摘要: 随着互联网的快速发展,增加根镜像服务器的引入数量已成为趋势,为此提出了一套科学合理的理论,从多角度为我国规划引入部署根镜像服务器提供参考。首先结合现阶段我国根镜像部署的实际情况,给出了总体引入部署策略;然后通过数据分析给出了根镜像引入数量和类型建议;接着利用探测或采集等手段获取了我国根解析数据、递归解析服务数据以及互联网发展状况等多方数据,通过归一化加权计算模型,计算得到推荐部署根镜像的省份和运营商网络;最后从制度和技术两方面,给出了根镜像服务监管建议。研究结果表明,可以通过科学手段确定部署的优选方案,为规划我国根镜像服务器引入部署提供新思路。

Abstract: With the rapid development of the internet, it has become a trend to increase the number of root server instances.Therefore, a scientific and reasonable theory were put forward to provide a reference for the introduction and deployment of root server instances in China.Firstly, combining with the actual situation of root server instances deployment in China at present, the overall introduction deployment strategy was given.Then the number and type of
the root server instances were suggested through data analysis.Then, by means of detection or collection, we obtained root parse data, recursive parse service data and internet development data in China, and obtained the recommended provinces and operator networks for root server instances deployment by the normalized weighted calculation model.At last, some suggestions on the supervision of root server instances were given from the aspects of system and technology.The results showed that the optimal deployment scheme could be determined by scientific means, which provided a new idea for planning the deployment of root server instances in China.
