Abstract: A method for delivering at least one data packet is disclosed originating from a corresponding node in a corresponding network to a mobile node having a home network and being connected to a foreign network different from said home network, the mobile node having a long term IP address belonging to said home network and a care-of-address being the address of an foreign network access router of said foreign network, said networks being connected to an IP network comprising at least one data storage, by respectively a home network access router, a corresponding network access router, and said foreign network access router, the method comprising: a. intercepting said at least one data packet and detecting the destination IP address thereof; b. consulting said at least one data storage, whereby said care-of-address of said mobile node is retrieved by using the destination IP address of said at least one packet; c.

Abstract: The invention discloses a method to control a resynchronization trigger in an access device (40). A management station (43) is connected to the access CPE (40) via a control channel (50). The CPE is able to receive a control signal including application information and to calculate the synchronization trigger where the application information is used.

Abstract: The present invention relates to an access unit for coupling a plurality of subscribers to a data communication network, and comprising an auto-configuration control unit adapted to learn, from first auto-configuration data issued by an auto-configuration server and transiting through said access unit towards a particular subscriber coupled to said access unit, a particular network address as being dynamically assigned to said particular subscriber.

Abstract: The invention relates notably to a method for enabling a user registered in an Network Access Server as already connected to a Virtual Private Network to communicate with at least a communication device not belonging to the Virtual Private Network. The Network Access Server enables access over a data communication network to the communication device as well as to a plurality of Virtual Private Networks.
