Systems and methods for monitoring a network slice are provided. A method, according to one implementation, include extracting information from network traffic received from one or more User Plane Function (UPF) components of a network slice; examining the extracted information using Machine Learning (ML), and, in response to detecting of one or more malicious threats based on the examined extracted information by the ML, causing one or more actions to isolate the network traffic to protect at least the network slice from the one or more malicious threats.

Systems and methods for discovering the connectivity topology of cross-layer links in a multi-layer network are provided. In one implementation, a method includes a step of obtaining input data related to a plurality of Network Elements (NEs) operating in a plurality of layers within a multi-layer network having one or more cross-layer port-to-port connectivity links therebetween. The method also includes the step of utilizing Machine Learning (ML) processes and the input data to discover the one or more cross-layer port-to-port connectivity links between pairs of NEs operating in different layers of the plurality of layers within the network.

Network service providers have largely addressed the growth in demand for communications networks in two ways: employing faster and more robust communications protocols through equipment upgrades and increasing use of Operations, Administrations, and Management (OAM) procedures for improved network performance. Typically, OAM operations procedures used by a network protocol are unique to that protocol and are not compatible with other network protocols. Service providers with networks that use multiple communications protocols, such as networks using legacy and newly installed equipment, can have difficulty ensuring optimal performance due to non-compatible OAM operations. A method, and corresponding apparatus, for supporting OAM interworking between first and second communications protocols used in an interworking circuit of a communications network is disclosed. The method, or corresponding apparatus, allows network service providers to ensure optimal network performance in a manner that does not affect customer traffic, is transparent to customers, and can be seamlessly integrated into existing interworking network nodes.
