88 people from nine different countries and territories met in Manchester at UKNOF48 on Thursday, 18 November and Friday, 19 November 2021. They were joined by well over 200 people who watched the free live stream and engaged with industry colleagues using our Mattermost server.

This was our first in-person event in 21 months and our first ever hybrid event, with a mix of live speakers in Manchester and others joining over the Internet.

10 speakers presented on a variety of Internet operations topics.

On the first day, they included virtual lab environments, ripe-554bis, the evolution of the network engineer, helping networks who are starting to peer, a new way to deploy multicast for content distribution, and the difference between organisations that are built around work from anywhere and those forced into it.

On the second day, they included building automation for 5G networks in Orkney, developments in Internet governance, handling DDoS attacks originating from IXPs, and performance monitoring.

We also programmed seven hours of breaks over the two days so that participants could catch up with industry colleagues and friends.

Recordings of the talks from UKNOF48 have been published and are linked below, so you can review the details of talks you enjoyed or catch up on a talk you missed.

Highlights – Day 1

The opening talk came from Ondřej Caletka who described the RIPE NCC’s Virtual IPv6 Security Lab Environment.

He was followed by Sander Steffann who gave the history of the RIPE community’s document on what to specify when buying network equipment that needs to support IPv6, ripe-554bis and the recent work to update it after more than a decade.

After the break, Elena Sanchez and Jose Leitao talked about the career growth of network engineers at Meta (formerly Facebook).

They were followed by Rebecca Class-Peter who spoke about everyone’s challenges when working with networks who are transitioning from buying transit to peering, and how the Euro- IX community’s Peering Toolbox project can help everyone succeed.

Lenny Giuliano energised everyone with a talk that described a new way to deploy multicast over unicast to deliver content at scale while lowering costs.

Then, Cathy Almond rounded off the day with a talk that looked at some of the new challenges associated with working from home or anywhere, now that the technology has been thoroughly tested.

Highlights – Day 2

Marek Isalski kicked the day off with a talk describing the travel, weather, and configuration challenges associated with building a 5G network for Orkney.

He was followed by Chris Buckridge, who told us about the changing regulatory environment for the Internet and how its governance is being discussed at national and international level around the world.

After the break, Pavel Odintsov described how customers can handle DDoS attacks originating at IXPs.

After another short break, Szymon Trocha introduced the perfSONAR project and explained how its modular architecture can be used by networks to manage performance.
