一种基于域名分片的地图瓦片快速加载方法研究

Research on a method of faster loading map tiles based on domain sharding

地图瓦片是通过对地图采用分级切片方式以提高地图加载效率的一种重要技术方法,在一些主流的地图平台已得到了广泛应用。随着电脑显示器屏幕分辨率的提高和地图数据内容的增加,在浏览地图过程中加载的地图瓦片数量也随之大量增加。针对地图瓦片数量激增与浏览器并发限制的矛盾,研究基于域名分片技术提升地图瓦片加载效率的方法,并设计了实验方案,对浏览器在HTTP/1.1、HTTP/2.0协议下分别使用域名分片方式加载地图进行了对比分析。

Map tile is an important technological method to improve the efficiency of map loading by slicing and grading the map.It has been widely used in mainstream map platforms.With the screen resolution improving and the map content increasing,the number of map tiles while browsing the map has also increased obviously.Aimed at the problem between many map tiles explosion and concurrent connections of browser,the experimental plan was designed in the research on a method of faster loading map tiles based on domain sharding,and it conducted the comparative analysis on the browser of loading map tiles in the separate use of domain sharding by HTTP/1.1 and HTTP/2.0 protocols.
