Designing a Cloud-Based DOCSIS Time Protocol Calibration Database (2021)

By Roy Sun, Rahil Gandotra, Ph.D. & Mark Poletti, CableLabs, Inc.; Jennifer Andreoli-Fang, Ph.D., Amazon Web Services (AWS); Elias Chavarria Reyes, Ph.D., Hitron Technologies, Inc.; John Chapman, Cisco Systems, Inc.

This paper will detail the design and implementation of a cloud-based application to enable DOCSIS Time Protocol (DTP) deployment. This application is unique to the cable environment and its implementation can serve as a reference design for future cable cloud applications.

The key components of the app will be a database and an application programming interface (API). The application can be implemented on multiple cloud platforms. We chose to prototype our application on Amazon Web Services (AWS). The architecture design will follow the AWS Well-Architected Framework to leverage the benefit of the cloud and will provide horizontal scalability, pay-as-you-go cost structure, and high availability. The application will also be designed for service assurance, which is critical in field deployments. All cloud-based components and a CMTS emulator with the API client will be implemented on AWS.
