Windows XP based driver and client maintenance

Project Period & Property

Improvements and bug fiexs for about 10 months.

Background

“ENTO Networks” used Windows XP based client as its main product.
Until the next version development, we had to improve and maintain the product.

Check

• HSSP (Hot Stand by Switching Protocol).
  • A proprietary protocol for communication between the driver and the client.
  • Check speed with VPN server to help switch to faster VPN line.
  • Proper algorithms are needed to prevent wasted switching.
• How to test and debug using network drivers.
  • Remote debugging with WinDBG is possible because the system may hang when testing the driver.
  • If the VPN client is not working, I should treat it so that it does not wrap packets.

Technical Summary

• Register the callback function appropriately to avoid system panic.
• Improved HSSP algorithm.
