Centralized PON Controller for OLT Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current passive optical network (PON) management techniques require separate PON controller devices for each network, leading to inefficient resource utilization and poor network performance due to delayed data transmission and remedial actions.
Innovation Solution
A network device with integrated PON controller capabilities that configures and manages both local and remote optical line terminals (OLTs) and optical network units (ONUs), using bridges to connect with other network devices, thereby conserving resources and improving data transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate PON controller devices are used for each network, then each network can be managed independently, but resource utilization becomes inefficient and data transmission is delayed
Solution Approach 1:
The patent combines multiple PON controller devices into a single centralized PON controller that can manage multiple optical line terminals across different networks. This consolidation eliminates the need for separate controller devices for each network, improving resource utilization and reducing data transmission delays while maintaining the ability to manage each network independently through logical separation of OLT management functions.
2Reliability
If separate PON controller devices are used for each network, then each network has dedicated control capabilities, but resource consumption increases
Solution Approach 1:
The patent implements a universal PON controller that can perform multiple control functions across different networks and optical line terminals. This single controller device is designed to handle diverse management tasks including configuration, monitoring, and control of multiple OLTs, thereby reducing the total number of controller devices needed and lowering overall resource consumption while maintaining dedicated control capabilities for each network through software-based management.
3Productivity
If centralized management is implemented across multiple devices, then resource utilization improves, but device complexity increases
Solution Approach 1:
The patent segments the centralized PON controller into multiple functional modules, each responsible for specific management tasks such as OLT configuration, ONU management, and performance monitoring. This modular architecture allows the controller to manage multiple optical line terminals efficiently while keeping the system complexity manageable through clear separation of concerns and independent module operation.
