During the 2023 5G Core Network Summit, GlobalData, a world-renowned consulting firm, released the High-Stability Core Network White Paper together with AIS, Entel, Sunrise, T\u00fcrk Telekom, and Huawei. The white paper is industry\u2019s first to systematically analyze the reliability challenges faced by cloud-native core networks and propose a core network reliability standard to classify different health states. It provides a frame and methodology for a high-stability network.<\/p>\n\n\n\n
As 5G and cloud technologies evolve, services become more diversified. At the same time as the emergence of these technologies are software and hardware decoupling, multi-generation coexistence, complex inter-generation APIs, signaling surge, transport network faults, as well as data center faults which are exerting greater pressure on operators to maintain carrier-grade reliability of the core network. According to GlobalData, 42% of operators have experienced core network service interruptions in the past three years, and the interruption frequency increases annually.<\/p>\n\n\n\n
Based on four common network metrics: traffic, latency, errors, and saturation, the white paper classifies core network health states as Normal, Pre-warning, Subhealth, Overload, Single NF Fault, and Multiple NF Fault<\/strong>. It proposes the core network reliability standard \u201cSTABLE\u201d, where different measures are taken at different network phases to ensure that incidents do not accumulate or escalate, showing a systematic methodology to enhance the reliability of the core network.<\/p>\n\n\n\n Furthermore, the white paper defines network reliability by three levels in descending order: Level-1<\/strong> No serious accidents, Level-2 <\/strong>Zero interruption of mission-critical services, and Level-3<\/strong> Deterministic high stability. With this, operators can better understand their network anti-risk capability and perform security hardening in a timely fashion.<\/p>\n\n\n\n Huawei will continue to work with partners to promote industry development and build a highly stable and reliable core network, laying a solid infrastructure foundation for a fully connected, intelligent world.<\/p>\n\n\n\n\n
