摘要

An entity (4) processing or processing data units in a network (10) transmission of data units comprising a plurality of nodes (101-112) network, such that said nodes (101-112) network comprising routing nodes (101-109) and end nodes (110, 111, 112), said routing nodes (101-109) arranged to route data units (20, 30) over said network (10) being transmitting data units in accordance with a routing protocol (RP), and being one or more of said end nodes (110, 111, 112) mobile nodes (110, 111) able to access said network (10 ) transmission data units over a link, such that said network nodes are arranged to distinguish between a routing address of a first type (IA) and a routing address of a second type (FA) of said data units (20, 30), so that said first routing address type (IA) s irvepara identify nodes (101-112) and said network routing address of the second type (FA) serving to allow routing to mobile nodes (110, 111) of said body part, comprising (4) for processing data units decision (41), designed to establish the routing address of the second type (FA) in a received data unit (20, 30) that is to be forwarded, so that operation of said decision part (41) depends the routing address of the first type (IA) set in said received data unit (20, 30) that is to be forwarded, and data stored decision in association with said routing address of the first type (IA) a memory (42) decision data, such that said decision data comprises one or more routing addresses of the second type (FA), said entity (4) for processing data units further comprising a management part (43) for dich a memory (42) decision data, such that said management part (43) provides an interface to said memory (42) decision data, to modify said decision data, characterized in that said interface is arranged to provide a function (51) network control with access to said memory (42) data decision to modify said decision data, independently of access provided to one or more mobile nodes (110, 111).
