OLT XDR Encoding for ONT Data Management in Hybrid PON-D-CCAP Networks

Solution Overview

Problem

In the context of a hybrid networking scenario combining passive optical networks (PON) and distributed converged cable access platforms (D-CCAP), there is a lack of uniform standards for collecting and reporting ONT data, leading to inefficiencies and increased power consumption in management servers.

Innovation Solution

A data transmission method where an Optical Line Terminal (OLT) obtains a data template, collects corresponding ONT data, encodes it in XDR format, and sends it to a management server, such as an IPDR server, which then stores and manages the data, thereby reducing the need for separate management servers and lowering power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate management server is configured to manage ONT data, then ONT data can be stored and managed, but network deployment costs increase and power consumption increases

Engineering Contradiction:

ImproveONT data management capabilityVSAvoidpower consumption of management server

Core Design Contradiction:

ReliabilityVSUse of energy by stationary object

Solution Approach 1:

The patent merges the ONT data management function into the existing IPDR server that already manages CM data. The IPDR server is enhanced to handle both CM data and ONT data, eliminating the need for a separate management server. This consolidation reduces power consumption and deployment costs while maintaining reliable ONT data management capabilities.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The IPDR server is transformed into a multi-functional server that can handle both CM data and ONT data. By giving the IPDR server universal data management capabilities across different network access technologies (cable and optical), the system avoids deploying separate specialized servers, thereby reducing overall power consumption and infrastructure costs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The IPDR server is transformed into a multi-functional server that can handle both CM data and ONT data. By giving the IPDR server universal data management capabilities across different network access technologies (cable and optical), the system avoids deploying separate specialized servers, thereby reducing overall power consumption and infrastructure costs.
