Solution Overview

Problem

SEBA, a provisioning sequence for PON, cannot be directly applied to APN for End-to-End optical path provisioning, lacking wavelength allocation and 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

VSEngineering Contradiction Analysis

1Reliability

If SEBA provisioning sequence is applied to PON, then authentication of terminal is achieved, but wavelength allocation and optical path provisioning cannot be performed

Engineering Contradiction:
ImproveauthenticationVSAvoidoptical path provisioning
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent extends the SEBA provisioning sequence to support multiple network types (PON and APN) by adding wavelength allocation and optical path provisioning functions. The enhanced sequence now performs authentication, communication scheme setting, wavelength setting, and path setting, making it universally applicable to both PON and APN networks while maintaining the original authentication capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If SEBA only determines conduction/non-conduction based on authentication result, then authentication security is maintained, but wavelength allocation and optical path provisioning are insufficient

Engineering Contradiction:
Improveauthentication securityVSAvoidwavelength allocation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent performs wavelength allocation and optical path provisioning as preliminary actions immediately after authentication success. The enhanced SEBA sequence sets the communication scheme, allocates wavelengths, and provisions optical paths before actual data transmission begins, ensuring that all necessary resources are prepared in advance while maintaining authentication security.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If authentication is performed for newly connected terminal, then network security is ensured, but additional provisioning steps are required

Engineering Contradiction:
Improvenetwork securityVSAvoidprovisioning steps
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges authentication with wavelength allocation and optical path provisioning into a single integrated SEBA provisioning sequence. Instead of performing authentication as a separate step followed by additional provisioning procedures, the enhanced sequence combines all these functions into one unified process, reducing overall system complexity while maintaining network security.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An aspect of the present invention includes: an authentication step of authenticating an optical terminal; a scheme setting step of setting a communication scheme to be used between the terminal and a connection destination terminal to which the terminal is connected; a wavelength setting step of setting a wavelength to be used between the terminal and the connection destination terminal; and a path setting step of setting an optical path to be used between the terminal and the connection destination terminal.
