Mesh Network DNS Resource Sharing via Local Exit Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mesh networks, user devices face challenges in accessing domain name service (DNS) resources efficiently, leading to potential privacy compromises and delays when querying domain information for external devices, as they often rely on public DNS servers, which can expose private information and introduce latency.
Innovation Solution
The method involves user devices sharing DNS resources within the mesh network by utilizing local DNS servers connected to a local area network (LAN), where one user device forwards DNS queries to a local DNS server and returns the domain information to other devices, thereby avoiding public DNS servers and maintaining privacy and reducing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user devices rely on public DNS servers for domain queries in mesh networks, then domain information can be obtained, but private information may be exposed and latency increases
Solution Approach 1:
The patent introduces local DNS servers as intermediary components within the mesh network. Instead of directly querying public DNS servers, user devices route DNS queries through nearby mesh network devices that have local DNS servers. This intermediary approach protects user privacy by preventing direct exposure to public DNS servers while maintaining efficient domain resolution through localized queries, thereby resolving the contradiction between privacy protection and latency reduction
2Reliability
If user devices use local DNS servers through mesh network sharing, then privacy is protected and latency is reduced, but network complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where mesh network devices automatically discover and share their local DNS server capabilities with other network participants. Devices autonomously register their DNS server information in the mesh network and dynamically route queries without requiring manual configuration from users. This self-organizing behavior reduces network configuration complexity while maintaining the privacy and performance benefits of local DNS server utilization
3Productivity
If DNS resources are shared across the mesh network, then resource utilization is optimized, but network traffic overhead increases
Solution Approach 1:
The patent applies local quality by enabling DNS query routing to preferentially select the nearest or most appropriate local DNS server within the mesh network based on geographic proximity or network distance. This localized approach ensures that DNS queries are resolved by the closest available DNS resource, optimizing resource utilization efficiency while minimizing network traffic overhead by avoiding unnecessary long-distance transmissions across the entire mesh network
Data Source
AI summary
The disclosure describes a mesh network including a first device and a second device, which acts as an exit device with respect to the first device such that communication between the first device and an external device, outside the mesh network, is communicated via the second device. The first device receives access information utilized by the second device to access a DNS server in a LAN that includes the second device, and transmits a meshnet query packet that includes a DNS query for domain information associated with the external device. The first device receives, based on transmitting the meshnet query packet, the domain information associated with the external device, and transmits a meshnet initiation packet that includes a network communication for communicating with the external device, the network communication including the domain information. Various other aspects are contemplated.
