Maestro Policy Engine and PSM details the transition from PacketLogic Subscriber Manager (PSM) to a modern, CUPS-compliant, 5G-ready control plane. The migration introduces enhanced scalability, cloud-native architecture, and advanced policy control with real-time charging and subscriber awareness. Unlike PSM’s limited active-passive model, Maestro supports active-active clustering, horizontal scaling, and improved performance metrics such as higher mapping rates and lower latency. It enables seamless integration with 5G NSA and SA deployments, supports hybrid cloud environments, and leverages SandScript for flexible policy automation. This evolution empowers operators to modernize networks, improve efficiency, and support future-ready services.
