Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack an effective solution for integrating home network PONs with access network PONs, which is necessary to provide high-quality access services by combining the two networks.
Innovation Solution
The proposed solution involves an authentication system and method for a home network ONU, which includes an integrated device comprising an access network ONU and a home network OLT. This system allows the home network ONU to access the access network OLT through the integrated device, enabling authentication and bandwidth allocation to establish a high-quality access service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If home network PON and access network PON are integrated through an integrated device, then service quality and network functionality are improved, but device complexity increases
Solution Approach 1:
The patent combines access network ONU and home network OLT functions into a single integrated device. This merging allows the device to simultaneously handle access network authentication (via SN registration with access OLT) and home network bandwidth allocation, resolving the contradiction by consolidating multiple network functions into one device rather than requiring separate units for each function.
Solution Approach 2:
The integrated device is designed with multi-functional capabilities: it can authenticate with the access network OLT using SN, register user information, allocate bandwidth for home network ONUs, and manage both access and home network traffic. This universal design enables one device to perform multiple network roles, improving adaptability while managing complexity through unified architecture.
2Reliability
If authentication and bandwidth allocation are performed through the integrated device, then access service quality is improved, but network configuration complexity increases
Solution Approach 1:
The authentication and bandwidth allocation processes are segmented into distinct functional modules within the integrated device. Authentication module handles SN verification with access OLT, while bandwidth allocation module manages home network resource distribution. This segmentation allows each module to be optimized independently, improving reliability through specialized processing while managing overall system complexity through modular architecture.
Solution Approach 2:
The integrated device acts as an intermediary between home network ONUs and the access network OLT. It receives authentication requests from home ONUs, forwards them to the access OLT for SN verification, receives bandwidth allocation responses, and distributes resources to home network devices. This intermediary role simplifies the interaction model and improves service reliability by centralizing the coordination function.
