Abstract

Systems and methods for transferring data among computing environments include a method for transferring data items among a portion of a remote computing environment and a portion of a local computing environment using a presentation layer protocol. Data items are transferred during transfer cycles and upon the release of data objects into a destination computing environment. Transfer cycles may transfer data among local and remote computing environments, among more than one remote computing environment, and may further transfer in parallel with other transfer cycles. A first transfer cycle transferring a first data item continues to transfer the first data item when a second transfer cycle initializes and transfers a second data item during a portion of the first transfer cycle. Data operations may be performed on data items during the transfer of a data item, and data items may be compressed or segmented prior to transfer.

Claims

1. A method for parallel transfer of a plurality of data items between a plurality of computing environments, the method comprising:

detecting, by a transfer agent executed by a processor of a first computing device, a release in a destination computing environment of a first graphical object, representing a first data item, dragged from a source computing environment;

transferring, during a first transfer cycle, initiated responsive to the detection of release of the first graphical object, the first data item from the source computing environment to the destination computing environment, wherein transferring the first data item comprises defining a location of a drop target in the destination computing environment and transferring the first data item to the defined drop target;

detecting, by the transfer agent, a release of a second graphical object, representing a second data item, dragged from one of the destination computing environment and the source computing environment to the other of the destination computing environment and the source computing environment; and

transferring, during a second transfer cycle initiated during execution of the first transfer cycle responsive to the detection of release of the second graphical object and during at least a portion of the first transfer cycle, the second data item correspondingly from one of the destination computing environment and the source computing environment to the other of the destination computing environment and the source computing environment.

2. The method of claim 1, wherein at least one of the source computing environment and the destination computing environment comprises a remote computing environment executed by a processor of a second computing device accessed via a remote access session.

3. The method of claim 2, wherein transferring the first data item from the source computing environment to the destination computing environment further comprises transferring the first data item via a virtual channel between the first computing device and a second computing device.

4. The method of claim 3, wherein transferring the second data item further comprises transferring the second data item via the virtual channel.

5. The method of claim 4, further comprising transferring packets of the first and second data items via the virtual channel in a round-robin allocation.

6. The method of claim 1, wherein the source computing environment comprises a first remote computing environment executed by a processor of a second computing device accessed via a first remote access session, and wherein the destination computing environment comprises a second remote computing environment executed by a processor of a third computing device accessed via a second remote access session.

7. The method of claim 6, wherein transferring the first data item from the source computing environment to the destination computing environment further comprises:

transferring the first data item from the source computing environment to a local computing environment executed by the first computing device; and

transferring the first data item from the local computing environment to the destination computing environment.

8. The method of claim 6, wherein transferring the first data item from the source computing environment to the destination computing environment further comprises transferring the first data item from the source computing environment via a virtual channel established between the second computing device and the third computing device.

9. A system for parallel transfer of a plurality of data items between a plurality of computing environments, the system comprising:

a first computing device, comprising a processor executing a transfer agent, the transfer agent configured for;

detecting a release in a destination computing environment of a first graphical object, representing a first data item, dragged from a source computing environment,

transferring, during a first transfer cycle, initiated responsive to the detection of release of the first graphical object, the first data item from the source computing environment to the destination computing environment, wherein transferring the first data item comprises defining a location of a drop target in the destination computing environment, and transferring the first data item to the defined drop target,

detecting a release of a second graphical object, representing a second data item, dragged from one of the destination computing environment and the source computing environment to the other of the destination computing environment and the source computing environment, and

transferring, during a second transfer cycle initiated during execution of the first transfer cycle responsive to the detection of release of the second graphical object and during at least a portion of the first transfer cycle, the second data item correspondingly from one of the destination computing environment and the source computing environment to the other of the destination computing environment and the source computing environment.

10. The system of claim 9, further comprising a second computing device comprising a processor executing a remote computing environment, the remote computing environment comprising one of the source computing environment and the destination computing environment, accessed by the first computing device via a remote access session.

11. The system of claim 10, wherein the transfer agent is further configured for transferring the first data item via a virtual channel between the first computing device and the second computing device.

12. The system of claim 11, wherein the transfer agent is further configured for transferring the second data item via the virtual channel.

13. The system of claim 12, wherein the transfer agent is further configured for transferring packets of the first and second data items via the virtual channel in a round-robin allocation.

14. The system of claim 9, further comprising:

a second computing device comprising a processor executing a first remote computing environment comprising the source computing environment, accessed by the first computing device via a first remote access session; and

a third computing device comprising a processor executing a second remote computing environment comprising the destination computing environment, accessed by the first computing device via a second remote access session.

15. The system of claim 14, wherein the transfer agent is further configured for:

transferring the first data item from the source computing environment to a local computing environment executed by the first computing device; and

transferring the first data item from the local computing environment to the destination computing environment.

16. The system of claim 14, wherein the transfer agent is further configured for transferring the first data item from the source computing environment via a virtual channel established between the second computing device and the third computing device.
