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 the economic scalability for profitably operating your network. The Cisco Cloud Native Broadband Router has been built from the ground up, taking the decades of experience and expertise in networking technologies and completely rewriting the hardware-based CCAP code to be cloud native. 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.
- Cloud native – Composable, elastic, and resilient network services that optimize resource utilization and increase service velocity from ideation to revenue-generating deployments.
- Microservices – 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 – Manage instances across multiple cloud and geographic deployments.
- FD.io/Ligato.io-based 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.
