Repeater Network Merging via Weight-Based Configuration Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing repeater networks face challenges in merging multiple independent networks with separate wireless configurations into a single network and in connecting networks with different group IDs, requiring mechanisms to determine the direction of configuration flow and transfer.
Innovation Solution
A method where repeaters establish communication links to connect with each other, determine if group IDs are identical, and compare weights to decide the direction of configuration flow, allowing networks with different group IDs to merge and share configurations by establishing communication links between host and client interfaces, and using action frames to manage configuration updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent repeater networks operate separately with different SSIDs, PMKs and channels, then each network maintains its own stable configuration, but the networks cannot share configurations and form a unified network
Solution Approach 1:
The patent introduces a root repeater as an intermediary that mediates configuration management between multiple independent repeater networks. The root repeater receives configuration information from child repeaters and distributes it to other networks, enabling configuration sharing without direct complex interactions between all networks. This resolves the contradiction by providing a centralized coordination point that simplifies the merging process.
Solution Approach 2:
The patent implements preliminary actions by having repeaters pre-establish communication links and exchange configuration information before actual network merging occurs. The root repeater is designated in advance, and configuration data is prepared and transmitted beforehand, allowing networks to merge smoothly without ad-hoc complexity during the merging process.
2Loss of information
If repeaters establish communication links to share configurations, then configuration sharing is enabled, but determining the direction of configuration flow becomes complex
Solution Approach 1:
The patent applies asymmetry by designating a root repeater with a specific role that is different from child repeaters. The root repeater has the authority to receive and distribute configuration information, while child repeaters only send configuration to the root. This asymmetric relationship simplifies the configuration flow determination, as all configuration flows converge to and diverge from the root, eliminating the need for complex peer-to-peer direction determination.
Solution Approach 2:
The patent implements local quality by assigning different functional roles to different repeaters based on their position in the network hierarchy. The root repeater has the quality of being a configuration aggregator and distributor, while child repeaters have the quality of being configuration sources. This localized functional differentiation simplifies the overall configuration flow management.
3Adaptability or versatility
If networks with different group IDs are allowed to connect, then network merging flexibility is improved, but network security and identification become more complex
Solution Approach 1:
The root repeater acts as an intermediary that handles group ID management when networks with different group IDs merge. Instead of requiring all repeaters to directly manage and compare group IDs, the root repeater receives configuration information containing group ID data and distributes it appropriately, simplifying the interconnection process while maintaining security.
4Adaptability or versatility
If dual-band repeaters connect to multiple repeaters through two client interfaces, then network connectivity is improved, but configuration conflict and decision-making complexity increase
Solution Approach 1:
The patent applies asymmetry by designating specific interfaces as host interfaces and client interfaces with different functional roles. The client interfaces are used for connecting to parent repeaters, while host interfaces serve child repeaters. This asymmetric interface assignment simplifies configuration decision-making, as each interface has a predetermined role and configuration flow direction, eliminating conflicts even in dual-band repeaters with multiple interfaces.
Data Source
AI summary
Each independent repeater network may be associated with a respective network weight and a respective group identifier. When two repeater networks with the same group identifier merge, configuration may flow from the network with a higher network weight to the network with a lower network weight. When two repeater networks with different group identifiers merge, configuration may flow from the connecting host interface of a repeater of one of the networks to the connecting client interface of a repeater of the other network. In cases of simultaneous connection between two networks, group identifier change may take precedence over configuration update caused by the merging of the two networks.
