CWMP / TR-069 ACS Prototype Work

Context / Problem

Continuing my work at Blue Networks GmbH, I focused on Customer Premises Equipment (CPE) management. The task was to evaluate how end devices (e.g., routers) could be remotely managed via the WAN Management Protocol (CWMP / TR-069).

Responsibilities

• Research and evaluation of ACS (Auto Configuration Server) solutions.
• Setup of a prototype for managing CPEs.
• Testing communication between ACS and various end devices.
• Analysis of possibilities for automatic firmware updates and configuration.

Tech Stack

• Protocols: TR-069 / CWMP
• Software: Likely GenieACS (or comparable open-source solution)
• Infrastructure: Linux Server, diverse CPE hardware

Outcome

• Successful setup of a Proof-of-Concept (PoC) system.
• Insights into the interoperability of different CPE manufacturers with the ACS.
• Assessment of TR-069’s suitability for the company’s specific requirements.

Lessons Learned / Next Steps

TR-069 is a powerful but complex protocol. Interoperability between different vendors is often a challenge. In the future, modern approaches like USP (TR-369) are gaining importance.
