Virtualized Access Platform

Harmonic Software-Based Cable Access Networks

CableOS® Core CMTS software allows cable operators to achieve multi-gigabit broadband capacity while simultaneously lowering their space and power requirements. Running on a 1-RU HPE Intel-based x86 server, the software eliminates the need to purchase space-consuming and expensive hardware-based CMTS platforms, allowing operators to break away from the cycle of needing to upgrade hardware every three years to accommodate capacity growth requirements. Regular CableOS software upgrades accelerate the introduction of new features, including next-generation standards, DOCSIS 3.1 capabilities abd beyond, XGS-PONand capacity is gained simply by adding new 1-RU servers. It;s ready for year 2050.

Overview

CableOS® solution is a revolutionary approach to modern execution of cable access platform. Traditional systems with big iron Cable Modem Termination System are replaced with CableOS core – based on standard Intel x86 server solution, CIN network element – to put it simply – an ethernet switch and either in-place Remote-PHY shelf or  Remote-PHY in a node. Accompanied by industry standard PTP clock, CableOS solution leverages on the standard hardware and easy to develop Remote-PHY and by using software CMTS allows for quick implementation, easy innovation and ability to scale at an unobtianable speed factor when compared with traditional solutions.

Unprecedented scalability with smooth implementation

The CableOS® solution allows any operator to start small, grow big or replace existing system in much showrter time-to-market. Core software runs on an Intel® x86-based server, so you no longer need to purchase space-consuming and expensive hardware-based CMTS platforms, and you can break away from the cycle of needing to upgrade hardware every three years to accommodate your capacity growth requirements. You can start with as little as single server, and add capacity gradually. Thanks to cluster approach it is as easy as wiring the new unit and it will be automatically taken under the wings of cluster manager. It could be for redudancy, or capacity – you decide. The beggining is just a few service groups and before you know it – it will gradualy scale to 100+ service group system. The management interface based on Graphana and metrics database allows for real-time presentation of the health, numbers and performance of the system.
The CableOS® solution is best fit from all perspectives for very small, medium and pan-conutry MSO.

DAA: End-to-end Remote PHY solution

The modular architecture at it’s literal core allows for flawless Remote-PHY implementation. If you are seeking to deploy a fiber deep network that can support both IP and legacy services, Harmonic’s CableOS® solution can help you simplify the migration. In addition to moving RF components out of the headend and into the field, decoupling the CCAP core from the physical layer in a Remote PHY architecture leverages the benefits of digital fiber, such as signal transport over much longer distances, more wavelengths and improved signal quality.

Multi Access platform from Cable to PON, through DOCSIS 4.0 and 5G backhaul

When it comes to face the fast changing requirements of moderns network MSO are looking for stable but future-proof solution. Beggining with delivering 1Gbps and beyond for end-customer CableOS® solution quickly implements Remote-PHY and Shelf but is also implementing XGS-PON OLT solution based on modular architecture. COTS hardware allows for integration and contenerized architecture of the software part allows to add XGS-PON functionality to Core system while maintaning the same IP-delivery and consistent offering for the users . The next step – DOCSIS 4.0 – means that MSO can gradualy migrate the Remote-PHY part of the network to much needed speed and capacity upgrades. Ability to dedicate CPU cores to tasks ahead allows for providing unmatched low-latency needed for providing 5G and beyond backhaul capability. To top that time synchronization which is based on PTP clock is in sync with other new access platforms timing requirements – blending the platform even more.

Cloud native solution with NFV and contenerized architecture

Kubernetes – K8s explained

The Intel® x86-based server as the core hardware of the shelf is one of the key components that allow to achieve all the goals quickly and with little extra effort. It’s not just redundancy, thanks to NFV and OS native functions system allows from day one very high avaliablity, with quick, short-window based upgrades. Ability to dedicate cores to functions ensures stable packet, low-latency and jitter-free performance. Switching over is as easy as one command. Advanced load-balancing techniques are ready to integrate with MSO’s current backend system. 
The single difference that is outstanding when it comes to cloud based systems is the use of containers. Think of them as isolated portions of your requirments which are packaged as working unit which can be replaced, copied across but still retain the quickest connections and is state aware.
Kubernetes containers allow for direct usage of resources and are ready to demand the same performance from bare-metal and virtualized enviroments.
Industry’s quick adoption of this solution and widespread use confirm that they are the best choice. In future they will allow creating an approach where customer has his own CPU core with CMTS, PON OLT, 5G RAN or other access method that he requires.
