Abstract
A computerized method is provided for automated routing of active virtual private network sessions. Methods can include modules to actively monitor, through periodic polling, internal connections to remote resources for the site of a VPN appliance. Upon detecting sufficiently impaired connectivity via the internal connection, the VPN connections optimization tool can automatically disable the external interface on affected VPN appliances to force disconnections of VPN clients and rerouting to available VPN appliances with functioning internal links.
Claims20
A computerized method for routing virtual private network (VPN) sessions, the method comprising:
- providing a computer network data center comprising a plurality of zones, each zone comprising a VPN connections optimization tool and one or more VPN appliances operable to securely connect a VPN client to the data center,
- wherein each zone is connected to one or more remote resources by a multiprotocol label switching (MPLS) link;
- wherein the VPN connections optimization tool at a first zone is operable to perform the steps of:
- periodically polling availability of a first zone's MPLS link;
- receiving a threshold number of consecutive network down responses in response to the periodic polling;
- and
- subsequently initiating a VPN connections failover process.
A computer system for routing virtual private network (VPN) sessions, the system comprising a computer network data center comprising a plurality of zones,
- wherein each zone comprises a VPN connections optimization tool and one or more VPN appliances operable to securely connect VPN clients to the data center,
- wherein each zone is connected to one or more remote resources by a different multiprotocol label switching (MPLS) link;
- and
- wherein the VPN connections optimization tool at a first zone is operable to perform the steps of:
- periodically polling the first zone's MPLS link's availability;
- receiving a threshold number of consecutive network down responses in response to the periodic polling;
- and
- subsequently initiating a VPN connections failover process after the receiving step.
