Introduction

During the last decades, digital communication networks have become the basis of many applications in everyday life. This digital transformation process will most likely continue in the future, as supposedly additional services will be built upon digital computer networks, such as autonomous driving, smart manufacturing, or medical care [2, 8, 33]. The challenges during the COVID pandemic and the accompanying rise of remote work have shown the importance of reliable and performant communication networks. Connecting billions of people worldwide via digital video presence requires low latency and high throughput connectivity.
