摘要： The present invention discloses a virtual private network (VPN) implementation method and system. The implementation of the VPN is based on the Location/ID separation network, and the corresponding VPN attribute is added to the mapping relation between the ID identifier and the location identifier. When performing the mapping processing, if the VPN attribute of the source host is judged to be the same as that of the destination host, the location identifier of the destination host is inquired, thereby the forwarding of the data packets is implemented according to the location identifier of the destination host; if the VPN attributes are not same, an unavailable message is replied. Thus, the virtual private network is implemented efficiently, the convenience and safety of the host communication of the VPN side are ensured, and the user requirement to the virtual private network is satisfied.
