Abstract

A computer implemented method for performing automatic latency mitigation in a remote access system comprises using a network connection between a client in remote access with a server to define a virtual channel for determining latency in the network connection, and providing a latency value for the connection. The latency value is used to determine a mitigating action for reducing the latency or the effect of latency in the connection, and the mitigating action is executed at the client.

Claims

1. A computer implemented method for performing automatic latency mitigation in a remote access system, comprising:

using a network connection between a client in remote access with a server to define a virtual channel for determining latency in the network connection, and providing a latency value for the connection;

compiling a limited running list of historic latency values, and using the list to determine an average value for the latency between the client and server;

providing multiple threshold values representing respective different connection statuses;

assigning a status for the connection using the average value;

incrementing or decrementing a counter associated with the statuses based on the assigned status to provide a current status for the connection;

using the latency value to determine a mitigating action relating to the latency in the connection; and

executing the mitigating action at the client.

2. A computer implemented method as claimed in claim 1, wherein the mitigating action serves to reduce the latency in the connection.

3. A computer implemented method as claimed in claim 1, wherein the mitigating action serves to reduce an effect on a user of the latency in the connection.

4. A computer implemented method as claimed in claim 1, wherein the virtual channel is used to transmit data representing the latency value between the client and the server using the network connection.

5. A computer implemented method as claimed in claim 1, further comprising

providing a profile list including multiple display parameters for a display device of the client, wherein respective ones of the parameters map to respective ones of the connection statuses.

6. A computer implemented method as claimed in claim 5, further comprising

adjusting a parameter of the display device on the basis of the current status and according to the profile list.

7. A computer implemented method as claimed in claim 1,

wherein multiple display parameters for a display device include a resolution and colour depth.

8. A computer implemented method as claimed in claim 1, further comprising:

providing a profile list including multiple audio parameters for an audio device of the client,

wherein respective ones of the parameters map to respective ones of the connection statuses.

9. A computer implemented method as claimed in claim 1, further comprising:

providing a profile list including multiple audio parameters for an audio device of the client; and

adjusting a parameter of the audio device on the basis of the current status and according to the profile list,

wherein respective ones of the parameters map to respective ones of the connection statuses.

10. A computer implemented method as claimed in claim 1, wherein the latency value is determined using a difference between a timestamp in a message received by the server from the client and a current timestamp value of the server.

11. A computer implemented method as claimed in claim 1, wherein the network connection is a TCP connection.

12. A server comprising a server component to receive data from a client over a virtual channel representing a value for the latency in a physical connection for remote access therebetween, wherein

the server component is operable to compile a limited running list of historic latency values, and

to use the list to determine an average value of latency between the client device and server device, and

to provide multiple threshold values representing respective different connection statuses, to assign a status for the connection using the average value, to increment or decrement a counter associated with the statuses based on the assigned status to provide a current status for the connection, and

to provide a profile list including multiple display parameters for a display device of the client device, wherein respective ones of the parameters map to respective ones of the connection statuses,

to use the latency value to determine a mitigating action relating to the latency in the connection, and to send instruction data to such a client in order to execute the mitigating action at the client.

13. A server as claimed in claim 12, wherein the mitigating action serves to reduce the latency in the connection.

14. A server as claimed in claim 12, wherein the mitigating action serves to reduce an effect on a user of the latency in the connection.

15. A server as claimed in claim 12, wherein the server component is operable to use the virtual channel to transmit data representing the latency value between the client device and the server device, to the client device using the network connection.

16. A server as claimed in claim 12, wherein the server component is further operable to adjust a parameter of the display device on the basis of the current status and according to the profile list, wherein respective ones of the parameters map to respective ones of the connection statuses.

17. A server as claimed in claim 12, wherein the multiple display parameters include a resolution and colour depth for the display device.

18. A server as claimed in claim 12, wherein the server component is operable to send data to the client device over the virtual channel, the data representing a time period between a timestamp in a message received by the server device from the client device and a current timestamp value of the server device.

19. A server as claimed in claim 12, and further comprising a client component operable to receive data from the server device over a virtual channel, the data representing a mitigating action relating to latency in a network connection between the server device and the client device, and to execute such a mitigating action.

20. A server as claimed in claim 19, wherein the mitigating action serves to reduce the latency in the connection.

21. A server as claimed in claim 19, wherein the mitigating action serves to reduce an effect on a user of the latency in the connection.

22. A server as claimed in claim 19, wherein the client component is operable to receive a profile list including multiple display parameters for a display device of the client device, wherein the parameters represent respective connection statuses.

23. A server as claimed in claim 19, wherein the client component is operable to receive a profile list including multiple display parameters for a display device of the client device, wherein the parameters represent respective connection statuses, and to adjust a parameter of the display device on the basis of the current status and according to the profile list.

24. A server as claimed in claim 19, wherein the client component is operable to receive a profile list including multiple display parameters for a display device of the client device, wherein the parameters represent respective connection statuses, and wherein the multiple display parameters include a resolution and colour depth for the display device.

25. A server as claimed in claim 19, wherein the client component is operable to receive data from the server device over the virtual channel, the data representing a time period between a timestamp in a message received by the server device from the client device and a current timestamp value of the server device.
