Abstract

Claims (56)

1 . A method for handling events occurring in inactive or disconnected virtual desktop sessions, the method comprising:

establishing a remoting session between a virtual desktop client operating on a client device and a virtual desktop agent operating on a host server, the remoting session configured to access a virtual desktop running on the host server over a remote display protocol;

receiving, by the virtual desktop agent, configuration data identifying an application executing in the virtual desktop and one or more application events of the application to be monitored on the virtual desktop;

monitoring for occurrence of the one or more application events on the virtual desktop;

detecting an occurrence of the one or more application events on the virtual desktop;

determining whether the remoting session to access the virtual desktop is active or inactive;

in response to determining that the remoting session to access the virtual desktop is active, transmitting, via a virtual protocol channel of the remote display protocol, a notification to the virtual desktop client indicating that the one or more application events are occurring, wherein the virtual desktop client displays the notification; and

in response to determining that the remoting session is inactive,

maintaining, during inactivity of the remoting session, a first persistent connection between the virtual desktop agent and a connection server and a second persistent connection between the virtual desktop client and the connection server, independent of the remoting session;

sending, by the virtual desktop agent via the first persistent connection, a message to the connection server indicating occurrence of the one or more application events, wherein the connection server, in response to the message, instructs the client device via the second persistent connection to display a first option to reestablish the remoting session by the virtual desktop client and a second option to launch the application as a seamless window on the client device;

receiving an indication of a selection of the first option or the second option;

in response to receiving the indication of the selection of the first option, causing the remoting session to be reestablished between the virtual desktop agent and the virtual desktop client; and

in response to receiving the indication of the selection of the second option, causing the virtual desktop agent to launch the application on the virtual desktop and instructing the virtual desktop client to display the application executing on the virtual desktop as a seamless application window on the client device, wherein the seamless application window displays only a user interface of the application in which the one or more application events were detected and hides a remainder of a user interface of the virtual desktop that is executing the application.

2 . The method of claim 1 , wherein the one or more application events include an incoming communication in a videoconferencing application or instant messaging (IM) service.

3 . The method of claim 1 , wherein the connection server is configured to establish the remoting session between the virtual desktop client and the virtual desktop agent.

4 . The method of claim 1 , wherein during a time period while the remoting session is inactive, the virtual desktop client establishes a second remoting session to access a second virtual desktop.

5 . The method of claim 4 , wherein the notification is displayed on the client device while the virtual desktop client is accessing the second virtual desktop.

6 . A computing system, comprising:

at least one processor; and

memory including instructions that, when executed by the at least one processor, cause the computing system to perform the steps of:

establishing a remoting session between a virtual desktop client operating on a client device and a virtual desktop agent operating on a host server, the remoting session configured to access a virtual desktop running on the host server over a remote display protocol;

receiving, by the virtual desktop agent, configuration data identifying an application executing in the virtual desktop and one or more application events of the application to be monitored on the virtual desktop;

monitoring for occurrence of the one or more application events on the virtual desktop;

detecting an occurrence of the one or more application events on the virtual desktop;

determining whether the remoting session to access the virtual desktop is active or inactive;

in response to determining that the remoting session to access the virtual desktop is active, transmitting, via a virtual protocol channel of the remote display protocol, a notification to the virtual desktop client indicating that the one or more application events are occurring, wherein the virtual desktop client displays the notification; and

in response to determining that the remoting session is inactive,

maintaining, during inactivity of the remoting session, a first persistent connection between the virtual desktop agent and a connection server and a second persistent connection between the virtual desktop client and the connection server, independent of the remoting session;

sending, by the virtual desktop agent via the first persistent connection, a message to the connection server, wherein the connection server, in response to the message, instructs the client device via the second persistent connection to display a first option to reestablish the remoting session by the virtual desktop client and a second option to launch the application as a seamless window on the client device;

receiving an indication of a selection of the first option or the second option;

in response to receiving the indication of the selection of the first option, causing the remoting session to be reestablished between the virtual desktop agent and the virtual desktop client; and

in response to receiving the indication of the selection of the second option, causing the virtual desktop agent to launch the application on the virtual desktop and instructing the virtual desktop client to display the application executing on the virtual desktop as a seamless application window on the client device, wherein the seamless application window displays only a user interface of the application in which the one or more application events were detected and hides a remainder of a user interface of the virtual desktop that is executing the application.

7 . The computing system of claim 6 , wherein the one or more application events include an incoming communication in a videoconferencing application or instant messaging (IM) service.

8 . The computing system of claim 6 , wherein the connection server is configured to establish the remoting session between the virtual desktop client and the virtual desktop agent.

9 . The computing system of claim 6 , wherein during a time period while the remoting session is inactive, the virtual desktop client establishes a second remoting session to access a second virtual desktop.

10 . The computing system of claim 9 , wherein the notification is displayed on the client device while the virtual desktop client is accessing the second virtual desktop.

11 . A non-transitory computer readable storage medium comprising one or more sequences of instructions, the instructions when executed by one or more processors causing the one or more processors to execute the operations of:

establishing a remoting session between a virtual desktop client operating on a client device and a virtual desktop agent operating on a host server, the remoting session configured to access a virtual desktop running on the host server over a remote display protocol;

receiving, by the virtual desktop agent, configuration data identifying an application executing in the virtual desktop and one or more application events of the application to be monitored on the virtual desktop;
