Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Ethernet service configuration devices in passive optical networks (PONs) suffer from high coupling between Ethernet service configuration and other service/device configurations, which hinders ONT maintenance and modularization, and lack loop-back fault detection capabilities.
Innovation Solution
The introduction of an Ethernet service configuration device and method that includes a PON protocol processing module, an Ethernet module with a MAC bridge port configuration data ME, and a service module with an Ethernet service termination point ME, allowing for decoupling of Ethernet service configuration from other configurations and enabling loop-back fault detection by setting the Ethernet service termination point ME between the MAC bridge port configuration data ME and the non-Ethernet service functional termination point ME.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If Ethernet service configuration is highly coupled with other service/device configurations in existing PON systems, then configuration management is simplified, but ONT maintenance difficulty increases and modularization is hindered
Solution Approach 1:
The patent segments the configuration management system by introducing a dedicated Ethernet service configuration device that operates independently from other service configurations. This device includes specific modules for Ethernet service configuration, fault detection, and management, allowing it to be maintained and updated separately without affecting other PON system components.
Solution Approach 2:
The Ethernet service configuration device acts as an intermediary between the OLT and the ONT, specifically handling Ethernet service configuration tasks. This mediator approach isolates Ethernet service management from other configuration functions, improving maintainability while preserving overall system integration.
2Stability of the object's composition
If Ethernet service configuration is highly coupled with other service/device configurations in existing PON systems, then system integration is maintained, but modularization is hindered
Solution Approach 1:
The configuration management system is segmented into independent functional modules, with the Ethernet service configuration device as a distinct modular unit. This segmentation enables the system to maintain stable integration while allowing individual modules to be adapted, updated, or replaced independently.
Solution Approach 2:
The Ethernet service configuration device is designed as a universal module that can be applied across different PON system configurations and service types. Its standardized interface and functions allow it to work with various service modules while maintaining system integration stability.
3Device complexity
If existing PON systems lack loop-back fault detection capabilities, then system simplicity is maintained, but fault detection capability is insufficient
Solution Approach 1:
The Ethernet service configuration device includes preliminary fault detection mechanisms that proactively identify potential issues before they affect service quality. Loop-back detection functions are built into the configuration device, allowing continuous monitoring of Ethernet service integrity without adding complex external detection systems.
Solution Approach 2:
The configuration device implements feedback mechanisms through loop-back detection, where configuration parameters and fault status are continuously monitored and reported back to the management system. This feedback loop enables real-time fault detection while maintaining relatively simple system architecture.

AI summary
An Ethernet service configuration device, method, and system in a passive optical network (PON) are provided. The device includes a PON protocol processing module, an Ethernet module, and at least one service module based on Ethernet which are sequentially connected. The Ethernet module includes a media access control (MAC) bridge port configuration data management entity (ME) and an Ethernet service termination point ME connected with each other. The service module based on Ethernet includes at least one non-Ethernet service functional termination point ME correlated with the Ethernet service termination point ME. According to the device, method, and system, the coupling between Ethernet service configuration and all kinds of service and/or device configurations based on Ethernet is reduced, which is propitious to the ONT maintenance and modularization configuration.
