面向多层递归域名系统的自适应缓存管理方法
An adaptive cache management method for multi-layer recursive DNS
摘要
Abstract
The domain name system(DNS)is a core infrastructure of the internet,and its service quality and efficiency directly impact the operation of the internet.To optimize DNS performance and improve domain name resolution efficiency,this paper proposes an adaptive cache management method for multi-layer recursive DNS.This method dynamically adjusts the cache content of domain name serv-ers based on changes in DNS traffic,thereby enhancing the cache hit rate of the DNS and reducing do-main name resolution time.Experiments demonstrate that the designed multi-layer recursive DNS with adaptive cache management achieves a higher cache hit rate and shorter DNS response latency compared to traditional multi-layer recursive DNS,delivering significant acceleration effects.关键词
