2nd Telemetry and Data Workshop

This workshop will target the way the monitoring data is collected and how to share the data:

1. The first part will be related to telemetry and traditional vs streaming telemetry;
2. The second part will present data plane programming telemetry (P4);
3. The last part of this workshop will focus on how to share monitoring data between organisations in the research and education community. Read more...

GÉANT Infoshare: White Box in NREN context

This infoshare will present the results of white box subtask within Network Technologies and Services Development work package of GN4-3. This subtask aimed to validate whether the white box solutions available on the market can be useful in an NREN context.

The strategy, defined in detail in [D6.3], is based on potential NREN use cases for which the white box solution is validated and then put into production if the outcome is acceptable to the NREN. Read more...

24th STF (Service & Technology Forum) Meeting

A meeting of NREN Access Port Managers (APMs). The primary purpose of the Services and Technology Forum (STF) is to provide the NREN APMs with the relevant GÉANT service and network information for dissemination within their respective NRENs so as to ensure each NREN is constantly updated with changes to those services that are of importance to a particular NREN. T. Chown, X. Jeannin and R. Lapacz presented updates on WP6 serices and development.Read more...

Quantum Key Distribution Simulation

Quantum Key Distribution is a technology at an early stage. A QKD link requires optical connection between the network nodes. For now, there are not many quantum hardware suppliers and the hardware available is very expensive. Network simulation appears a good solution to validate the different elements that made up a QKD service (network algorithm or protocol), to save a lot of money and time in creating a testbed and to start becoming familiar with this technology. The simulators are different levels of simulation (optical layer, the key distribution service, ...). Read more...

Orchestration, Automation and Virtualisation: Focusing on the user

A successful digital transformation entails flexibility, efficiency, and self-service provisioning. In other words, a user-centric approach, which implies the usage of Orchestration, Automation and Virtualisation techniques (OAV). The OAV team in GN4-3 created several resources to help the NRENs in their journey to this digital transformation through OAV (Training, Wiki, Terminology, Blueprint, Mapping of Architectures for NRENs..) The goal of this session is to gather ideas for future work, presenting the existing resources together with use cases from the NRENs. The BoF is an opportunity for NRENs to come together to agree on common actions. Read more...

European Time and Frequency Services - Principles, Challenges and Use Cases

"Time & Frequency (T&F)" transport as an optical service has become a hot topic for the past ten years, mainly boosted by a dramatic improvement in performance. National Metrology Institutes (NMIs) in collaboration with NRENs have demonstrated three orders of magnitude higher stability of time and frequency services than any existing commercial service over distances of at least 1,500 km, offering tremendous potential for new services in a wide range of scientific, societal and economic domains.

Data Transfer Nodes: How Fast can your Data Travel?

Some research projects need to move huge amounts of data. Using a desktop computer and the regular network to do it may not be the right option to get the best performance. Setting up a DTN node is not always straightforward: there are different types of software, some parameters need to be tuned in the servers, distances reduce the performance in TCP. Read more...

Measuring WiFi and eduroam Network Performance with WiFiMon

WiFiMon, a WiFi network monitoring and performance verification system, is a new GÉANT service. It is capable of detecting performance issues, visualising the workload of the network, and providing technical information about the WiFi network (e.g. signal strength, link quality, bit rate, etc.). WiFiMon leverages well-known performance verification tools like Akamai Boomerang and Speedtest/Libretest and in addition uses data from the WiFi physical layer in order to gather a comprehensive set of WiFi network performance metrics. It combines crowdsourced measurements and measurement data obtained from small form hardware probes. Read more...
