Optical Terminal Provisioning With Wavelength and Path Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
SEBA, a provisioning sequence for PON, cannot be directly applied to APN as it does not support wavelength allocation or optical path provisioning to newly connected terminals.
Innovation Solution
An optical communication method and apparatus that includes authentication, communication scheme setting, wavelength setting, and optical path setting to authenticate and provision newly connected terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SEBA provisioning sequence is applied to APN, then authentication of terminal can be performed, but wavelength allocation and optical path provisioning cannot be performed
Solution Approach 1:
The patent extends the SEBA provisioning sequence to make it universally applicable to APN by adding wavelength allocation and optical path provisioning steps. The enhanced provisioning sequence now performs multiple functions: authentication, wavelength allocation, and optical path setup, allowing a single standardized procedure to work across different network types including APN.
Solution Approach 2:
The provisioning process is divided into distinct sequential steps: authentication step, wavelength allocation step, and optical path provisioning step. This segmentation allows each function to be performed independently in a structured manner, resolving the limitation where SEBA could only authenticate but not allocate wavelengths or provision optical paths.
2Reliability
If SEBA only determines conduction/non-conduction of main signal based on authentication result, then authentication security is maintained, but wavelength allocation and optical path provisioning to newly connected terminal cannot be performed
Solution Approach 1:
The patent performs wavelength allocation and optical path provisioning as preliminary actions immediately following authentication, before the terminal begins actual communication. This ensures that security requirements are met through authentication while simultaneously preparing all necessary communication resources (wavelengths and optical paths) in advance, making the overall provisioning process smoother and more efficient.
