Distributed ONU Configuration Conversion in DOCSIS-over-PON
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing DOCSIC-over-PON systems, a performance bottleneck occurs when a large number of ONUs/ONTs require centralized configuration processing, affecting service provisioning efficiency due to the need for an independent server to translate DOCSIS-based protocols to PON-based protocols.
Innovation Solution
The method involves ONUs/ONTs switching to a virtual CM mode, obtaining DOCSIS-based configuration information from the OSS, converting it into PON-based configuration information, and performing local parameter configuration, thereby enabling efficient service provisioning without modifying the existing OSS and reducing the load on the OLT.

Engineering Contradiction Analysis
1Reliability
If an independent server is used to centrally process configuration files of ONUs/ONTs, then protocol translation from DOCSIS to PON can be achieved, but a performance bottleneck occurs when a large number of ONUs/ONTs exist in the network
Solution Approach 1:
The patent divides the centralized configuration processing function into distributed processing units located at each ONU/ONT device. Each terminal independently processes its own configuration files and performs protocol conversion locally, eliminating the single-point bottleneck of the central server architecture.
Solution Approach 2:
Each ONU/ONT is equipped with embedded processing capabilities to autonomously handle configuration file processing and protocol translation. The terminals self-configure without requiring centralized server intervention, thereby improving service provisioning efficiency while maintaining protocol compatibility.
2Ease of operation
If configuration files are processed in a centralized manner by an independent server, then service provisioning can be managed uniformly, but service provisioning time is affected due to the performance bottleneck
Solution Approach 1:
The centralized management function is segmented into distributed configuration processing units at each ONU/ONT. This allows parallel processing of configuration files across multiple terminals simultaneously, reducing overall service provisioning time while maintaining management uniformity through standardized protocols.
Solution Approach 2:
Configuration processing capabilities are pre-installed in each ONU/ONT device. When configuration files are received, terminals immediately begin local processing without waiting for centralized server availability, thereby reducing service provisioning time while maintaining standardized configuration management.

AI summary
A method for configuration conversion includes: switching a working mode to a virtual Cable Modem (CM) mode according to a virtual mode switching notification message sent by an Optical Line Terminal (OLT); obtaining first configuration information from an Operations Support System (OSS), the first configuration information being DOCSIS-based configuration information; converting the first configuration information into second configuration information, the second configuration information being PON-based configuration information; implementing local parameter configuration according to the PON-based second configuration information; and sending a configuration complete message to the OLT after the configuration is complete. With the present disclosure, a performance bottleneck problem that might otherwise exist within the OLT art can be solved, and a service provisioning efficiency can be improved.
