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

Techniques for centralized publishing of network resources within computer networks are described. Publication of and access to the network resources are controlled from a single, centralized location, advantageously improving the uniformity of network administration responsibilities, and overall robustness of the network.

Centralized publishing of network resources

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 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.

Remote protocol support for communication of large objects in arbitrary format

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.

A system and method for managing and enforcing software licenses through automating per-seat software licensing using a 'leased license' approach provides vendors with the assurance that purchasers are complying with software licenses while maximizing a customer's use of purchased software licenses. Licenses are automatically enforced by expiring leased licenses and making the expired licenses available again for use by client computers. A system includes a licensing clearinghouse, a license server, clients, and terminal servers. A terminal server assists a client in obtaining a license with an expiration date from a license server, and helps maintain the client's license status through license requests to the license server. Licenses that expire are recycled and made available again to clients. Prior to expiring, licenses are automatically updated during a license update period, and if a license is lost, a temporary license is issued. After the license update period, clients may receive a license update or a new license. Temporary licenses are replaced with permanent licenses that are returned to the available license pool, thus netting out the overall distribution of purchased licenses and assuring that a customer's use of purchased licenses in not lost.

Upon successfully authenticating a client device with a server system, the client device and server system share auto-reconnect data. Upon subsequently losing and re-establishing communications with the server system, the client sends an auto-authenticate request to the server. The auto-authenticate request includes a session verifier that is based at least in part on the shared auto-reconnect data. The server validates the session verifier. If the validation is successful, the server automatically re-authenticates the client device.

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. The terminal client retrieves the information in the fragment cache entry and then retrieves the glyph data for the glyphs of the fragment from the glyph cache, and displays them on the remote terminal.

A server operating system supports multiple client-server sessions and enables a user to begin a session and later dynamically reconnect to that session even if the user uses two different client computers. The operating system has a multi-user session manager to enable multiple client-server sessions on the server and a multi-user stack protocol manager to manage one or more protocol stacks used in communicating with the clients. When a user connects to the server via a first client, the stack protocol manager assigns a first protocol stack to this first client-server connection and the session manager creates a first session for the user. When the user subsequently reconnects to the server using a second client that is different from the first client, the stack manager assigns a second protocol stack to a second client-server connection and the session begins creating a second session for the user. During this latter process, however, the session manager recognizes that the user is affiliated with the first session. The session manager adapts the first session to conform to the system configuration of the second client. The session manager then reassociates the second protocol stack with the reconfigured first session so that the user is returned to his/her original session, even though they logged on from a different client.
