Covering Disruptive Technology Powering Business in The Digital Age

Nokia has expanded its industry-leading IP router portfolio with the introduction of the new 7730 Service Interconnect Router (SXR) product family.

The new platforms bring the service router performance, security, assurance and sustainability customers rely on from Nokia at the IP edge and core into advanced IP access and aggregation networks. The scale and capabilities of the new platforms also make them ideal for smaller/distributed IP edge locations, addressing the increased capacity and capability demands driven by broadband investments and evolving cloud network architectures.

All 7730 SXR systems are powered by Nokia FPcx routing silicon, a new line of in-house designed, fully programmable network processors that bring the value of Nokia’s high-performance and feature-rich FP silicon into a compact and extensible package optimised for next-generation IP access, aggregation, and edge applications. The 7730 SXR family is also enabled by SR Linux, Nokia’s open, resilient, and extensible network operating system (NOS).

Changing with Evolving Network Architectures

Today’s networks are widely recognised as critical infrastructure; however, network architectures are changing. Acceleration of broadband access deployments, including fixed, fixed-wireless access, and 5G, are driving the need for more capacity and intelligence deeper into aggregation and metro networks. With applications evolving to cloud-native approaches and the adoption of edge clouds, networks need to become more agile and cloud-like. In addition, the significant proliferation of end devices is contributing to an increased attack surface and security threats.

Current IP access and aggregation routers are typically optimised for simple IP transport applications. At the same time, evolving network architectures result in frequent churn in these networks to meet the needs of new protocols and services, driving up network Capex and Opex costs. The call of the day is to provide secure and assured connectivity on a platform that fully leverages modern network operations, and has the silicon and software flexibility to easily adapt to new requirements. This requires a new approach to IP routing in this domain of the network.

The Nokia 7730 SXR family addresses these requirements by delivering efficiency and flexibility, powered by a unique combination of a next generation chip architecture and a forward-looking NOS. Secure connectivity is enabled via platform support for MACsec, ANYsec and DDoS mitigation with traffic inspection.

Assured IP services are enabled through FPcx’s deterministic performance, advanced QoS capabilities and innovative approach to enabling in-service software upgrades. Power efficiency and reduced TCO is realised through right-sized capacity and interface speeds, support for more efficient network designs, and a system built from the ground up for automation at scale in a modern NetOps environment. Flexibility is enabled by FPcx as a fully programmable NPU combined with the cloud-native architecture and extensibility of SR Linux.

Solution Specifics

• New 7730 SXR family of routers provide capacity, interface speeds and form factors that are optimised for IP access, aggregation and smaller/distributed edge locations.
• New Nokia FPcx silicon, custom designed for service provider and mission-critical IP networks. FPcx is fully programmable, offers true deep buffering and rich telemetry, optimised for the delivery of secure and assured services with the right speeds at the right economics.
• Nokia SR Linux NOS, a unique network operating system that blends the best of Nokia’s proven and hardened IP routing protocols and services in a cloud-native software architecture designed for automation and extensibility.

Thomas King, CTO at DE-CIX, said about Nokia’s expansion: “For over a decade, Nokia has been providing DE-CIX industry-leading IP hardware and customised silicon, continually pushing the boundaries of innovation. We are excited that they continue to invest and innovate in routing technologies that help operators like DE-CIX deliver not only high-performance IP services, but also secure and assured IP connectivity services our customers demand.”
