Claim 15:
16. The method of claim 15, further comprising:
receiving the frames of data passed across the fiber optic cable;
unpacking the third encapsulated frame to extract the first encapsulated frame and the identity of the virtual exit device;
determining whether the first hop device is the virtual exit device;
when the first hop device is the virtual exit device, unpacking the first encapsulated frame to extract the first frame of data from the first source;
when the first hop device is not the virtual exit device, determining a next hop device from the identity of the virtual exit device;
when the next hop device is a virtual forwarding device, encapsulating the first encapsulated frame to form a fifth encapsulated frame having a header that identifies the virtual forwarding device; and
when the next hop device is a network-to-network interface device, forwarding the first encapsulated frame to the network-to-network interface device.
