Domain Name Traffic Scheduling for Immediate Data Center Failover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional traffic scheduling methods in data centers often require changes to domain name resolution results, leading to delayed traffic redirection and reduced reliability during failures.
Innovation Solution
Implementing a traffic scheduling method that modifies domain names to standardized forms including computer room identifiers in real-time at the terminal device, allowing immediate traffic redirection without altering domain name resolution results.

Engineering Contradiction Analysis
1Reliability
If domain name resolution results are changed to redirect traffic to backup computer rooms, then traffic can be directed to variable computer rooms, but the change is not immediately effective, reducing service reliability
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple IP addresses (including backup computer room IPs) in the domain name resolution result before failure occurs. When a computer room fails, the system can immediately switch to using the pre-configured backup IP address without waiting for resolution result updates, thus eliminating traffic redirection delay and improving service reliability
Solution Approach 2:
The patent implements dynamics by making the IP address selection dynamic based on real-time computer room status. The terminal device can dynamically switch between different IP addresses in the resolution result according to the operational status of computer rooms, enabling immediate traffic redirection when failures occur without requiring changes to the resolution results themselves

AI summary
A traffic scheduling method, apparatus and system, a terminal device and a readable storage medium are provided. The method includes: acquiring scheduling configuration information, where the scheduling configuration information indicates a traffic scheduling strategy for a target domain name; modifying the target domain name into a standardized domain name matching the traffic scheduling strategy, in a preset domain naming manner; the standardized domain name at least includes a computer room identifier used to indicate the target computer room after traffic scheduling; and initiating an access request to the target computer room, based on the standardized domain name.
