        WDM Basics 30m

        WDM has been around for many years and is a fundamental, yet often overlooked area of networks. As new people enter the industry, who perhaps don't work with Layer1 technologies regularly, they might appreciate an introduction to WDM.
        The aim of the presentation is to look at what WDM is (and isn't), with a brief overview of amplification, muxponding & transponding, with an introduction to modulation, dispersion & attenuation & how this affects higher speed services.

        Network Source of Truth and Data-Driven Network Automation with Nautobot 30m

        Introduction:

        Imagine a network that runs like a well-oiled machine - efficient, reliable, and as secure as Fort Knox. But here's the catch: it takes sharp-eyed administrators to spot and fix configuration blunders before they turn into catastrophic failures or sneaky breaches. The trouble is, modern networks are so vast and intricate that deviations from configuration standards often go unnoticed for months or years, leading to headaches like sluggish performance, surprise blackouts, and dreaded security breaches.

        But fear not, for there's a hero in town - the data-driven configuration compliance engine! This wonder tool ensures that your network always stays true to its intended configuration.

        Unlike those old-fashioned rule-driven approaches, it is imperative to attack it with a data-driven and data-first approach, integrated with the Network Source of Truth.

        With the power of Nautobot's stored data, this open-source Configuration Compliance solution works its magic, automatically maintaining configurations across networks of any size and complexity ensuring that your network is always configured as it’s intended to be.

        Say goodbye to chaos and hello to a network that's always on its A-game.

        Ready to level up your NetDevOps skills?

        Join us in this webinar and discover how the Nautobot Configuration Compliance solution fits perfectly into your organization, bringing you closer to network nirvana. Don't miss out - it's time to unleash the magic!"

        What's Happening in Optical Networks? The Evolution of Coherent Pluggable Optics 30m

        Optical networks are undergoing rapid evolution and have advanced considerably over the last 2-3 years. This presentation will update the audience on the latest trends within the industry with a focus on innovation within pluggable optics that are driving the resurgence in interest in IPoDWDM architectures and the drive towards Open Optical Networks. Of course "A tool is ever only as good as your ability to use it" so we'll pay particular attention to how these trends impact the management of the combined IP and Optical environment.

        Volcanic Hazards and Subsea Cables: Lessons from the 2022 Eruption of Hunga Volcano 30m

        The January 2022 eruption of Hunga Volcano (also known as Hunga Tonga-Hunga Ha’apai), in The Kingdom of Tonga, was the most explosive volcanic event recorded by modern instrumentation. The eruption sent shockwaves multiple times around the world, generated devastating tsunamis that damaged coastal communities and infrastructure and severed the domestic and international subsea cables that connect the islands of Tonga to the rest of the world at a time critical for disaster response. While geological hazards only account for <15% of subsea cable faults globally, where they occur, they can be particularly challenging to repair as they can affect very large areas of seafloor and damage multiple cable systems synchronously. Island nations, like Tonga, have fewer cable connections and therefore are more prone to major disruption in the event of subsea cable damage, and those that lie close to regions that experience geological events or extreme weather are particularly vulnerable. Two subsea cables connect to Tongatapu (the main island of Tonga), an international cable that runs towards the west and a domestic cable that runs north connecting island groups. Both of these cables were damaged during the 15th January eruption.

        This event was exceptional not only because of the size of the eruption, but also because of the availability of high-resolution bathymetric data of the edifice before the eruption and the acquisition of a comparable dataset by a fast-response scientific expedition just four months after the eruption, which reveal the profound impact the volcanic eruption had on the seafloor. These data show that soon after the initial explosion the eruption column began to collapse directly into the ocean. The delivery of large quantities of volcanic rocks, ash and gas vertically into the water and then onto the steep (45) slopes of the volcano generated extremely fast moving, long run-out flows that were responsible for the damage to the cables. Flow pathways were strongly controlled by the pre-existing topography, exploiting and deepening (sometimes by more than 100 m) pre-existing chutes on the volcano flanks, three of which funnelled flows directly towards the domestic cable, 15 km away from the eruption vent. Topographic steering continued to be important away from the volcano, deflecting flows to the north and south along the domestic cable and directing flows around the south of the volcano towards the international cable. As the flow transitioned to lower gradients (i.e. within the valley where the domestic cable lies), it deposited up to 22 m of volcanic material on top of the cables. Based on the time between the collapse of the eruptive column and the damage to the domestic cable and the identified flow pathways, we calculate an averaged velocity of 68 - 122 km/hour for these flows; the fastest velocity documented for any underwater density current.

        While such events may be rare, there have historically been a few cable faults related to volcanic activity, which often affected volcanic islands in the Pacific and the Caribbean. This number is low primarily because of careful route planning, which has managed to avoid many of the hazards associated with these regions. However, as subsea telecommunications networks expand and there is a socioeconomic push to connect these areas, associated hazards cannot necessarily be fully avoided in future. Enhanced seafloor mapping and improved volcanic monitoring is required to improve our understanding of volcanic activity and associated hazards, while increased diversity of routes and landing points, backup stocks of cable for repairs, and complementary communication systems will increase resilience.

        Measuring Carbon: IRISCAST and UKRI NetZero DRI 30m

        As the UK’s journey towards NetZero accelerates, we need robust information to inform funding decisions, policy development, hardware procurement, and operational level job scheduling.

        The IRISCAST project set out to use a learning-by-doing approach to conduct a proof-of-concept carbon audit across a multi-site heterogeneous research infrastructure by collecting and analysing 24-hour snapshots of actual usage across different facilities within the IRIS community [1]. By developing a carbon model and combining usage data with embodied carbon costs of the hardware and infrastructure we were able to make estimates of our carbon costs, identify the key elements that contribute to it, and the important metrics needed to measure it [2].

        IRISCAST was funded by the UKRI Digital Research Infrastructure NetZero Scoping Project which has now published its technical report and recommendations [3].

        We present our key IRISCAST findings, recommendations, and lessons learned, in the context of the UKRI Net Zero DRI Scoping Project final technical report.

        Network Automation at an Internet Exchange Point 30m

        LONAP is a not-for-profit, neutral Internet Exchange Point established in 1997 and based in London. With around 250 members, over 350 connected ports across 8 points of presence and peaks of 1Tbps (or 130Mpps) of traffic. We operate with 4 full time staff so rely on automation to be able to grow in members, ports and traffic year on year, while reducing our pricing. This presentation will give an introduction to us, our network and our tooling.

        This panel session aims to share perspectives on the user’s right to privacy and security within the context of the network operator. We consider the technical aspects of this, such as TLS-ECH and BGPsec, as well as governmental policies and the role of regulation, engagement with Internet standards, and the position of network operators within this space: what their role is, what it can be, and how operators can inform policies, regulations and standards. We hope to have a discussion with representatives from academia and research, alongside network operators and policymakers.
