Abstract: The disclosure relates to a computer-implemented method and control system for controlling provisioning of a service in a network. A network function specification data structure of a network function of the service is obtained, wherein the network function specification data structure is associated with at least a first network function implementation, e.g. a physical network function implementation, and a second network function implementation, e.g. a virtual network function implementation, for performing the network function of the service. Network service provisioning is controlled comprising selecting the first network function implementation or the second network function implementation of the network function in the network function specification data structure.

Abstract: A method for requesting a plurality of chunks by a streaming client on the basis of a single request message is described, wherein said chunks are defined on the basis of a manifest file comprising chunk identifiers for determining at least one delivery node for delivering chunks defined by said chunk identifiers to said client, wherein said method comprises: determining on the basis of said manifest file a first request message for requesting a first plurality of chunks, said first request message comprising one or more first chunk template parameters and a first chunk template, preferably an URL chunk template, comprising one or more chunk template parameters fields; sending said first request message to a first network node, wherein said first network node is configured for determining a first plurality of chunk identifiers, preferably a first plurality of URLs, associated with said first plurality of chunks on the basis of said first chunk template and said one or more first chunk template parameters; and

Abstract: The invention pertains to a method for determining transmission parameters in a wireless local area network operating under a restricted access window scheme, said wireless local area network comprising an access point and a plurality of stations, the method comprising at said access point: estimating (230) respective transmission intervals and next transmission times of said plurality of stations; and assigning (260) a subset of said plurality of stations to a restricted access window group on the basis of said estimated next transmission times. The invention also pertains to a computer program product comprising code means configured to cause a processor to carry out the method and an access point configured to carry out the method.

Abstract: The disclosure relates to a computer-implemented method for controlling on-demand service provisioning in a network, wherein the network comprises resources for providing a service. In the method, a service request is intercepted. At least one network function, indicated as a first network function, required for the service associated with the service request is determined. Then, the first network function is instantiated on a resource in the network for executing the service in the network.

Abstract: A method and system for enabling a plurality of adaptive streaming client devices to share network resources includes a network node monitoring chunk request messages of client devices configured to select a quality level of a chunk from a plurality of quality levels and to request a media server for transmission of a chunk of the selected quality level. The quality level in a monitored chunk request message of a client device is used to estimate local quality information associated with the quality performance of the client device. Global quality information, determined based on the estimated local quality information associated with the client devices, and being indicative of the global quality performance of the client devices, is sent to the client devices.

Abstract: A method for providing chunked content to a device having a streaming client, chunked content defined on the basis of a manifest file having chunk identifiers and associated chunk locators for locating delivery nodes configured to deliver chunks identified by the chunk identifiers. Whether a chunk identified by a chunk identifier in a chunk request message originating from the client can be delivered by a first delivery node is determined, the request message including a first network address associated with the first node. If the first node cannot deliver the chunk to the client, the first address is rewritten into a second network address associated with a delivery node capable of delivering the chunk before sending the request message to the second node. Before sending a chunk response message associated with the request message to the client, the second address in the response message is rewritten into the first address.
