Abstract

A method for monitoring remote access connection latency between a client device and a server device comprises using a virtual channel between the client device and the server device to determine a value for the latency in a network connection therebetween.

Claims

1. A method for monitoring remote access connection latency between a client device and a server device, comprising:

using a virtual channel between the client device and the server device to determine a value for the latency in a network connection therebetween.

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

3. A method as claimed in claim 1, further comprising compiling a limited running list of historic latency values, and using the list to determine an average value for the latency between the client device and server device.

4. A method as claimed in claim 1, further comprising:

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

providing multiple threshold values representing respective different connection statuses;

assigning a status for the connection using the average value; and

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

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

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

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; and

providing 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.

6. A method as claimed in claim 1, further comprising:

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

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;

providing 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; and

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

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; and

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

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

9. A method as claimed claim 1, wherein the network connection is a TCP connection.

10. A server device comprising a server component operable to receive data from a client device over a virtual channel, the data representing a value of latency in a network connection for remote access between the client device and the server device, and to use the latency value to update a visual representation of the latency for the client device.

11. A server device as claimed in claim 10, 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 using the network connection.

12. A server device as claimed in claim 10, 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.

13. A server device as claimed in claim 10, 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, to provide multiple threshold values representing respective different connection statuses, to assign a status for the connection using the average value, and to increment or decrement a counter associated with the statuses based on the assigned status to provide a current status for the connection.
