Mesh Network Repeater Prevents Packet Looping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Packet looping occurs in mesh networks, causing packets to circulate in loop paths and preventing transmission to external networks, leading to service disruptions and delays.
Innovation Solution
A repeater with an uplink and downlink wireless transmission interface, controlled by a processing unit, turns off the downlink wireless transmission function when the uplink is disconnected from the network, using service set identifiers (SSIDs) to manage connections and prevent packet looping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If nodes are arbitrarily connected in mesh network, then network flexibility and ease of operation are improved, but packet looping occurs causing transmission delays and service disruptions
Solution Approach 1:
The repeater implements a feedback mechanism by monitoring the connection status of its uplink interface and dynamically adjusting the downlink interface state accordingly. When the uplink disconnects from the network, the repeater detects this change and feeds back to the downlink interface to turn it off, preventing packet looping. This closed-loop control resolves the contradiction by maintaining network flexibility while eliminating transmission delays caused by arbitrary connections.
Solution Approach 2:
The patent applies dynamics by making the downlink wireless transmission interface state changeable based on uplink connection status. Instead of a fixed connection state, the system dynamically adjusts the downlink interface between on and off states according to real-time network conditions. This dynamic behavior prevents packet looping while preserving network flexibility when properly connected.
2Reliability
If downlink wireless transmission function remains on when uplink is disconnected, then network service availability is improved, but packet looping occurs preventing transmission to external networks
Solution Approach 1:
The system applies preliminary anti-action by proactively turning off the downlink wireless transmission function when the uplink disconnects from the network. This preventive measure stops packet looping before it can occur, eliminating the harmful effect while maintaining service reliability through proper connection management. The repeater anticipates potential packet looping and takes preemptive action to prevent it.
3Adaptability or versatility
If multiple repeaters are connected in mesh network, then network coverage and adaptability are improved, but complexity of detecting and measuring connection status increases
Solution Approach 1:
The patent applies segmentation by dividing the mesh network into independent repeater units, each with autonomous connection status detection and control capabilities. Each repeater independently monitors its own uplink connection status and controls its downlink interface without requiring complex centralized monitoring. This segmentation simplifies connection status detection while maintaining network coverage through distributed intelligence.
