Scope, complexity, and scale of even a single 5G network are massively larger than intoday’s network. The main challenge is automation on all levels of the 5G eco-system.Without it, the network simply will not work; neither for the anticipated scale nor for thedesired functional complexity.Fundamentally, automation is realized by a largely self-governed network bound tovaring business goals: its configuration, its services, how they are provided, and how it ismanaged. A governance model, ideally realized by policies, defines how these goals are implemented and monitored. Those policies can be low-level configuration parameters,mid-level strategies or high-level intents and goals. Using a mix of these policies impliestranslation between: top-down for realization and bottom-up for action/benefit andvalidation purposes. Networks and models must address multiple, diverse constituencies. Human intervention should be kept to a minimum (oversight). Management meansmonitoring and repair; not control. Classic self-capabilities are the benefits.
