Abstract: Proposed are a computer-implemented method for accelerating convergence in the training of generative adversarial networks (GAN) to generate synthetic network traffic, and computer programs of same. The method allows the GAN network to ensure that the training converges in a limited time period less than the standard training period of existing GAN networks. The method allows results to be obtained in different use scenarios related to the generation and processing of network traffic data according to objectives such as the creations of arbitrary amounts of simulated data (a) with characteristics (statistics) similar to real datasets obtained from real network traffic, but (b) without including any part of any real dataset; diversity in the type of data to be created: IP traffic, network attacks, etc.; and the detection of changes in the network traffic patterns analysed and generated.

Abstract: The method comprising receiving, an ALTO server at a network layer, a request from an ALTO client at an application layer to obtain network cost for a connection; computing, the cost information concerning PIDs stored in the ALTO server and adapting, by a request controller, the computed cost information to an ALTO information further sending it to the ALTO server and the latter to said ALTO client; receiving, by a provisioning server, a request from a provisioning client to compute a path for setting up a connection between said PIDs and transmitting said request to a provisioning controller; mapping, the provisioning controller, said received request from the provisioning server into network addresses and computing said path according to said network addresses; and comparing, a network cost of the computed path with a cost information previously stored by the request controller in a request database.

Abstract: The method comprising, in a network based on a chain of individual Service Functions, SFs, that are composed to implement Network Services, NSs: assigning, at an ingress node of a network architecture, to at least one data packet received by said ingress node from the network, a unique cryptographic tag; processing said assigned unique cryptographic tag using a cryptographic function specific to each Service Function, SF; and verifying, at a given point of the network architecture, said processed unique cryptographic tag by applying a cryptographic verification function composed by the inverse functions of the cryptographic functions associated to the SFs traversed by the at least one data packet.
