  • Patent number: 8347073
    Abstract: Systems, methods, and other embodiments associated with processing secure network traffic are described. One example method includes determining whether a device is a preconfigured member of a group key system. If the device is not a preconfigured member then the method selectively establishes membership in the group key system by requesting membership from a group controller. The example method may also include receiving a set of keys from the group controller and being assigned a role by the group controller. The method may further include processing secure network traffic as an inspection point, a rewriting point, and/or a validation point based on the received set of keys and the assigned role(s).

  • Patent number: 7869436
    Abstract: A system allows a device to communicate using a virtual network the method by assigning a network address to the device. The network address is selected from a plurality of network addresses that can be assigned to any of a plurality of virtual networks. The system receives a request to authenticate the device, and then determines a virtual network on which to assign the device. The virtual network is selected from the plurality of virtual networks. The system identifies the device as authenticated based on the assigning of the network address and the virtual network.

  • Patent number: 7688829
    Abstract: A routing mechanism provides network segmentation preservation by route distribution with segment identification, policy distribution for a given VPN segment, and encapsulation/decapsulation for each segment using an Ethernet VLAN_ID, indicative of the VPN segment (subnetwork). Encapsulated segmentation information in a message packet identifies which routing and forwarding table is employed for the next hop. A common routing instance receives the message packets from the common interface, and indexes a corresponding VRF table from the VLAN ID, or segment identifier, indicative of the subnetwork (e.g. segment). In this manner, the routing instance receives the incoming message packet, decapsulates the VLAN ID in the incoming message packet, and indexes the corresponding VRF and policy ID from the VLAN ID, therefore employing a common routing instance over a common subinterface for a plurality of segments (subnetworks) coupled to a particular forwarding device (e.g. VPN router).
