To be able to meet future challenges, SURF needs to innovate their network continuously. For that purpose, it has designed a new network architecture and will start replacing the network in various phases over the next few years. Within the new architecture, the SURF network delivers 800GE, 400GE and 100GE connectivity. Using OpenZR+ technology from Salumanus, SURF increases its backhauling capability, both in terms of bandwidth and distance.
“This new architecture gives SURF exactly what our members need: higher capacity, predictable performance, stronger security and the freedom to scale without being tied to a single vendor. It allows us to upgrade faster, operate the network more efficiently and ensure that every institution benefits from a platform that is ready for the demands of the next decade.” Said Harold Teunissen, Head of Network & Infrastructure Services, SURF
HPE Networking for backbone & border
HPE delivers the backbone and border domains of the new SURF network with PTX Series Routers (PTX10008 and PTX10002-36QDD, with Express 5 silicon’s unparalleled power efficiency), connecting SURF’s IP peering and the NetherLight global exchange point. The solution includes HPE vRR (Networks virtual Route Reflector) for simplified routing management and scalability, as well as Corero comprehensive anti-DDoS capability to safeguard research and education traffic against large-scale cyberattacks—ensuring resilient, efficient and secure connectivity for critical scientific and academic applications.
“HPE is proud to support SURF in building a resilient, high-performance network for the Netherlands’ research and education community. By delivering advanced routing, security, and data privacy solutions, we help empower local institutions to collaborate, innovate, and protect sensitive information”, commented Dobias van Ingen, EMEA CTO HPE Networking
Salumanus technology
At the heart of this transformation is the migration of SURF’s existing CWDM-based access network to DWDM (Dense Wavelength Division Multiplexing) technology. This step is crucial to enable a smooth and scalable upgrade of existing links to 100G and higher capacities, ensuring that member institutions can benefit from next-generation optical performance. In parallel, the backbone network will be upgraded to 400G and 800G using IP over DWDM technology. This approach allows SURF to deliver ultra-high-speed connectivity, eliminating the need for separate transponder hardware, minimizing power consumption and space utilisation while significantly reducing capital and operational costs.
“We are proud to support SURF in its mission to deliver world-class connectivity, our OpenZR+ technology and DWDM solutions will help build a network that is smarter, more efficient, and ready to meet the demands of the future.” Said Marcin Bala, CTO of Salumanus
Continued collaboration with Nomios
Nomios plays a key role as systems integrator in coordinating hardware purchasing and lifecycle management across suppliers and domains for the next generation of SURF network infrastructure. SURF has engaged Nomios to assist in selecting technology partners and executing the mini competition process on behalf of SURF. This collaborative model allows SURF to continuously innovate while maintaining maximum flexibility and vendor diversity.
“We’re supporting SURF in selecting the right technology mix and keeping the multi-vendor model practical across all network domains. This next step in their architecture gives the research and education community in the Netherlands the bandwidth and predictability they need for the years ahead.” Said Mohamed El Haddouchi, Managing Director Nomios
