Edge Domain Name Resolution via Centralized Authoritative DNS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The scale of the DNS is too large, maintenance is difficult, and deployment cost is high in edge cloud computing scenarios due to the need for a separate DNS system in each widely distributed edge computer room.
Innovation Solution
A domain name resolution method that converts domain name requests between virtual devices and an authoritative DNS system deployed on separate physical machines in different edge computer rooms, avoiding the need for a separate DNS system in each edge computer room.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate DNS system is deployed in each edge computer room, then domain name resolution can be performed locally, but the scale of the DNS becomes too large and maintenance becomes difficult
Solution Approach 1:
The patent extracts the authoritative DNS system from each edge computer room and consolidates it into a centralized DNS system. The resolver at each edge node handles local resolution requests and forwards them to the centralized authoritative DNS, eliminating the need for separate authoritative DNS systems in each edge location while maintaining local resolution capability through the resolver component.
Solution Approach 2:
The patent merges multiple distributed authoritative DNS systems into a single centralized authoritative DNS system. By combining the DNS functionality that was previously distributed across multiple edge computer rooms into one centralized location, the overall system scale is reduced and maintenance is simplified while the resolver network maintains the ability to serve all edge locations.
2Ease of operation
If a separate DNS system is deployed in each edge computer room, then local domain name resolution is enabled, but deployment cost becomes high
Solution Approach 1:
The patent makes the centralized authoritative DNS system universal by designing it to handle resolution requests from multiple edge computer rooms through a single deployment. The authoritative DNS system serves multiple locations simultaneously, eliminating the need for separate deployments in each edge room while maintaining local resolution capability through the resolver component at each location.
Solution Approach 2:
The patent introduces the resolver as an intermediary component at each edge computer room that localizes the DNS functionality. The resolver acts as a mediator between local virtual devices and the centralized authoritative DNS, enabling local domain name resolution operations without requiring a full authoritative DNS system at each location, thus reducing deployment costs.
3Device complexity
If the DNS scale is reduced by consolidating authoritative DNS, then maintenance becomes easier and cost decreases, but domain name resolution capability must be maintained
Solution Approach 1:
The patent segments the DNS system into two distinct functional components: the authoritative DNS system for managing domain name data and the resolver system for handling resolution requests. This segmentation allows the authoritative DNS to be consolidated into a single location for easier maintenance, while the distributed resolver components at each edge location maintain the domain name resolution capability by forwarding requests to and receiving responses from the centralized authoritative DNS.

AI summary
The present disclosure relates to the field of edge cloud technology, and discloses a domain name resolution method, a system, an apparatus, a device, and a medium for edge computing. The domain name resolution method includes: acquiring a first domain name resolution request forwarded by a virtual device through a network module; converting the first domain name resolution request into a second domain name resolution request, and sending the second domain name resolution request to an authoritative domain name system; and receiving a resolution result of the second domain name resolution request by the authoritative domain name system, and forwarding the resolution result to the virtual device through the network module.
