Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual traffic construction is used to detect service quality, then detection can be performed, but it is time-consuming and laborious with low precision
Solution Approach 1:
The patent applies the copying principle by having the edge node copy incoming request packets to generate test traffic for the secondary CDN system. Instead of manually constructing test traffic, the system automatically replicates real user requests, which significantly reduces detection time and labor while maintaining high precision through automated comparison of original and copied request responses.
2Measurement precision
If manual traffic construction is used to detect service quality, then detection can be performed, but it requires significant labor input
Solution Approach 1:
The system implements self-service automation where the edge node automatically copies request packets and the detecting node automatically compares responses without human intervention. The automated workflow includes: receiving copy instructions, automatically copying requests, sending to secondary CDN, and comparing responses - all performed by the system itself, eliminating manual labor while maintaining high detection precision.
3Speed
If converged CDN switching is implemented, then response speed improves and costs reduce, but service quality of the target CDN system may not meet requirements
Solution Approach 1:
The patent applies preliminary action by performing service quality detection before CDN switching occurs. The detecting node sends copy instructions to the edge node to test the secondary CDN system in advance, comparing its response quality against the primary CDN. This preliminary testing ensures that only CDNs meeting quality requirements are switched to, maintaining reliability while benefiting from improved response speed and reduced costs.

AI summary
The present application discloses a method and a system for detecting service quality of a CDN system. The method comprises: sending, by a detecting node, a copy instruction to an edge node; copying, by the edge node, received first request information to generate second request information after receiving the copy instruction; sending, by the edge node, the second request information to a CDN system to be detected; acquiring, by the detecting node, first response information corresponding to the first request information, and acquiring second response information corresponding to the second request information from the CDN system to be detected; and comparing, by the detecting node, the first response information with the second response information, to acquire service quality of the CDN system to be detected.
