Mobility γ Z C X A1 Y B α γ Z C Y B α R ⇒ R δ β δ Figure 2. X disconnects from location A1 and reconnects at location A2 What is “X”? X represents the identity (ID) of the node 1 • in an Ethernet it might be the MAC address, thus a node has a constant identity X A2 β While A1, A2, … represent the network addresses of node X. • IP network address consists of {Network, Host}, i.e., A1={α | n}, where n is unique on network α. 1. Of course this really mixes the interface ID with the node ID - solution is a Network Access Identifier[1].
