摘要： In a processing management or control messages in a packet or cell switched data network, a protocol packet (131) is provided with a selection identifier that indicates the sub-system (145) of the receiving network element (102), which sub-system operates the management and/or control session connected to said protocol packet. Now that sub-system (144) of the receiving network element that receives said protocol packet (131), is capable of conducting the information contained in said protocol packet to the appropriate sub-system (145) of the receiving network element (102) on the basis of said selection identifier.

摘要： A method for controlling advertising of routing data to neighbor routers is presented. A list of prefixes is maintained (301) and each prefix is associated (302) with an own indicator vector that contains a data item for each of the neighbor routers so that the data item indicates (304) whether the prefix concerned is to be advertised to the neighbor router concerned. For each neighbor router there is (303) a handling pointer pointing to the prefix that is relevant to the status of an advertising process related to this neighbor router, and the handling pointer is moved forward on the list of prefixes according as the prefixes are advertised to this neighbor router. As there is no need to maintain an own list of prefixes for each neighbor router separately, but only neighbor router-specific entries in the indicator vectors, savings can be achieved in the required memory space.

摘要： A network element (101-104) of a software-defined network is adapted to construct a configuration system on the basis of configuration data received from a controller (105, 106) of the software-defined network. The network element is arranged to transmit, in response to an event indicating a need to verify the configuration system, status information to the controller. The event may include for example a loss and a subsequent reestablishment of a connection between the network element and the controller. The status information indicates a first portion of the configuration data which has been implemented in the configuration system prior to the event. After receiving the status information, the controller is able transmit an appropriate second portion of the configuration data to the network element so as to enable verification of an appropriate portion of the configuration system. Thus, there is no need to verify the whole configuration system after the event.

摘要： A network element of a software-defined network includes functional entities (321-325) capable of transferring data between each other and providing connections to other network elements. One or more of the functional entities are configurable with configuration data received from a controller of the software-defined network. The network element is adapted to transmit, to the controller, entity-specific capability descriptors related to the functional entities configurable with the configuration data. Each entity-specific capability descriptor expresses operations capable of being carried out by the respective functional entity. As the controller is made aware of the capabilities of the functional entities, the goal of the software-defined networking to provide controlled management of the data-forwarding functionality of a network element as a whole can be extended to the functional entities, e.g. line interface modules, so that each functional entity can be configured individually in accordance with the capabilities and resources of the functional entity.

摘要： The present invention relates to providing virtual private network (VPN) services between two or more Autonomic Systems (AS). An aggregation edge router (ASBR) is provided in two or more autonomous systems (Asx,Asy). The aggregation edge routers are configured such that routing peering between the two or more autonomous systems is done between the aggregation edge routers in these autonomous systems. Each aggregation edge router is a routing peer of other edge routers (PE) in its own autonomous system. The Multi-Protocol Label Switching (MPLS) network is used between the different autonomous systems.
