Solution Overview

Problem

In large-scale FTTR networks, the number of slave devices exceeds the management capacity of a single master device, leading to independent operation of sub-networks without unified management and control.

Innovation Solution

The FTTR network is divided into a control layer and an access layer, with a control device generating control instructions for slave devices via master devices, using a control device to elect and manage slave devices across sub-networks through a unified management system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single master device manages slave devices, then the management structure is simple, but the network cannot support large-scale deployments exceeding the master device's management capacity

Engineering Contradiction:
Improvemanagement structureVSAvoidnumber of slave devices
Core Design Contradiction:
Device complexityVSQuantity of substance

Solution Approach 1:

The network is segmented into multiple areas, each with its own master device managing a limited number of slave devices. This divides the large-scale network into manageable sub-networks, allowing each master device to operate within its capacity while collectively supporting a large number of slave devices across the entire network.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If the network is divided into multiple independent areas with separate master devices, then the network can support large-scale deployments, but unified management and control cannot be realized

Engineering Contradiction:
Improvenumber of slave devicesVSAvoidunified management capability
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The master device acts as an intermediary between the control device and slave devices. The control device sends control instructions to the master device, which then translates and forwards them to the appropriate slave devices. This intermediary role enables unified management from the control device while maintaining the distributed area structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Quantity of substance

If additional master devices are deployed to manage more slave devices, then the management capacity increases, but network costs increase

Engineering Contradiction:
Improvenumber of slave devicesVSAvoidnetwork cost
Core Design Contradiction:
Quantity of substanceVSLoss of energy

Solution Approach 1:

The master device performs multiple functions: it manages slave devices within its area, translates control instructions from the control device, and participates in the overall distributed management architecture. This multi-functionality allows the network to scale without proportionally increasing the number of master devices, as each master device serves multiple purposes.

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

AI summary

A method, apparatus, network device and a storage medium for managing a device, which relate to the technical field of communications. The method comprises the following blocks: a first master device among a plurality of devices included in a control layer of an FTTR network obtains a first control instruction from a control device in the control layer, the first control instruction corresponding to a first slave device in an access layer managed by the first master device; translating the first control instruction into a second control instruction; sending the second control instruction to the first slave device. This solution can realize unified management and control of all devices in an FTTR network.
