Abstract
Virtual Private Network (VPN) tunnel redirection is accomplished by automatically redirecting tunnel initiator or network source for incoming call to another tunnel terminator or network destination according to traffic load, resource availability, or system reliability in VPN environment. Pointed terminator redirects call by sending special call clear message to tunnel initiator with IP address of recommended terminator in pool or set during PPP authentication. Initiator terminates current session with pointed terminator, establishes tunnel and/or session with recommended terminator, and starts processing again without terminating incoming call.
