifically, the present disclosure creates a simulated USB device at the server. The simulated USB device is treated as a proxy for a redirected USB device at the client. The client side redirected USB device is not treated as the USB device but, rather, acts as a pass through to facilitate communication between requesting applications and the client connected device. The simulated USB device allows an application to send requests for a local device to the simulated USB device at the server. The simulated USB device then processes the requests and forwards the requests to the local device connected to the client.

USB device redirection for remote systems

Device redirection for remote systems

An invention is disclosed for conducting a remote presentation session with a client that uses a web browser to conduct the session. In embodiments, a proxy server exists between the remote presentation server and the client. The proxy server establishes a HTTP session with the client and a remote presentation session with the client. The server generates graphics encoded with a remote presentation protocol and sends them to the proxy, which re-encodes them as video and sends them to the client for display in the web browser. The client captures user input at the web browser and sends it to the proxy, which encodes it with the remote presentation protocol and sends it to the server to be processed.

Web-browser based desktop and application remoting solution

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.

Hybrid remote sessions

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.

Creating secure interactive connections with remote resources

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.

Plug and play device redirection for remote systems

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.

Sharing a port with multiple processes

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.

USB devices in application server environments

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.

Efficient encoding of alternative graphic sets

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.

Encoding for remoting graphics to decoder device

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.
