GÉANT will deploy Infinera’s programmable and open packet optical SDN solution on its pan-European network, which interconnects Europe’s National Research and Education Networks (NRENs) and supports over 50 million users at 10,000 institutions across the continent.
Infinera said GÉANT has tested and validated two key components of its packet optical SDN solution, the Open Transport Switch (OTS) software and the Packet Switching Module (PXM). The PXM enables Ethernet and MPLS switching intelligence on the Infinera DTN-X platform, which is widely deployed in the GÉANT network.
Infinera’s DTN-X family delivers terabit-class scalability, operational simplicity and efficiency, and high levels of flexibility and programmability for multi-layer Intelligent Transport Networks. Infinera’s OTS software further enables multi-layer SDN programmability of Infinera networks with an open modular architecture, open APIs and a simplified programming model for rapid SDN application development. Introduced in 2015 and initially deployed for SDN-driven optical bandwidth on demand services, OTS has been extended to support programmability of Layer 2 packet services via the PXM, enabling multi-layer service provisioning and optimization over an integrated packet-optical transport network.
GÉANT validated the Infinera packet SDN solution components and is working with ON Lab to develop the ONOS SDN controller to create an SDN-driven approach to network optimization. Once the solution is fully deployed, GÉANT will be able to enhance how large data flows across the network are routed, optimizing connectivity and capacity between the IP/MPLS and optical layers to deliver a multi-layer transport solution in the support of data-intensive research computing projects. This will improve the service offered to users and reduce the need to overprovision capacity at the IP/MPLS and optical layers. GÉANT has modeled the benefits of re-architecting its network to use the Infinera packet optical SDN solution versus multiple alternatives. This solution avoids 50 percent of expenditure across the network where it is to be initially deployed.
“Infinera’s packet optical SDN solution offers an effective approach to optimize the GÉANT network and efficiently and optimally handle large traffic flows,” said Mark Johnston, Chief Network Operations Officer at GÉANT. “We look forward to realizing the expected efficiencies and operational benefits of this solution, and continuing our excellent collaborative work with Infinera on future SDN applications.”
“We are delighted to work with GÉANT to deliver real-world, deployable SDN solutions that create tangible value,” said Nick Walden, Senior Vice President, EMEA at Infinera. “This is just one example illustrating the strong partnership between our organizations, and we are excited about working with GÉANT to deliver future innovations.”
GÉANT Deploys Infinera Cloud Xpress with 100 GbE for DCI
GÉANT, Europe’s leading collaboration on e-infrastructure and services for research and education (R&E), and operator of the pan-European R&E network that interconnects Europe’s National Research and Education Networks (NRENs), has deployed the Infinera Cloud Xpress to extend their 100 gigabit Ethernet (GbE) network connectivity into data centers. Initial connectivity is being provided to Jisc, the UK organization for education and research…
Europe’s GEANT Deploys ONOS
GEANT, the European research network formed last year through the integration of the TERENA and DANTE initiatives, has deployed the Open source SDN Network Operating System (ONOS) on its pan-European testbed network. The ONOS installation allows researchers to define, build, test and rebuild highly scalable, high capacity virtual networks quickly, easily and cost-effectively. Specifically, GEANT is running a new Inter Cluster ONOS Network Application…

Five Latin American research and education networks (RENs) – Academic Network at Sao Paulo (ANSP), Brazilian National Research and Education Network (RNP), Latin American Advanced Networks Cooperation (RedClara), National University…
DANTE and Infinera Set Optical Record: 8 Tbs Super-Channel Capacity
Infinera and DANTE (Delivery of Advanced Network Technology to Europe), have set a Guinness World Record for the fastest rate of multi-Terabit optical capacity provisioning across the GÉANT Network. Infinera and DANTE were able to install and activate eight Terabits per second (Tbps) of long haul super-channel optical capacity. The record was set using an Infinera Intelligent Transport Network, featuring the DTN-X packet optical transport networking…
