This will allow data center and cloud providers to scale and adapt operations to the exponential year-over-year growth in traffic and the constant change brought about by technological shifts such as 5G and Industry 4.0. The new Nokia Service Router Linux® (SR Linux) NOS and Nokia Fabric Service Platform (FSP) were developed in conjunction with leading global web-scale companies, including Apple, which is deploying the technology in its data centers.

Network operating systems have not kept up with demand. Although they evolve, traditional systems are restrictive and difficult to customize, integrate, and automate. For example, current leading systems expose limited functionality for customization and even require cumbersome integrations. Often, this means rudimentary applications that need to be recompiled every time the NOS vendor releases updates. New attempts at open systems are nascent, challenging to operationalize, and generally unproven at scale.

Nokia SR Linux is a true breakthrough, being the first modern microservices-based NOS, and the SR Linux NDK (NetOps Development Kit) exposes a comprehensive and rich set of programming capabilities. Applications are easily integrated through modern tools like gRPC (Remote Procedure Call) and protobuf, without recompilation, language limitations, or dependencies. SR Linux also inherits Nokia's proven Internet protocols from the Service Router Operating System (SROS), the hallmark of Nokia's massive installed base of carrier-grade routers. SR Linux is, in effect, the industry's first open and flexible network application development environment.

Nokia FSP provides the toolset that cloud builders need to implement policy-based and intent-driven network operation. More than just a node-centric management system, FSP was designed to build, deploy, and monitor the entire data center network with powerful network-level constructs. Finally, FSP includes technologies previously available only to the largest cloud builders, such as a virtual digital twin with real-time health correction for validation and troubleshooting.

Nokia Solution Product Details:
• Nokia SR Linux is built on the proven Nokia SROS Internet protocol suite, a robust foundation with proven scalability, resilience, and interoperability that has been deployed globally on over one million routers across IP networks and the Internet. Hardware-agnostic and running on standard Linux, it implements a core architecture around model-based management, fine-grained telemetry streaming, and modern interfaces such as gRPC and protobuf, providing easier programmability with greater visibility and deeper control for all applications. It offers a state-of-the-art NDK for customers' NetOps teams to develop new applications and operational tools in their preferred language.
• Nokia FSP is a suite of declarative intent-based automation and operations tools that delivers agile and scalable network operations for SR Linux and multi-vendor data center infrastructure. The Nokia FSP integrates seamlessly with existing operating systems and provides a unique digital sandbox for real-time fabric simulation that can be used for network design, testing, and troubleshooting. FSP-certified designs reduce fabric design times and simplify Day 0, Day 1, and Day 2 planning activities. These capabilities give NetOps teams greater confidence at all stages of large-scale fabric deployment and operations, enabling them to operate more efficiently, at a lower cost, and with fewer personnel.
Nokia’s data center switching portfolio offers massive scale and resilience, providing a solid foundation for data center and cloud networks. The portfolio includes the Nokia 7250 Interconnect Router (IXR), the Nokia 7220 IXR-H series, and the Nokia 7220 IXR-D series platforms, offering a wide range of high-performance, chassis-based, fixed-form-factor options for top-of-the-line data center applications such as rack (TOR), leaf, backbone, and super-backbone. The platforms support 400GE, 100GE, 50GE, 40GE, 25GE, 10GE, and 1GE interfaces and offer a comprehensive and robust set of capabilities encompassing IP routing, Layer 2 switching, QoS, scalable telemetry, security, and model-based management.
