VIRTUAL LOCAL PRESENCE BASED ON L3 VIRTUAL MAPPING OF REMOTE NETWORK NODES

摘要

An apparatus for transferring data, comprising one or more processing circuitries connected to a first network and executing a first mapping agent having a Layer 3 (L3) address mapping of a destination node connected to a second network separated from the first network. The first mapping agent is configured to receive, from a source node via the first network, a first packet destined to the destination node, adjust the first packet to include a virtual L3 address assigned to a second mapping agent executed at the second network and associated with the destination node, encapsulate the adjusted first packet in an encapsulation packet comprising a traffic descriptor resolved according to the virtual L3 address, and forward the encapsulation packet to the second mapping agent which is configured to transmit the adjusted first packet extracted from the encapsulation packet to the destination node via the second network.
