The rise of 5G has made network slicing more common, and this has an impact on how networks are constructed, maintained, and run. Various companies can now set up virtual networks tailored to their needs on a single physical base. Each of these virtual networks plays a part in overall performance by offering unique metrics for reliability, security, and speed. AI-driven orchestration and cloud-native design allow for better setup of real-time resource shifts and automatic service guarantees in core, RAN, and transport areas. This brings new challenges for managing the system's lifecycle and putting it all together, but smart automation, open APIs, and standard control systems help to overcome these hurdles.
