Energy optimisation in GÉANT - Tony Barber, GÉANT

All the clues on how the GÉANT team is optimising energy consumption for the network and the services offered on top of it.

Energy optimisation and green solutions - Ariel Oleksiak, PSNC

In this presentation, we will see the energy optimisation in the computing and networking areas at PSNC, including implementation and works which PSNC is doing for external parties.

Flash talks

• Surviving Power Outages - Simon Leinen, SWITCH

Switch have been researching on how the network could survive power  shortages/rolling blackouts this winter.

• Measuring the Kilowatt per port - Sebastian Neuner, Belwü

Belwü, together with researchers at Osnabrück University and Deutsche Telekom is doing measurements in their lab to answer questions like "How much power does an idling port use?", "How much power goes into forwarding the packets?" or "Can power be saved by disabling ports at night?".

Telemetry in RNP - Guilherme Ladvocat, RNP (remote)

The RNP (Brazilian NREN) Network Operations team have been working with Telemetry since 2019. The benefits of implementing this technology proved that it is more reliable and scalable compared to the SNMP protocol. Since then, we have been working to move from the legacy protocol to the new one, but as early adopters, we encountered limitations and issues in the way. So in the talk, we would like to share our path/experience to implement telemetry in our network and what we are still working on.

P4-based flow monitoring system - Pavle Vuletić, University of Belgrade

P4 became a popular buzzword in networking community several years ago, because network device programability enables new applications, autonomic networking and network operations, in-band network telemetry and other new network features. However, are the NRENs ready for such a shift, or they will continue to procure complete solutions? What does it take to develop a P4-based application? What are the skill gaps NRENs might be facing? In this talk we will share our experience from developing a network flow monitoring system capable of capturing unsampled network flows at 10G that leverages P4 capabilities of Netronome NICs. We will describe the system and the results we got, but also share a series of challenges we faced during the development. 

RARE and the Global P4 Lab - Frederic Loui, RENATER

Presentation about the development of RARE (Router for Academia, Research & Education), free, open and cost-effective routing solution used in several regional networks and an IXP in France, as well as in other institutions around Europe.

Efficient energy management for servers in data centers 

Gabriel Verdejo Álvarez, rdlab UPC

A holistic approach to the server energy consumption issue in IT facilities, using a three layer strategy (architecture, service and physical) in order to deal with energy restrictions at any level. We will share our experience at /rdlab UPC (Universitat Politècnica de Catalunya)

DDoS detection and mitigation - Jonny Lundin, SUNET

SUNET has analysed several options to work in DDoS detection from different angles. Find all the details in this presentation.

NaWas anti-DDoS - Frank Dupker NBIP/NaWas

NaWas offers an on-demand service to combat DDoS attacks to small, medium and large Internet and VoIP providers in the Netherlands and the rest of Europe. This helps to avoid large investments and access more powerful weapons to fend off DDoS attacks.

NeMo DDoS software - Alf Moens, GÉANT 

The NeMo-DDoS software is a powerful tool for Netflow-based DDoS and traffic anomaly detection & analysis. It was originally developed to address NREN-specific network analysis needs and has been enhanced ever since. 

URAN Research and Academic network - Yevhenii Preobrazhenskyi, URAN (remote)

Summary of the challenges faced to keep the network running in the face of hostile aggression.

Sharing results on Quantum Key Distribution tests performed in the GÉANT lab, investigating data and quantum key waves multiplexed on a shared fibre.

Flash talks

• Update on JANET network - David Richardson, Jisc
  

The "classic" SIG-NOC NOC/Network update of the Jisc network.

• OAV Maturity Model - Maria Isabel Gandia, CSUC

GÉANT has created a questionnaire to self-asses the level of maturity of each R&E insitution regarding orchestration, automation and virtualisation.

Update on the GÉANT network - Tony Barber, GÉANT

An update on the progress made to date in the GN4-3N refresh project. Updates will include deployment status, migration status and decommissioning status along with a look at the top risks, financial status and what is planned for the next months.
