Methods, systems, and computer-readable media for providing reliable switching between different transport protocols (e.g., TCP and UDP) are presented herein. In some embodiments, a computing platform may stop transmission over a transport protocol. Subsequently, the computing platform may synchronize buffers between a client and a host. For example, the buffer may include acknowledgments for undelivered reliable packets between the client and the host. Next, the computing platform may resume transmission over a different transport protocol. In some embodiments, when establishing an initial connection between a client and a host, connections may be attempted in parallel over multiple transport protocols. After a connection over a first transport protocol is established, if a connection is later established over a second transport protocol, the connection may be transitioned to the second transport protocol. Also, ticketing semantics may be preserved in the switch between the different transport protocols.

Adaptive session reliability over multiple transports

Methods, systems, computer-readable media, and apparatuses may provide virtualization of device management services (e.g., device drivers) dedicated managing a particular device and designed under for or under the assumption the particular device and the device management service will be utilized in a single session/user environment, so that virtual instances of the device management services may be used in a multi-session environment. Further, a redirection and/or virtualization layer may be created for each session in the multi-session environment to perform global database redirection, object name translation, and file system translation to ensure session boundaries are maintained and global/shared resources are not inappropriately altered by a session. As an example, the redirection/virtualization layer may redirect communications associated with a session and for a global resource to access a virtual instance of the resource specific to the session.

Virtualizing device management services on a multi-session platform

A method for maintaining a full-screen, integrated desktop environment on a remote machine for display to a user by a local machine includes monitoring, by a first agent on the remote machine, a desktop environment providing integrated access to a resource provided to a user of the local machine by the remote machine and a resource provided by the local machine to the user. The first agent generates a proxy window representing a window on the local machine displaying output data generated by the second resource and receives an identification of a change to the window on the local machine. The first agent modifies at least one data object in the desktop environment responsive to the change. The first agent transmits, to a second agent on the local machine, an identification of the modification. The second agent modifies attribute data associated with a data object displayed by the local machine.

Methods and systems for maintaining desktop environments providing integrated access to remote and local resources

The present invention is directed towards a method and system for accelerating delivery of a computing environment to a remote client. The computing environment may include a plurality of files comprising an application program and may be streamed to a remote client from a server. Responsive to a determination of whether transmission of the application may be accelerated, an appliance, intercepting the plurality of files, may accelerate transmission of the application program by applying one or more transport layer transmission acceleration techniques to the plurality of files.

Systems and methods for accelerating delivery of a computing environment to a remote user

The invention relates to methods and systems for reconnecting a client and providing user authentication across a reliable and persistent communication session. The method includes providing a first connection between a client and first protocol service and a second connection between the first protocol service and a host service. The first protocol service detects a disruption in the first connection. The client re-establishes the first connection between the client and the first protocol service while maintaining the second connection between the first protocol service and the host service. The first protocol service receives a ticket associated with the client and validates the ticket. The first protocol service links the re-established first connection to the maintained second connection after the ticket is validated.

Automatically reconnecting a client across reliable and persistent communication sessions

Systems and methods for remotely displaying three dimensional graphical data, include a local computing machine that communicates with a remote computing machine via a connection. An application executing on the local computing machine, generates three dimensional graphics commands which are intercepted and transferred to either the remote computing machine or a computing element on the local computing machine. Determining where to transfer the three dimensional graphics commands requires: an analysis of the application to obtain application specific characteristics; an analysis of the remote computing machine to obtain the capabilities of the remote computing machine; an analysis of the local computing machine to obtain the capabilities of the local computing machine; and an analysis of the connection to determine characteristics of the connection. A determination is made in response to obtaining the application characteristics, the remote computing machine capabilities, the local computing machine capabilities and the connection characteristics.

Methods and systems for remoting three dimensional graphical data

The invention relates to methods and systems for reconnecting a client and providing user authentication across a reliable and persistent communication session. A first protocol that encapsulates a plurality of secondary protocols is used to communicate over a network. A first protocol service, using the first protocol, provides session persistence and a reliable connection between a client and a host service. When there is a disruption in the network connection between a client and a host service when a client roams between networks, the connection is reestablished and the client's network connection is maintained thru a change in a network identifier assigned to the client.

Systems and methods for maintaining a client's network connection thru a change in network identifier

The invention relates to systems and methods for reestablishing client communications by securely traversing network components using an encapsulating communication protocol to provide session persistence and reliability. A first protocol that encapsulates a plurality of secondary protocols is used to communicate over a network to provide session persistence and a reliable connection between a client and a host service via a first protocol service. A ticket authority generates a first ticket and a second ticket associated with the client. The first ticket is provided to the client and the client uses the first ticket to establish a communication session with the first protocol service. The second ticket is provided to the first protocol service and the first protocol service uses the second ticket to establish a communication session with the host service.
