Manner and the device in order to joint the subscriber device to agurigeshiyonnetsutowaku of IPv6 correspondence

摘要

The present invention relates to an access node (2) for connecting a subscriber device (1) to an IPv6-capable aggregation network (3), and adapted to receive an upstream IPv6 packet (NS1O; RS1O; NA1O) comprising an IPv6 address (LLIP@O) held by the subscriber device. An access node according to the invention is further adapted to assign a new interface identifier (IDT) to the subscriber device that is unique within the scope of a L2 communication domain (6), which the subscriber device belongs to, to substitute, within the upstream IPv6 packet, the new interface identifier for an original interface identifier (IDO) of the IPv6 address and thereby yielding a translated upstream IPv6 packet (NS1T; RS1T; NA1T) comprising a translated IPv6 address (LLIP@T), and to forward the translated upstream IPv6 packet towards the aggregation network. The present invention also relates to a method for connecting a subscriber device to an IPv6-capable aggregation network.
