COMMUNICATION SYSTEM, PROVIDER NODE, COMMUNICATION NODE AND METHOD FOR PROVIDING A VIRTUAL NETWORK FUNCTION TO A CUSTOMER NODE
FIG4 represents a flowchart of a method for activating a virtual network function
FIG4 shows a flowchart of a method for activating a virtual network function of a data network, the method according to an embodiment of the invention. The method may be split up, as illustrated in FIG4, into a method 300 for operating a customer node 200 and a method 400 for operating a communication system 100. Furthermore, FIG4 schematically illustrates a distributed database 20 and a data repository system 30. The communication system 100, the customer node 200, the distributed database 20 and the data repository system 30 are each according to an embodiment of the present invention and may in particular be according to exemplary embodiments given with reference to the preceding figures.

['1. A provider node (110) comprising: a retrieving module (112) adapted to retrieve a notification signal, the notification signal being indicative of a selected one of a plurality of virtual network functions and at least one customer node to which the selected virtual network function is to be provided; a validation module (114) adapted to establish service level agreement data, the service level agreement data at least representing a configuration of the selected virtual network function and the at least one customer node, and to validate the service agreement level data, based on the notification signal; and a deployment module (116) adapted to selectively transmit a deployment signal to a communication node depending on the validating of the service level agreement data for providing the selected virtual network function to the at least one customer node, the deployment signal being indicative of the at least one customer node, the selected virtual network function and its configuration.', '15. A method (300) for operating a customer node (200) for a data network (10), wherein the data network is adapted for providing a plurality of virtual network functions to the customer node by means of a communication system (100), the method comprising: - (310) selecting one of the plurality of virtual network functions as a selected virtual network function; - (312) reporting the selected virtual network function to a distributed database; and - (316) establishing a data communication via the selected virtual network function, when (314) it is provided by the communication system.']
