摘要
文章从解决系统资源占用率与页面新鲜度之间的矛盾出发,构建了搜索引擎系统中页面更新子系统的三层模块结构,并在此基础上提出了一种非对称页面更新算法。模拟试验表明,该结构和算法能够有效地节约系统资源,提高页面的新鲜度,并且具有良好的可适应性。
In this paper, a three-layer architecture of page refreshing module in search engines is discussed and an asymmetry page refreshing algorithm is put forward in order to avoid the conflict between limited system resources and demand of page information freshness. Simulation tests show that such architecture and algorithm can improve page information freshness while saving resources. Furthermore, they are excellent in adaptability.
