Solution Overview

Problem

Traditional fiber optical connection modeling in optical networks requires manual updates, leading to increased errors as the number of connections grows, and existing systems lack a connection-agnostic provisioning process for field replaceable units (FRUs) in optical networks.

Innovation Solution

A node comprising a fiber shuffle panel, field replaceable units, and a node controller with a processor and memory that enables auto-provisioning through a 'one-touch' ROADM system, allowing for connection agnostic provisioning by generating and validating associations between optical port pairs and activating services without manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual updates are used for fiber optical connection modeling, then the system is simple to implement, but the error rate increases as the number of connections grows

Engineering Contradiction:
Improveconfiguration accuracyVSAvoidmanual update complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs self-provisioning by automatically generating FRU map data and validating associations between optical port pairs without requiring manual intervention. The node controller autonomously manages connection modeling updates, eliminating human error while maintaining system simplicity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-generates FRU map data and validates all associations before actual service activation. This preliminary configuration ensures that connection models are error-free before being put into operation, improving reliability without adding operational complexity.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the number of fiber optical connections increases to meet bandwidth needs, then the network capacity improves, but the likelihood of configuration errors increases

Engineering Contradiction:
Improvenetwork bandwidth capacityVSAvoidconfiguration error rate
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system validates associations between optical port pairs and generates FRU map data that reflects the actual physical connections. This feedback mechanism ensures that the software model accurately represents the physical network, preventing configuration errors even as the number of connections increases.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system creates an accurate software copy of the physical connection topology through FRU map data generation. This digital twin approach allows the system to manage complex connection configurations without introducing errors, as the software model precisely mirrors the physical infrastructure.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If ports are hardcoded into specific software implementation, then the software structure is simple, but the system lacks adaptability for connection-agnostic provisioning

Engineering Contradiction:
Improveprovisioning flexibilityVSAvoidsoftware architecture complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements a universal FRU map data structure that can represent any field replaceable unit configuration regardless of specific hardware details. This allows the same software architecture to handle diverse connection scenarios without hardcoding, achieving adaptability through standardized data models.

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

Solution Approach 2:

The system separates the physical connection modeling from the software implementation by using FRU map data as an intermediate layer. This segmentation allows the software to remain flexible and adaptable while the physical connections are represented in a standardized, hardware-agnostic format.

Inventive Principle:
Principle #1Segmentation

AI summary

A node comprises an FSP, a first FRU, a second FRU, and a controller. The FSP has a first connector having first port pairs and a second connector having second port pairs, a second port pair is optically coupled to at least one first port pair. The first FRU has third port pairs and a third connector coupled to the first connector. The second FRU has fourth port pairs and a fourth connector coupled to the second connector. The controller comprises a processor and a memory storing an FSP map and instructions, including: receive a first association between a third port pair and one of the first connector and the second connector; validate the first association; generate an FRU map based on the first association and the FSP map; update a mode type for each second association; receive a service activation request; and cause an FRU to activate the service.
