Abstract
A wireless electronic device includes a first application to output a first packet through a first virtual interface as a wireless electronic device moves from a home subnetwork to a foreign subnetwork. The wireless electronic device also includes a second application utilizing the Mobile Internet Protocol (Mobile IP protocol) to output a second packet through a second interface as the wireless electronic device moves from the home subnetwork to the foreign subnetwork. A common physical interface is tied to the first virtual interface and the second interface of the wireless electronic device, wherein the physical interface of the wireless electronic device receives the first packet and the second packet, and outputs the first packet and the second packet from the wireless electronic device after the wireless electronic device has moved.
