Legacy generations of networks have predominately provided services with best-effort delivery. While this has worked for voice, text and best effort broadband services, end users are hampered with buffering, delays, and drops as the demand for feature-rich services continues to grow.
The 5G-era promises new feature-rich services – from ultra-broadband to the mass IoT connectivity required to enable a smarter world, and services such as driver assistance, remote surgery and immersive education. In this era, best-effort delivery is no longer good enough. Each of these services has a unique mix of policy and performance parameters for capacity, latency, packet delay variation, availability, security, and service and network isolation.
