Nokia and Deutsche Telekom Group announced they are expanding their strategic cooperation to build a 5G-ready IP network. Deutsche Telekom has selected Nokia’s 7750 Service Router (SR) platform to significantly expand capacity across its edge/core routing network as it prepares for next-generation broadband and 5G services.

Deployment has already started in Greece, where Nokia is replacing and modernising the operator’s existing IP network. Rollout in Hungary is expected in Q4 2020. With networks experiencing unprecedented traffic growth and unpredictable demands, operators want to meet ever-increasing performance requirements while driving down network costs.

The scale, feature breadth and versatility of the Nokia 7750 SR-s platform addresses these requirements, enabling operators like Deutsche Telekom Group and its affiliates to build bigger, smarter, automated and secure networks with greater return on investment.

As part of its network modernisation, Deutsche Telekom needed to replace an existing IP edge/core network that was reaching its end of service with a new network that can cope with 5G and ultra broadband access requirements. A key principle to achieve this was the consolidation of network layers through the integration of IP aggregation and edge/BNG (Broadband Network Gateway) functions into one converged layer.

Deutsche Telekom selected the Nokia 7750 SR-7s routers as they support the full spectrum of provider edge, gateway and core functions for advanced residential, mobile and enterprise services. Powered by the programmable FP4 network processing silicon, the routers will enable Deutsche Telekom to boost IP network capacity with deterministic performace for a top-quality subscriber experience.

As a result, Deutsche Telekom can support 5G interconnectivity and an increasing growth in backbone traffic driven by an increase in mobility applications, video streaming, gaming and other high-capacity demands such as remote working.

The 7750 SR-s is managed by the Nokia Network Services Platform (NSP). NSP supports 5G IP transport with automated slicing across IP and optical transport layers with end-to-end orchestration of network resource provisioning and assurance operations. This simplifies operations so that operators can create customer policies/slices with different network performance, quality and routing capabilities to respond quickly to fast-changing subscriber demand.

Bernhard Scholl, technology europe VP access core & transport at Deutsche Telekom, says, “Deutsche Telekom Group affiliates need to expand and modernise their IP networks to address stringent 5G IP transport requirements. We continue to see tremendous growth in network traffic and the need to deliver more throughput and higher capacity with strict QoS to our customers is critical.

This is particlarly the case as bandwidth intensive applications are shifting to on demand video along with the growing usage of cloud-based services. Building out this backbone with Nokia’s IP edge routers will allow us to stay ahead of our customers’ network needs.”

Vassilis Kazatzopoulos, head of international sales DT Global customer business team at Nokia, says, “With trends like 5G, IoT and Industry 4.0 now a reality, networks are expected to handle hundreds of new applications and services for millions of users.

The Nokia 7750 SR-s series of IP routers takes router performance to the next level by delivering the massive scale, comprehensive feature set and platform versatility needed to stay ahead of evolving demands. Nokia is excited to expand its longstanding relationship with Deutsche Telekom Group to help prepare its affiliates’ networks for the future.”
