Routing between software defined networks and physical networks
First Claim
1. A method for routing packets between a physical network and a software defined networking network (SDN network), the method comprising:
- receiving, at a data link layer (layer
2) gateway device configured to connect the physical network to the SDN network, routing data to a computing device of the two or more computing devices, the computing device selected to receive a packet transmitted from the physical network to the SDN network;
receiving, from a source element in the physical network, an address request for a layer 2 address of a router element in the SDN network, the address request including a networking layer address of the router element;
transmitting, to the source element in response to receiving the address request, the layer 2 address of the router element using the routing data;
receiving, from the source element, a routing request to route the packet to a destination element in the SDN network using the layer 2 address; and
routing, using the routing data, the received packet to the selected computing device.

Abstract
A method includes receiving, at a data link layer (layer 2) gateway device configured to connect the physical network to the SDN network, routing data to a computing device, the computing device selected to receive a packet transmitted from the physical network to the SDN network; receiving, from a source element in the physical network, an address request for a layer 2 address of a router element in the SDN network, the address request including a networking layer address of the router element; transmitting, to the source element in response to receiving the address request, a layer 2 address of the router element using the routing data; receiving, from the source element, a routing request to route a packet to a destination element in the SDN network using the layer 2 address; routing, using the routing data, the received packet to the computing device to route to the destination element.
