摘要：A method and system for enabling interconnection of VPNs is disclosed. An
interconnection device manages an interconnection process at one or more facilitiesincluding, for example, a gateway device. The gateway device has information relating to aplurality ofVPNs, and may facilitate interconnection between devices on at least two ofthe VPNs by determining that one device is in fact a member of a first one of the VPNs,and by forwarding connection parameters of the first VPN to the second VPN on an as-needed basis. In this way, the gateway allows interconnection without the need for acompletely centralized decision-making process, and does so independently of the typeof device and/or VPN(s) being used. Moreover, the gateway may implement only thoseVPN parameters needed by both VPNs to communicate with one another with a desiredlevel of security, thereby simplifying the routing and forwarding processes associatedwith the actual communication occurring via the interconnection. The information relatedto the plurality of VPNs and their respective member devices may be stored in a mappingtable at the gateway, and identification parameters of a device seeking interconnectionand/or associated VPN parameters may be verified by the use of digital certificates.
