Optical Line Terminal Service Mapping for Shared PON
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing passive optical network systems, each service provider manages and maintains their own dedicated network, leading to resource waste and complex management, as well as increased construction and maintenance costs due to repeated infrastructure setup and service provider changes.
Innovation Solution
Establishing a corresponding relationship between an optical network unit's device identifier and the service provider, allowing the system to determine and process services based on this identifier, enabling efficient management and maintenance within a shared network infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each service provider establishes a dedicated optical network, then service provider independence and dedicated network management are improved, but construction costs and resource waste increase significantly
Solution Approach 1:
Multiple service providers share a common optical network infrastructure (ODN, OLT) instead of each provider having dedicated networks. The patent merges network resources by allowing different service providers to coexist on the same physical infrastructure, eliminating repeated construction of optical fibers and ancillary facilities.
Solution Approach 2:
The optical network infrastructure is designed to serve multiple service providers simultaneously through universal access mechanisms. The OLT device can identify and route services to different service providers using device identifiers, making the infrastructure multi-functional and adaptable to various providers without requiring separate dedicated networks.
2Adaptability or versatility
If each service provider performs separate service management and maintenance, then service provider autonomy is improved, but management complexity and maintenance costs increase
Solution Approach 1:
The OLT device acts as an intermediary between service providers and the optical network infrastructure. It maintains a correspondence relationship between device identifiers and service providers, enabling centralized management while allowing service providers to independently manage their services through the unified platform.
Solution Approach 2:
A unified service management system is implemented that can handle multiple service providers through a single interface. The system provides universal service management capabilities that work across different providers without requiring separate management systems, thereby reducing complexity while maintaining provider autonomy.
3Reliability
If dedicated optical networks are laid for each service provider, then network isolation and security are improved, but construction costs and infrastructure investment increase
Solution Approach 1:
The patent combines multiple service provider networks into a shared infrastructure, eliminating the need for separate optical fiber layouts for each provider. This merging approach maintains network functionality while significantly reducing the quantity of infrastructure materials required.
Solution Approach 2:
Instead of creating physical copies of dedicated networks for each service provider, the system uses logical separation through device identifiers and software-based service routing. This virtual copying approach maintains network isolation and security without requiring duplicate physical infrastructure.
4Adaptability or versatility
If service providers use separate networks, then service independence is improved, but service switching complexity and user inconvenience increase
Solution Approach 1:
The OLT device serves as an intermediary that enables seamless service switching between different service providers. By maintaining a correspondence relationship between device identifiers and service providers, the system allows users to switch services without physical reconfiguration, making the switching process simple and convenient.
