Adaptive screen painting to enhance user perception during remote management sessions

A method, comprising:

• detecting a speed of a network connection between a virtual network computing (VNC) client and a VNC server, wherein detecting the speed of the network connection includes determining if the speed of the network connection is considered fast or if the speed of the network connection is considered slow;
• sending a FrameBufferUpdateRequest (FBUR) from the VNC client to the VNC server;
• wherein the FBUR requests the VNC server to identify changes in a display of the VNC server;
• receiving a FrameBufferUpdate (FBU) from the VNC server at the VNC client, wherein the FBU identifies changes in the display of the VNC server;
• and
• for fast network connections, processing all changes in the FBU before painting the screen to update the display of the VNC client;
• and
• for slow network connections, processing each change in the FBU and painting the screen to update the display of the VNC client before processing the next change in the FBU.

A virtual network computing (VNC) client, comprising:

• at least one processor, and a display and memory operationally connected to the at least one processor;
• wherein the memory includes instructions which when operated on by the at least one processor perform a process to control a VNC protocol, wherein the process to control the VNC protocol includes:
• sending a FrameBufferUpdateRequest (FBUR) through a network connection to a VNC server, wherein the FBUR requests the VNC server to identify changes in a display of the VNC server;
• receiving a FrameBufferUpdate (FBU) from the VNC server, wherein the FBU identifies changes in the display of the VNC server;
• and
• dynamically adapting a screen painting to update a display of the VNC client based on a speed of the network connection, and updating the display of the VNC client using the screen painting algorithm.
