Enhancing Network Management with Kubernetes
Integrating edge computing and cloud infrastructure has become increasingly critical, and organizations are constantly seeking efficient ways to manage their edge cloud networks to enhance performance, reduce latency, and ensure seamless connectivity. One powerful solution that has emerged is leveraging Kubernetes to automate edge cloud networks. This approach streamlines operations and provides a robust framework for network management.
The Nokia Edge Network Controller, operating as a native resource within Kubernetes, brings a new level of network intelligence to the edge cloud. By integrating network knowledge directly into Kubernetes, this controller empowers networking teams with immediate access to sophisticated network paradigms. Kubernetes, renowned for its orchestration capabilities, extends its reach beyond computing and storage to include network infrastructure, making it the central orchestrator for the entire edge cloud environment.
This integration allows teams to utilize the extensive tools available within the Kubernetes ecosystem to design, build, and maintain the edge network. The network infrastructure operates harmoniously with the applications it supports rather than functioning in isolation. Network engineers can maintain control through Kubernetes’ native role-based access mechanisms, ensuring secure and efficient network management.
Simplifying Network Design and Configuration
The Edge Network Controller offers a streamlined approach for engineering, architecture, and operations teams to automate IP network design and configuration in space-constrained edge clouds. This is achieved through declarative network service intents, requiring minimal input parameters. These intents are programmable and can be applied without needing to upgrade the Edge Network Controller, offering flexibility and ease of use.
Additionally, the controller includes a predefined set of network intents, which network designers and architects can easily edit. This feature supports a wide range of network equipment, including Nokia Service Router portfolios and third-party model-driven routers and switches, for underlay and overlay network configurations.

Kubernetes-Based Network Automation
The Edge Network Controller significantly enhances Kubernetes by embedding network intelligence, facilitating consistent orchestration of containers and networks. By leveraging the Kubernetes API, it integrates network components into the Kubernetes ecosystem, enabling event-driven automation and dynamic network configuration updates aligned with application-specific lifecycle management.
Kubernetes’ role-based access control mechanisms grant network owners the ability to offer specific network services intents to operations teams. The Edge Network Controller can also observe the networks it manages and export relevant information to centralized monitoring and alerting systems like Prometheus.
Technical Specifications
The Edge Network Controller is a lightweight solution designed to be installed locally on an edge cloud server hosting a Kubernetes cluster. It supports Kubernetes Release 1.24, Google Anthos, and Red Hat OpenShift. The gRPC Network Management Interface (gNMI) facilitates communication with network devices. The controller supports Nokia Service Router Linux (Release 22.6 and up) and the Nokia Service Router Operating System (SR OS) (Release 22.5 and up). Installation is streamlined via Helm, with minimal virtualization requirements per worker node (< 1 vCPU and < 1 GB RAM).
Automating edge cloud networks with Kubernetes presents a transformative approach to network management, integrating network intelligence directly into the ecosystem. This solution simplifies network design and configuration and enhances edge cloud environments’ agility, efficiency, and reliability. By leveraging the robust capabilities of Kubernetes and the Edge Network Controller, organizations can achieve seamless, automated network operations, ensuring they are well-prepared to meet the demands of modern digital applications.
