Last summer, a huge transition was implemented under the hood of the Network Dashboard. At first glance, little seems to have changed, but especially if you click around, you will now notice that it works much faster. The major overhaul of the network dashboard had been on our wish list for a long time, because the complex authorization rules made the Network Dashboard feel like an old diesel at times (or even slower!).
The architecture of the Network Dashboard has been completely overhauled by no longer collecting all data from different systems (orchestrator/ipam/CMDB/CRM/jira) in real time, but by preparing all static data in advance in a document in the replica set. As a result, we only have to make a few very fast calls instead of 500 separate API calls. Only the traffic graphs and health status of the services are now retrieved live from the influx database.
How quickly is such a replica set updated?
The preparation of these documents in the replica set is triggered with every change to a subscription that the Workflow Orchestrator (see workfloworchestrator.org) executes on a service. The replica is also refreshed every night. This allows us to guarantee the data integrity between the orchestrator and the replica set. Only in the case of real-time changes on the network or due to self-service actions will the replica set briefly lag behind the actual state as recorded in the Workflow Orchestrator. For example, adjusting a customer alias is not immediately visible in the network dashboard, but must be processed in the replica set. Simple changes take ~4 seconds, while larger changes can take many times longer on average. At the moment we are still working on improving the automatic refresh of the pages after self-service actions, until then you will have to manually refresh a page after a change to see the latest up-to-date information.
SURFdomeinen will be available in the network dashboard early next year. Due to the complex migration of domain names and zones, this will be carried out in phases. The product manager of SURFdomeinen will communicate about this in due time.
Finally, we have introduced a new look-and-feel with a renewed landing page, on which all network services of the standard network portfolio are clearly presented in one tile.
Dutch, Nordic, and Canadian research and education networks upgrade their trans-Atlantic link to 400 Gigabits per second (Gbps) as part of the Advanced North Atlantic (ANA) consortium.
The research and education network organizations of the Netherlands, the Nordic countries and Canada have signed an agreement to upgrade the existing connection between Amsterdam and Montréal from 100 Gbps to 400 Gbps, placing it among the most powerful intercontinental connections in the world.
The Amsterdam-Montréal connection was established five years ago by SURF, the national research and education network (NREN) of the Netherlands, in collaboration with NORDUnet, the regional NREN of the five Nordic countries. With the new agreement, CANARIE – the federal partner in Canada’s NREN – joins, with the three partners contributing equally.
The Advanced North Atlantic (ANA) consortium is a joint effort of nine research and education networking organizations in North America, Europe, and Asia committed to maintaining, operating, and sharing a high-speed trans-Atlantic network infrastructure.
Partners chip in
The strength of ANA consortium lies in the contribution that each partner makes to the system, and shares this with the ANA membership to achieve a better infrastructure for all. Since all members are organizations that exist to build and operate infrastructure to accommodate the needs specific to research and education, the willingness to contribute has been high.
“This upgrade is a natural response to the increasing demand of research and education data and services exchange across the Atlantic Ocean, for example research enabled by the Large Hadron Collider (LHC) and Square Kilometer Array (SKA) instruments. The ANA consortium is an excellent example of the impact of partnerships on the collective good. This partnership enables our three national research and education networks to do more together than we can do on our own, maximizing the impact of our individual investments – both on the researchers in our home countries and the global science initiatives they collaborate in,” says Mark Wolff, Chief Technology Officer, CANARIE.
“The partners chip in when and where they can, but always with an eye to the capacity and redundancy of the entire system. This is one of the advantages of being in the research and education network community. Collaboration is smooth and trustful,” says Lars Lange Bjørn, Team Lead, Network & Service Technology, NORDUnet.
A connection landing in Canada
ANA began a little more than a decade ago as a pilot project, trying to probe interest in a 100 Gbps connection for research and education across the North Atlantic Ocean. In 2013, the first such connection was established.
Currently, 13 connections across the Atlantic Ocean are operated as a unified system by the ANA partners.
“Notably, the other 12 connections all land in the USA. Our connection is the only one landing in Canada, and this is essential for sufficient fail-over capacity and redundancy in the system,” says Harold Teunissen, Director Network and Campus at SURF.
The 400 Gbps upgrade for the Amsterdam-Montréal connection is expected to be completed by September 2025.
The Advanced North Atlantic (ANA) consortium members are KISTI, SURF, NORDUnet, NII, Indiana University, ESnet, Internet2, CANARIE, GÉANT.
NORDUnet is a collaboration between the National Research and Education Networks (NRENs) of the five Nordic countries, i.e., Denmark (DeiC), Finland (Funet/CSC), Iceland (RHnet), Norway (Sikt), and Sweden (Sunet).

For the renewal of network equipment, SURF has awarded the tender to network supplier Nomios. Through Nomios, we can purchase network equipment from different suppliers, which strengthens the innovative power of our networks. This allows us to respond more flexibly and efficiently to the network needs of educational and research institutions in the Netherlands.
With Nomios as the intermediary, we do not replace the SURF network all at once, as we did with previous generations, but gradually renew the network where the need is most urgent. This approach gives us the flexibility to choose the most appropriate network equipment and supplier per domain or network layer. This allows us to optimally match the needs and requirements of educational and research institutions. By partnering with Nomios, we are moving towards the next generation of the network, SURFnet∞ (SURFnet Infinity), which will eventually replace the current SURFnet8.
Increased bandwidth and network solutions
The new contract with Nomios applies to both the SURF fibre-optic network and the SURF data centre networks. On SURF’s national network, member institutions require more bandwidth every year. Also at the SURF data centre networks, which for instance support the national supercomputer Snellius, the demand for bandwidth is increasing. In addition, the SURF network and data centre networks are used for large international research projects, such as the Large Hadron Collider, Square Kilometer Array and the Einstein Telescope, which not only demand a lot of bandwidth but also place specific demands on the network.
Benefits of flexible development
The flexible development of our network offers tangible benefits to all member institutions:
Optimal use of existing resources: by replacing equipment in phases, we extend the lifespan of our current infrastructure.
Better adaptation to change: we can respond faster to unexpected challenges and technological developments from suppliers.
Direct access to innovation: we can acquire new and innovative technologies quicker and apply them to the SURF networks.
User-friendly optimisation: with the diversity of network equipment available, we can optimise the network based on the broad requirements of education and research institutions.
Think about SURFnet Infinity
In the coming months we will work with our partners and members to further develop SURFnet∞ (SURFnet Infinity), the new generation of the SURF network. During the knowledge session Procurement, architecture and design SURFnet Infinity on the 21st of November, we will present the first draft version of the network. We invite all stakeholders to think along and participate.

SURF, the collaborative organisation for IT in Dutch education and research, continues to push the boundaries of optical communication.
In a strategic partnership with Ribbon, SURF successfully achieved 800G over an existing 1,650 km fibre-optic link. This link connects renowned research institutes, including Nikhef, to the Large Hadron Collider on the CERN campus in Geneva, marking a significant milestone in optical communication.
The trial demonstrated several of Ribbon’s advanced transport solutions:
Apollo TM800_2, using 5nm-140Gbaud transmission technology, optimises capacity and reach for 800G transport.
Apollo Open Optical Line Systems, including hybrid EDFA-Raman amplifiers, maximise the capacity of SURF’s existing G655 and G652 fibres and successfully carry third-party vendor wavelengths.
NPT 2400 metro router, interoperable with SURF’s network, delivers 2x400GbE uplinks running EVPN services over BGP to 8x100G ports within the network.
Harold Teunissen, Director of Network and Campus at SURF, stated that the trial with Ribbon “pushes the boundaries of our current fibre and demonstrates what is technically possible with Ribbon’s equipment.”
He added that it “marks a crucial step forward as we prepare our network to meet the future needs of scientific research and education in the Netherlands and beyond.”
In collaboration with Nokia, Nikhef, and CERN, SURF successfully tested the data transmission speed between CERN in Geneva and Amsterdam. The test achieved an impressive speed of 800Gbps over the 1648-kilometre fibre-optic link. This confirms the network’s readiness to handle future large-scale data flows, such as those generated by CERN’s particle accelerator.
Upgrade of the Large Hadron Collider The test was conducted in preparation for the planned upgrade of CERN’s Large Hadron Collider in 2029. This upgrade will enable more precise measurements, facilitating detailed research into the origins of the universe. The upgrade is expected to result in five to seven and a half times more research data than currently produced. All this data will need to be distributed to universities and research groups worldwide, including those in the Netherlands, via networks such as SURF’s.
To successfully transport this immense volume of data, SURF has optimised its optical network. Nokia tested its latest-generation network cards to evaluate their performance over the SURF network under such demanding conditions. The successful test demonstrated that this section of SURF’s network between Amsterdam and Geneva can handle significantly higher capacities than previously anticipated.
Increasing Demand for Bandwidth and Network Speed The upgrade of the Large Hadron Collider aligns with the global trend of data-intensive research requiring higher network speeds, increased bandwidth, and greater storage capacity. Research projects such as the Square Kilometre Array, the Einstein Telescope, the Low-Frequency Array, and the International Thermonuclear Experimental Reactor also generate massive data streams, demanding speeds beyond the current 100Gbps and 400Gbps standards.
Insights and Follow-Up Tests Testing an operational network connection over long distances using real data from the Large Hadron Collider provides unique insights into data transport and storage at scale. These types of tests, regularly conducted by SURF in collaboration with various network partners, are essential for enhancing infrastructure to support data-intensive research.
SURF continues to innovate by testing, optimising, and expanding its network, global network hubs, storage capacity, and computational power. The goal is to ensure that data-intensive research can be conducted effectively now and in the future.
