Abstract: A system and method for training and validating ML algorithms in real networks, including: generating synthetic traffic and receiving it along with real traffic; aggregating the received traffic into network flows by using metadata and transforming them to generate a first dataset readable by the ML algorithm, comprising features defined by the metadata; labelling the traffic and selecting a subset of the features from the labelled dataset used in an iterative training to generate a trained model; filtering out a part of real traffic to obtain a second labelled dataset; and selecting a subset of features from the second labelled dataset used for validating the trained model by comparing predicted results for the trained model and the labels; repeating the steps with a different subset of features to generate another trained model until results are positive in terms of precision or accuracy.

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.

Abstract: A system and method for validating proof of transit of network traffic through network nodes (N), the node (N) comprising a set of input interfaces (20) receiving incoming packets, a first module (A) to identify a matching route within a routing table (23) and storing means (22) to provide next modules (B, C, D) with two private keys if the packet is matched and/or the packet metadata includes OPoT information. The second module (B) decrypts the OPoT metadata using the first private key associated to the link of the node from which the incoming packets are received. The node (N) has SSS metadata to be processed by a third module (C) for the correct generation of cumulative validation parameters. When the SSS process is finished by the third module (C), the fourth module (D) re-encrypts the OPoT metadata using the second private key before packet forwarding to the subsequent node in the path through output interfaces (21).

Abstract: Conductive, elastic ionic polymers with high tensile strength (iono-elastomers) resulting from amphiphilic polymers capable of self-assembly into micellar hierarchical gel-like structures in an electrically conductive liquid are provided. The micellar hierarchical gel-like structures engage in micellar corona cross-linking to form the iono-elastomers. The iono-elastomer exhibits high stretchability and displays increased electrical conductivity upon mechanical stretching. A method for producing iono-elastomers includes mixing amphiphilic polymers in a conductive liquid to form micellar hierarchical gel-like structures, and cross-linking the micellar coronas. Devices incorporating iono-elastomers and methods for creating such devices are also provided. The devices incorporating the iono-elastomers may be wearable.

Abstract: Bottlebrush poly(alpha olefin)s of high carbon number, greater than 12 such as poly(octadecene), are used as a thickener for a synthetic base oil grease lubricant that is based on oligomerized alpha olefin with carbon number from 7 to 12, such as oligo(decene). Dispersion aids are not required in the present lubricants because poly(octadecene) can be dissolved in oligo(decene). The lubricant is a solid grease formed by percolation/network of the poly(octadecene) crystals, at a sufficient concentration, after the crystallization of poly(octadecene), and water resistant having oxidation/high temperature stability.
