A method for supporting mobility of end-points in a network, in particular a TCP/IP network, wherein said network includes access networks and a core network, wherein said access networks are connected to said core network via a switch, preferably being configured to use the Open Flow protocol, wherein said core network provides connectivity among said access networks, wherein an end-point - migrating node - connected to one of said access networks - home network - migrates to another one of said access networks - foreign network -, wherein one or more controller entities, in particular Open Flow Controllers, are employed for controlling the switches of said access networks, wherein said one or more controller entities are able to play the roles of - a home controller that controls a home switch of said home network, - a foreign controller that controls a foreign switch of said foreign network and/or - a correspondent controller that controls a correspondent switch of a correspondent network, wherein, after migration of said migrating node from said home network to said foreign network, a new IP address - locator - belonging to said foreign network is assigned to said migrating node, wherein said locator is employed to find the current location of said migrating node in the network, wherein said migrating node's original IP address - identifier - belonging to said home network is employed to identify said migrating node, and wherein an identifier/locator mapping is employed and reactively updated at the controllers. Furthermore, a corresponding controller entity and a network are disclosed. |
