The Cloud Based 5GC – From Theory To Practice

Last year I wrote about a 5G Americas whitepaper that describes how 3GPP has standardized the 5G core in a way that lends itself for cloud based implementation. In short, that means that control plane functions are split into microservices, deployed on bare metal clusters in containers and managed with Kubernetes. So far the theory. … Continue reading The Cloud Based 5GC – From Theory To Practice

HTTP/2 in the 5G Core – How Does that Work In the Web Today?

When 3GPP set out to define the 5G core network (5GC), it used all the latest and greatest web technologies to radically reshape core network architecture. One tiny part of this is the use of HTTP/2 for signaling between functions. This made me wonder just how on the Internet today, web browsers and servers decide … Continue reading HTTP/2 in the 5G Core – How Does that Work In the Web Today?

2.5GbE Performance Revisited – Workstation Power At Home – Part 9

After the both good and bad performance of my Lenovo X250 and Ubuntu 20.04 over a 2.5GbE link to my workstation, I couldn’t just leave the topic but had to further investigate how I could potentially improve throughput when using Ubuntu’s Nautilus file manager to transfer files to and from the workstation. And again, some … Continue reading 2.5GbE Performance Revisited – Workstation Power At Home – Part 9

2.5GbE Network Performance – Workstation Power at Home – Part 8

I’m quite amazed I am already into part 8 in this series of exploring the limits of using a headless workstation as a ‘power booster’ next to my notebook. The next thing I have taken a closer look at is the connection between the notebook and the workstation, a 1 Gbit/s Ethernet link. That’s good … Continue reading 2.5GbE Network Performance – Workstation Power at Home – Part 8

5G and My Headless Workstation

It’s a bit of a strange headline perhaps but my recent blog posts on working with a headless workstation that supplies extra CPU muscle to my working setup has a lot to do with the envisaged 5G evolution of wireless networks and services. Let me explain…
