Group Virtual Private Networks (Group VPNS) are provided for different types of machines in a data processing network. Security groups are defined by a security policy for each member. Security policies and encryption keys are deployed to members of a security group using an IPSec network infrastructure with authentication via VPN mechanisms. The group VPNs provide a trusted IP network that can leverage and co-exist with security access control technologies, such as endpoint security that controls client network access or application security that controls user access to enterprise applications.

Deploying group VPNS and security groups over an end-to-end enterprise network

Encryption of Internet Protocol (IP) traffic using IP Security (IPSec) at the edge of the enterprise network, in such a way as to support resilient BGP/MPLS IP VPN network designs. The IP traffic is securely tunneled within IPSec tunnels from the edge to the edge of the enterprise network. The IPSec traffic is also tunneled within MPLS tunnels from the edge to the edge of the service provider network. The enterprise network thus manages its own IPSec site-to-site VPN. The service provider thus independently manages its own MPLS network. The result provides an IP VPN or Layer 3 MPLS VPN to the enterprise; the enterprise IPSec network can thus be considered as an overlay to the MPLS service provider network.

IP encryption over resilient BGP/MPLS IP VPN

Encryption of Ethernet/IEEE 802.3 packet data units (PDUs) at the edge of the enterprise network, in such a way as to support resilient Virtual Private LAN Services (VPLS) network designs. The Ethernet traffic is securely tunneled within encrypted Ethernet tunnels from the edge to the edge of the enterprise network. The encrypted Ethernet traffic is also tunneled within Multi-Protocol Layer Switching (MPLS) tunnels from the edge to the edge of the service provider network. The enterprise network thus manages its own Ethernet site-to-site Virtual Private Network (VPN). The service provider thus independently manages its own MPLS network. The result provides a VPLS or Layer 2 MPLS VPN to the enterprise; the enterprise Ethernet encrypted network can thus be considered as an overlay to the MPLS service provider network.
