Solution Overview

Problem

Existing DNS configurations face challenges when administrators desire the use of multiple nameservers across devices with varying hardware and software configurations, leading to configuration complexities.

Innovation Solution

A method that involves receiving a DNS configuration from a coordination service, dividing rules into operating system and DNS application rules based on computing element characteristics, and configuring both to implement these rules effectively across different hardware and software configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple nameservers are configured for different domains across diverse devices, then DNS resolution flexibility and adaptability improve, but configuration complexity and difficulty increase

Engineering Contradiction:
ImproveDNS resolution flexibilityVSAvoidconfiguration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments DNS configuration into two distinct rule types: operating system rules and DNS application rules. This segmentation allows different portions of the DNS configuration to be applied at different levels (OS vs. application), thereby reducing the complexity of managing multiple nameservers across diverse devices while maintaining the flexibility to direct different domains to different nameservers.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If DNS configuration rules are applied uniformly across all devices, then ease of deployment improves, but adaptability to different hardware and software configurations deteriorates

Engineering Contradiction:
Improvedeployment easeVSAvoidconfiguration adaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements local quality by creating device-specific DNS configurations tailored to each device's hardware and software characteristics. The system generates customized configuration files that incorporate device identifiers and specific rule sets appropriate for each device type, enabling both easy deployment through automated generation and high adaptability to diverse computing environments.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If DNS configuration is customized for each device type, then adaptability to hardware and software variations improves, but configuration management complexity increases

Engineering Contradiction:
Improveconfiguration adaptabilityVSAvoidconfiguration management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements self-service by enabling each computing device to automatically receive and apply its own customized DNS configuration file from a coordination service. The system autonomously generates device-specific configurations based on device characteristics and automatically applies the appropriate rules, eliminating the need for manual configuration management and reducing overall system complexity despite high adaptability.

Inventive Principle:
Principle #25Self-service

4Device complexity

If a single DNS resolver is used, then system simplicity improves, but DNS resolution efficiency and flexibility deteriorate

Engineering Contradiction:
Improvesystem simplicityVSAvoidDNS resolution efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent segments the DNS resolution function by implementing multiple nameservers that can be selectively used based on the domain being queried. This allows the system to maintain simplicity by using a coordinated rule-based approach while improving efficiency and flexibility by directing different domains to specialized nameservers, achieving both goals simultaneously.

Inventive Principle:
Principle #1Segmentation

AI summary

The technology described herein manages nameserver rules for domain name system (DNS) requests across multiple hardware and/or software configurations. In one implementation, a method includes receiving a domain name system (DNS) configuration from a coordination service at a computing element. The DNS configuration comprises rules associating at least one domain name with a nameserver of a plurality of nameservers. The method further includes dividing the rules into operating system rules and DNS application rules depending on one or more characteristics of the computing element. The method also includes configuring an operating system of the computing element to implement the operating system rules and configuring a DNS application executing on the computing element to implement the DNS application rules. Additionally, the method includes applying the operating system rules in the operating system and the DNS application rules in the DNS application.
