IP security with seamless roaming and load balancing |
摘要 |
Described are a method and system for seamless roaming of a mobile node during a VPN session. A VPN session between the mobile node and a current VPN server in a network is established and synchronized with at least one fail-over VPN server in the network. An address change message is sent to the current VPN server and the fail-over VPN servers upon roaming of the mobile node. A fail-over VPN server responds with a reply message and is registered as a current VPN server for continuation of the VPN session. To load balance, a load query message is sent to the current VPN server and the fail-over VPN servers. Reply messages include server performance characteristics of the VPN servers. The VPN session can be transferred from the current VPN server to a fail-over VPN server in response to the server performance characteristics.
