SYSTEM AND METHOD FOR ADDRESS AND KEY DISTRIBUTION IN VIRTUAL NETWORKS

摘要

A system and method for resolving endpoint addresses and security credentials in virtual private networks (VPNs) based on a combination of server based address resolution and key distribution. The virtual network comprises a first (C3) and a second client (C2), and a server (S), in which server records are stored comprising address information for said clients. The address information in a record for a certain client comprises that client's global address in a physical global network, preferably an IP network such as the Internet, on which the virtual network resides. Preferably the address information in a record for a certain client comprises a tunnel terminator address together with a VPN id/port corresponding to a physical endpoint for that client to which data is transmitted, and security credentials for accessing that client.
