Abstract
Since the dawn of the computer age, the amount of data our machines can process continues to grow relentlessly. To efficiently process applications such as AI, connected vehicles, AR/VR, and smart factories, computation must move ever closer to data that grows ever more massive. In computer science, this is a fundamental principle known as “data locality.” In future networks, we know it as edge computing.
In this chapter, we cover solutions to challenges posed by edge computing in future networks. We define the relationship between edge computing and 5G and MEC, and interfaces to Telco core networks and Hyperscaler public clouds. We look at access and edge components, including the “far edge.” From a business perspective, we identify revenue-driving applications and services, and latency-sensitive services vs. data sensitive. From a technical perspective, we describe edge architecture, including the concepts of an edge border gateway and federation (both edge-edge and edge-cloud), and key enabling technologies.
