一种面向HLS协议的CDN主动预热方法和装置
By integrating a real-time warm-up component into the CDN edge service node, and utilizing the Nginx service process in collaboration with the real-time warm-up component, proactive warm-up of the HLS protocol is achieved. This solves the problem of unpredictable origin pulls in high-concurrency scenarios of traditional CDN systems, and improves the smoothness and resource utilization efficiency of HLS live streaming services.

AI Technical Summary
Traditional CDN systems cannot effectively predict the timing of user requests in high-concurrency, weak network, or sudden traffic scenarios, resulting in unpredictable origin server response times. This leads to congestion of origin server egress bandwidth and links, affecting the quality of HLS live streaming services.
A real-time preheating component is integrated into the CDN edge service node. Through the collaboration between the Nginx service process and the real-time preheating component, the active preheating of the HLS protocol is achieved. It intelligently identifies and pre-caches TS segments that may be requested, manages the cache using LRU or LFU strategies, and performs heat analysis and deduplication in conjunction with the TS segment pool management module.
It effectively reduced playback stuttering caused by unstable origin links, improved the smoothness and user experience of HLS live streaming services, and optimized resource utilization.
