  • System and method for connecting geographically distributed virtual local area networks
    Patent number: 7088714
    Abstract: A VLAN tagging unit associated with a WAN is used to add VLAN tags based upon logical interfaces. In one example, data received across the logical interface is tagged with an associated VLAN ID by the unit. In another embodiment, flow-based VLAN tagging is done in which in addition to the logical interface other indications are used in the VLAN tagging.
    Type: Grant

  • Internetwork address mapping gateway
    Patent number: 5856974
    Abstract: The present invention is an address mapping gateway, used in an internetwork link, that associates all nodes in a domain with a single network number (referred to as a domain network address), and provides gateway-mapped node addresses that are unique within the domain. The address mapping gateway dynamically substitutes the "globally-unique" domain network address and the "domain-unique" gateway-mapped node address for a network number and node address, respectively, of a network layer address of a packet header received from a source node in the domain. Conversely, when a packet is received for a destination node in the domain, the address mapping gateway substitutes the originally-assigned network number and node address for the domain network address and gateway-mapped node address, respectively, prior to forwarding the packet to the node.
