Abstract
A method for handing-off a mobile node (MN) from one network interface to another network interface, the network interfaces being connected to a same level 2 (L2) network. The method includes detecting at least two network interface cards (NICs) of the MN that are connected to the same L2 network by at least one of an external device and the MN. A handover decision is made to hand-off a data flow of the MN from a first of the at least two NICs to a second of the at least two NICs. L2 information about the MN in one or more related network entities connected to the same L2 network is updated so as to perform seamless handover without changing an address on level 3 (L3) or higher levels.
