摘要 非对称通信环境下,服务器数据广播是一种比较实用的技术,而其移动客户端cache的管理,由于移动环境的限制,传统的LRU算法和理想的LIX算法都存在缺陷。提出了一种基于历史访问记录的数据替换算法。其中,无向概率图上的筛选过程,算法简单,复杂度小。试验表明,此算法明显改善了cache命中率和平均响应时间。 Under asymmetric communications environments, data broadcast is a kind of useful technology; however, both traditional LRU algorithm and ideal LIX algorithm have limitation in mobile networks. A kind of replace algorithm is introduced based on accessing histories. Experiment indicates that the algorithm greatly improves cache hit rate and average response time.
