Decentralized Network Node Failure Recovery via Beacon and Port Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In decentralized networked lighting systems without a central controller, detecting and recovering from failed nodes is challenging due to the lack of a central device for monitoring and automatic reconfiguration of replacement nodes.
Innovation Solution
A linked list topology is established among network nodes, where each node knows its neighbor's IP address, sends periodic beacons, and checks the port status with a switch device to identify and automatically reconfigure a replaced node, ensuring adaptive failure recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a decentralized architecture is used without a central controller, then system robustness and ease of operation are improved, but the ability to detect and recover from node failures deteriorates
Solution Approach 1:
Each network node autonomously performs failure detection by sending beacon signals and checking port status with switch devices, and automatically reconfigures replacement nodes without requiring a central controller. The system serves itself through distributed intelligence at each node level.
Solution Approach 2:
Nodes implement continuous monitoring through beacon signal exchanges and port status checks, creating a feedback mechanism that detects failures and triggers automatic reconfiguration. The heartbeat mechanism provides ongoing system state information to maintain robustness.
2Manufacturing precision
If manual reconfiguration is performed after node replacement, then configuration accuracy is improved, but recovery time and productivity are worsened
Solution Approach 1:
The system performs preliminary actions by pre-configuring replacement nodes with necessary identification information before they are fully integrated into the network. Switch devices pre-establish port status data that will be used for automatic reconfiguration, eliminating the need for manual configuration steps.
Solution Approach 2:
Replacement nodes automatically receive their configuration data from neighboring nodes and switch devices without human intervention. The system self-configures by transferring identification information and establishing new connections based on detected failure conditions.
3Reliability
If a linked list topology with periodic beacons is implemented, then node detection capability is improved, but energy consumption and device complexity are worsened
Solution Approach 1:
Nodes send beacon signals at periodic intervals rather than continuously, allowing the system to detect node presence and failures while reducing energy consumption compared to continuous transmission. The periodic nature balances detection reliability with power savings.
Solution Approach 2:
The beacon mechanism serves multiple functions: it announces node presence, carries identification information for reconfiguration, and enables heartbeat monitoring for failure detection. This multi-functionality reduces the need for separate dedicated systems.

AI summary
The present invention relates to a method and an apparatus for failure recovery in a network system, wherein a linked list is created, where each network node knows the network address of its neighbor node in at least one direction, wherein each network node sends a beacon to its neighbor node and has its neighbor node acknowledge receipt of the beacon, and wherein a network node checks with a switch device the port status of a port to which a neighbor node that has failed is connected in order to identify a replacement node.
