This document presents recent advancements in network and service management, focusing on key frameworks and interfaces towards open, intelligent and reliable 6G networks. The content reflects the work that has been done in various SNS JU projects , all of them converging to a key message; there is a need for open software solutions and standardized interfaces that can facilitate the development of the new era in network and service management. The document is structured in three main sections, namely Section 2, 3 and 4, covering respectively: programmability (exposure services and interfaces), management (end-to end automated management over a compute continuum) and security (secure orchestration including privacy and trustworthiness considerations) enablers for 6G telecommunication networks and systems.
