A method and system for multi-factor authenticating users in Web3 services includes a multi-factor authentication (e.g., 2FA) provider configured to validate that an end-user owns a public key in a blockchain based on a cryptocurrency or a NFT transference, the public key used as a first factor for the authentication. The authentication provider interacts with a smart contract to perform the multi-factor authentication in an operation in a smart contract by using off-chain data as the other factor(s) required for the multi-factor authentication. The off-chain data are received in a user terminal, e.g., a smartphone via SMS or a mobile application, associated with the account created in the authentication provider. The authentication result is read by each node executing the smart contract and, when a consensus is reached among nodes, a new block representing the result is generated in the blockchain.

A method and an orchestration server for packet data network service slicing over a network infrastructure for real-time IP services are provided. The method comprises providing an orchestration server that has knowledge of a whole connectivity status of a network infrastructure and that is configured to manage service nodes. The server receives a session request for a real-time IP service from a UE device located in a given region and requests to one or more service nodes of said given region whether it has/they have network resources. Each of the one or more service nodes compute a QoS measurement thereof in terms of KPIs including latency, jitter and bandwidth, the QoS measurement being computed by a software module that is implemented on a virtual machine deployed on the service node; and tag a plurality of interfaces. The orchestration server selects a given service node in view of said QoS measurement.

The distribution network comprising a plurality of caching nodes and wherein the web content had been statically identified as an uncacheable content and originated on an origin-server and wherein the method establishes a time to live, TTL, period value to said uncacheable content based on users requests and responds to said users requests by sending to at least to one CDN user said uncacheable content within said TTL period value. Each one of said plurality of caching nodes in said distribution network including a content caching manager and a pseudo-dynamic content TTL predictor and performing the following steps: The system of the invention is arranged to implement the method of the invention.

A computer implemented method and network device for tracking OPT-OUT user preferences in a global communication network and computer programs thereof, The method comprising performing, by at least one a user, at least one operation request for a service of an online system (); tracking, by a network device (), said operation request and detecting if it is linked to a tracking mechanism, wherein: a) if it is not linked to a tracking mechanism, said network device (), bypasses the operation request to said online system () without performing any action; or if it is linked to a tracking mechanism, the network device (), identifies whether an OPT-OUT or an Opt-In status related to the user is included in the operation request and sends or not the operation request to a tracking server () depending on the result of said identification.

Computer-implemented method, a network device and computer program products for tracking OPT-OUT user preferences in a global communication network

A distributed health-check method for web caching in a telecommunication network, wherein a plurality of web caching nodes are coordinated to monitor a set of origin servers where web content is generated. The method includes associating to each user of the telecommunication network requesting the web content buckets as logical containers for holding the web content requested; generating a list of users of the telecommunication network requesting the web content; and performing the plurality of web caching nodes a number of health-checks to the set of origin servers to download the requested web content. A filtering of the set of origin servers is performed for grouping in different areas of interest and the number of health-checks are performed by a limited number of caching nodes receiving the web content requests. The limited number of caching nodes selected belonging to a specific area of interest of the set of origin servers monitoring them.

In the method, a plurality of access points forming a cluster in a telecommunication network monitor network data traffic information from at least one user computing device connected thereto; report an own identifier and a used public IP to a remote server recording them; establish connections between access points in said cluster by mapping the own identifier with said public IP; determine its internal status and state of the connection of said at least one monitored user computing device; generate, each certain time-frequency, a profile; calculate, in a determined time T1, a forecast of future requirements of the own access point and send to one access point of said plurality acting as a cluster coordinator said calculated forecast, wherein said coordinator defines a routing path through carrying out associations of access points to which perform the backhaul aggregation.

Method for access points scheduling for backhaul aggregation in a telecommunications network and a device

In the method, a plurality of access points forming a cluster in a telecommunication network monitors network data traffic information from at least one user computing device connected thereto; obtains a status profile; reports an own identifier to a remote server; builds, by using a record including the corresponding identifier of each access point, a list of access points available for performing backhaul aggregation; and establishes connections between available access points forming sub-clusters of access points. Wherein, one of the access points acts as a cluster coordinator coordinating said formed sub-clusters of access points for a backhaul aggregation. The device is adapted to implement the method.
