Minimize Service Interruption when Upgrading Firmware

Minimize Service Interruption when Upgrading Firmware

SHARE

Managing firmware upgrades can be a daunting task.

Sometimes, engineers must upgrade thousands of devices from different brands and models across a multitude of networks. On top of that, operators require minimal to no service interruption to their customers, or they risk damaging quality of experience.

It’s no secret that MSOs are always trying to manage data, voice, and video services in a cost-effective way. Without an automated solution, configuration changes and firmware updates can add to ongoing administration costs, affecting the company’s bottom line by diverting resources and reducing cost savings.

Imagine a solution for your firmware management that enables you to perform these upgrades in a simple, flexible, and safe way.

Operators can easily orchestrate updates to any amount of subscribers in a few automated steps using the following three groups:

· Client Classes
· Device Classifiers
· Classified Network Settings

These criteria groups give operators the capability to discriminate between devices of the same type, and use configurable tags to enable global influence over services based on MAC address, model, vendor, DHCP options, and so on. Engineers will be able to quickly and accurately upgrade firmware to existing CPE on their networks, saving time and reducing the chance of firmware upgrade errors.

Consider a scenario where you need to initially upgrade a selected group of devices, e.g. 500 cable modems. After this first upgrade, you then want to upgrade the rest.

This can be handled simply by using:

1. A Client Class to identify the modem model
2. A second Client Class to identify the selected group of modems
3. Using Client Class #2 within a device classifier/classified network setting within the modem model Client Class (#1).

Other scenarios may include applying different firmware files to separate groups of devices of the same model.

Simplicity and flexibility are key to a successful firmware upgrade. With the right solution in hand, you’ll be able to manage and deploy firmware upgrades in an easy and controlled way, resulting in accurate firmware management with minimal service interruption to your customers.
