14:30 Software Best Practices for Networkers

It's 2023 so everything is automated in our network's because we're all so cool, we're all even using Python and Go instead of BASH and expect, but beyond simply writing code, do you know when to implicitly model your infrastructure vs explicitly model it? You have network design standards, but do you have coding and contributing standards too? What would they look like? Are you checking whether you're compromising supportability for ease of development?

I'm currently working on the deployment of a greenfield network and greenfield automation stack, in a group of people who range from "hardcore networkers with minimal coding skills" to "hardcore developers with minimal networking skills". Along the way we have all learned many lessons, some were lessons regarding coding, some were lessons regarding collaboration, some were lessons regarding automation strategies.

In this talk I will share some general lessons learned and considerations we've had to make, with the community, which most people should be able to relate to, in the new age of "automated everything".

16:00 Things to consider with 400G over DWDM

The 400G market is growing with many more organisations looking to deploy 400G transceivers for IP over DWDM.
One thing to consider with 400G optics is that some use a slightly broader passband which can create problems when used with a standard 100Hz-based DWDM system.
This lightning talk is aimed at highlighting the issue and providing options on how to overcome this when using passive DWDM systems

The UKNOF Programme and Communications Committees (PC and CC) are both looking to recruit new volunteers.
Dave Wilson has recently joined the Programme Committee, and Steve Karmeinsky has recently stepped up as the new Chair of the Comunications Committee.

In this lightning talk, they will outline the roles they have stepped into, and give some insight into how the sausage is made behind the scenes at UKNOF, in the hopes that some of our audience may be interested in joining us.

10:00 5G Security

Here is the abstract of our presentation:

The landscape of the 5G network is continuously evolving, raising an increasing number of security threats at different levels and applications. With the advent of 5G technology, the need for robust security measures has become more important than ever. 5G network is no longer a technology for making calls and data browsing over the phone alone; rather, it has become an enabler for a connected world with advanced use cases for almost every industry, such as manufacturing, public safety, healthcare, public transport, energy, and utility, automotive, media, and entertainment. With the advanced and critical use cases, it becomes imperative to secure the network and prevent any misuse. In this paper, the focus is to present a comprehensive approach to securing the 5G network by identifying the threat landscape and possible attack surfaces and a structured approach to continuously protecting and securing them with approaches like defense-in-depth and zero trust.

Speakers: Kamal Singh, Mr Rohit Saxena

10:30 Weaponizing mobile infrastructure: Are politically motivated cyber attacks a threat to democracy?

In this engagement, we describe our intelligence gathered around Russian and Ukraine conflict. How mobile networks were weaponized to inflict cyber war with primary focus on nation state activity led by Russian source/identity holding various objectives.
i.e performing account takeover, attacks on Ukrainian subscribers via SS7 Spoofing and new threat indicators captured being used by Russian sources.
The massive hybrid war resulted in regulators revisiting their cyber resilience to handle these sophisticated attacks towards mobile operators or attacks initiated covertly by operators.

11:30 BGP Security - Hijack and Route Leak Detection

In this presentation, we focus on BGP security using the Code BGP platform. We start with an introduction to the various types of BGP hijacks and route leaks and the challenges related to detecting BGP anomalies. We explain how the Code BGP Platform leverages multiple data sources and GraphQL subscriptions to detect BGP events of interest. We present two exact prefix hijack events against root DNS prefixes that took place a few months ago. Finally, we do a demo of configuring alert rules, doing actual announcements on the Internet and detecting hijacks.

12:00 Tips and tricks, lessons learned from the network service provider operating at the times of long-term crisis

Internet was built on principles of redundancy and is used to mitigate disruptions. But what happens when there are multiple problems or damages, that need to be managed simultaneously? Are you ready to operate under the circumstances of blackouts, lack of diesel, curfew, and critical equipment shortage, when all these factors coincided? What about events of natural force that we’ve recently witnessed in Turkey and Syria, do you have disaster recovery plans at hand?
Many businesses were affected by the Russian war in Ukraine – some had to change how they operate, and others had to also deal with securing the network under the fire. The price of being unprepared to function in the event of a crisis of this scale is too high.

Our team has a unique experience of dealing with the constantly multiplied network and operational damages within the last full year. You’ll hear a review of the backbone operator’s operational and tech experience, affected by the war.

We’ll share the learnings of overcoming multi-layer challenges under the most extreme circumstances.

We’ll speak of how RETN minimizes the impact of disruptions, reduces the risk of financial losses due to outages, and keeps ensuring the continuity of the services.

14:45 Network Log Aggregation with Loki

Loki is an open source, horizontally-scalable log aggregation system inspired by Prometheus. It takes a different approach to many other log aggregation solutions by avoiding indexing on log content and instead having powerful query-time operations.

In this talk I'll give a a short overview of loki, how we've integrated it with our network and the powerful capabilities it enables.

15:30 On the Temporal Behaviour of a Large-Scale Microservice Architecture

Microservices are fast becoming the predominant architectural style for orchestrating online services due to the advantages they can bestow over monolithic systems. However, as microservice architectures grow in size they quickly become complicated to understand and manage. Their characteristics raise the question as to whether they may behave like complex systems. In this work, we use tools from graph theory to analyse the static and temporal dependency structure of a large-scale microservice architecture. We find that the dependency structure can fluctuate significantly at run time and further, that it can be clustered into distinct and persistent states with recognisable characteristics. Importantly, we show that these states can have functional implications for the performance of the microservice architecture. These early findings suggest that microservices may indeed behave like complex systems and, as such, would benefit from complex systems thinking when approaching their management and development.

16:25 The Integration of Terrestrial and Space Based Communications

For many years space-based satellites have provided an essential means of connectivity for a wide range of telecommunications requirements. Today we are living through the era of “New Space” in which satellites are being launched into low earth orbits to form mega-constellations which promise broadband access and lower latency than traditional satellite services. This, coupled with other developments in non-terrestrial networks, such as drones and high-altitude platforms, means we must fundamentally rethink how we evolve fixed and mobile telecommunications networks to deliver services which benefit from the integration of terrestrial and space-based communications. These benefits include greater geographical reach and enhanced availability. This talk will review current use cases, explore recent developments in industry and standards organisations such as 3GPP, and set a vision for the future of mission critical communications across a wide range of sectors.
