Gateway Master Selection via Service Version Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As home networks expand, managing multiple gateways to provide seamless service becomes challenging, especially when a new gateway is added, leading to disruptions in network service.
Innovation Solution
A method and device that retrieve and compare service lists and version information among gateway devices to determine and update the master gateway, ensuring seamless operation and the latest service version across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new gateway is added to the home network, then the network coverage and service capability are improved, but the network service is disrupted and seamless operation is lost
Solution Approach 1:
The patent applies preliminary action by having the new gateway retrieve and compare service lists and version information from existing gateways before becoming active. The gateway determines whether to become master gateway based on version comparison, preventing service disruption by preparing the transition in advance rather than forcing an immediate takeover that would interrupt ongoing services.
2Adaptability or versatility
If a new gateway is added to the home network, then the service version is updated, but the network stability is compromised
Solution Approach 1:
The patent implements feedback by having the new gateway retrieve service lists and version information from existing gateways, compare the versions, and make an informed decision about whether to become the master gateway. This feedback loop ensures that version updates only occur when appropriate, maintaining network stability while enabling service version improvements.
3Manufacturing precision
If version comparison is performed among gateways, then the latest service version is ensured, but the device complexity increases
Solution Approach 1:
The patent applies self-service by enabling each gateway to autonomously retrieve service lists, compare version information, and determine its own role as master or slave gateway. This self-service mechanism eliminates the need for complex centralized coordination, reducing overall system complexity while ensuring proper version control through decentralized autonomous decision-making.
Data Source
AI summary
A gateway device performs a method for determining a master gateway device. In the method, the gateway device retrieves one or more other gateway devices and sends a request for a service list to the retrieved other gateway devices. Also, the gateway device receives the service list and version information of each service, and based on the received version information of each service, determines whether to change the master gateway device.
