摘要： For allowing a simple and reliable differentiation of UEs behind a GW from an AF side a method for providing access of an User End device (UE) to a service provided by an Application Function (AF) within a network structure is claimed, wherein the UE is authenticated by a Gateway (GW) to which the UE is attached and which provides access to the AF via a Broadband Access Network (BB Access Network). The method is characterized in that the GW informs a state database (SDB) on service flow requests to or from the authenticated UE towards the AF, that the GW additionally sends NAT (Network Address Translation) or NAPT (Network Address and Port Translation) binding information of a respective NAT or NAPT binding created by the GW regarding the authenticated UE and a respective service flow request to the SDB and that the SDB sends the NAT or NAPT binding information or an UE identifier to the AF, so that the AF—after having received the service flow request from the GW—can correlate the authenticated UE with the service flow request. Further an according network structure is claimed, preferably for carrying out the above mentioned method.

摘要： A method for operating a flow-based switching system in a network, including at least one network node designed to transport incoming network packets, in particular a switch (20) or a router, wherein the incoming network packets are matched to flows according to predefined policies, wherein a dynamic flow table (40)-primary flow table (50)-containing information about the flows' properties is computed inside the network node or externally and stored in a memory of the network node, is characterized in that another dynamic flow table (40)-backup flow table (60)-is computed and maintained in parallel, wherein the backup flow table (60) is more coarse grained than the primary flow table (50), and wherein the network node switches between employing the primary flow table (50) or the backup flow table (60) depending on the status of predefined observables. Furthermore, a corresponding flow-based switching system is disclosed.

摘要： A method for mounting a device at a server in a network includes attaching the device at an anchor. A virtualized connection is set up between the anchor and the server based on a predefined anchor configuration, Temporary device information is encoded into a network flow generated by the device. It is attempted to mount the device is attempted at the server. Functions and/or data are provided to the mounted device by the server based on a successful mounting. Another server is selected for mounting the device based on an unsuccessful mounting. The network flow of the device is identified and redirected to the selected server by installing one or more forwarding rules on one or more forwarding elements of the software defined network using the temporary device information for identification of the network flow of the mounted device.

摘要： A method for handling subscribers' network traffic between a CPE (customer premises equipment) and a broadband access network includes establishing a subscriber session between the CPE and a BNG (broadband network gateway, an entity within the broadband access network), to set up a network route between the CPE and the BNG. Data transmitted within the subscriber session are encapsulated into protocol frames. A NCE (network control entity) acquires a state of the subscriber session and updates network policies in at least one network entity on the network route based on the state of the subscriber session. A DEM (dynamic encapsulation module) decides, based on a DEM configuration, whether data sent to the broadband access network are encapsulated data within the subscriber session or are non-encapsulated data outside the subscriber session. The data are transmitted on a part of the network route and are handled according to the network policies.

摘要： A method for supporting a connection between a communication device and a destination device in a target network over intermediate network nodes, in particular in the context of Internet Protocol based communication, wherein data between the communication device and the destination device is transmitted via a tunnel established between the communication device or a base station connected to the communication device, as a first tunnel endpoint and a gateway in the target network as a second tunnel endpoint. One or more dummy packets are sent via the tunnel from the first tunnel endpoint towards the second tunnel endpoint, information is encoded in the packet headers of the one or more dummy packets, and at least one of the intermediate network nodes, upon receiving the one or more dummy packets, performs the steps of detecting and/or decoding the encoded information and performing a predefined action dependent on the encoded information.
