Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Cisco® Cloud Native Broadband Router (cnBR) transforms a cable network’s headend, virtualizing hardware-based Converged Cable Access Platform (CCAP) services, delivering the advantages of web-scale operations in a resilient, elastic, and openly composable set of microservices.

Product overview

Cable networks are undergoing a major transformation, migrating from analog to digital systems, adding capacity and scale, and deploying new and improved service features to support the increasing needs of their customers. Replacing analog systems with digital devices such as Remote PHY and Converged Interconnect Network (CIN) routers and switches is a preparation for what is to come: the transformation of the cable headend. With a digital access network, cable services reliant on headend hardware are no longer tied to physical hardware–based solutions.

The Cisco Cloud Native Broadband Router is a fundamental rewrite of the CCAP, virtualizing the once hardware-based services with a truly cloud-native design, offering unprecedented service velocity, highly simplified operations, and economic scalability for profitably operating your network. Instead of lifting and shifting existing code from legacy hardware and placing it in the cloud to run as a virtual machine, the Cloud Native Broadband Router is a full software rewrite for CCAP-enabled services, built as a composable set of microservices that utilize standard tools such as Kubernetes for container orchestration and Docker for creating, deploying, and running containerized applications. The end result is a highly-scalable and resilient platform designed with automation in mind. Its API-driven architecture, developed for CI/CD DevOps workflow and intuitive and customizable dashboard have the goal of simplifying network operations and increasing feature deployment speed.

The Cisco Cloud Native Broadband Router utilizes Cisco Operations Hub (Ops Hub) as the single plane of glass dashboard to configure, monitor and operate the platform. Operations Hub follows the same cloud native principles with high-resiliency, microservices-based architecture designed to be fully customizable, leveraging best-in-class open source tools.

Features and benefits



Cloud native

Composable, elastic, and resilient network services that optimize resource utilization and increase service velocity from ideation to revenue-generating deployments.


Quickly develop, test, and deploy new services. Update features and functions without downtime. Autoprovision and scale services more efficiently. Highly resilient operation, thanks to small blast radius inherent in microservices.

Containerized software architecture

Each part is packaged in its own software container. Facilitating reproducibility, composability, transparency, and resource isolation. Enables highly efficient resource utilization, with granular and elastic scaling as well as fast recovery after a failure, thanks to a lightweight microservices-based design.

Streaming telemetry

Gain visibility into all aspects of system operation, in a lightweight fashion that minimizes resource effects.

Full lifecycle management

Simplify all aspects of the CCAP lifecycle, from initial deployment to real time monitoring, software upgrades, feature updates, and more.

Single Pane of Glass

OperationsHub allows customers to manage multiple cnBR instances across multiple geographic deployments. data plane

High performance and flexibility for the network data plane using Commercial Off-The-Shelf (COTS) servers. Software written with versatility to rapidly adopt hardware innovations as they become available.

API-centric design

Simplify operations and begin automating with direct programmatic access to CCAP services and functions using open interfaces and tools.

Kubernetes container orchestration

Open-source cluster and container management, orchestrating server hardware resources to be efficiently shared with other cloud-native applications, virtual network functions, and general-purpose web services.

Open standards

Built with open-source software and tools for integrating with all ecosystems. Using open standards for software development makes the Cloud Native Broadband Router adaptable for new technology and the evolving needs of the network.

CI/CD software updates and upgrades

Enables software upgrades to be performed early and often in a seamless fashion without disrupting services. Continuously deploy new services and features early and often while minimizing risk with Canary deployments.

Hardware disaggregation

Compatible with bare metal and designed to be portable across multicloud environments.
