移动即时通讯软件的缓存替换策略
TP302; 近年来，移动即时通讯软件功能越来越多样化，其聊天记录等数据的规模也越来越大，这给本身空间有限的移动终端的存储和处理带来很大压力。为了解决以上问题，研究和分析了移动即时通讯软件中针对不同部分的聊天记录用户的行为特点，进而探究了用户行为和缓存价值之间的联系，提出了一种基于用户浏览行为的缓存替换策略，针对每部分缓存的数据对用户的价值有选择地替换记录缓存。该策略可以很好地适应移动终端小内存、低带宽和即时通讯软件高时效性等要求。实验证明，所提策略具有较高的缓存命中率，且可有效控制即时通讯软件的缓存大小。...

| Abstract_FL | Recently, the function of mobile instant messaging application is becoming more and more complex, mean-while, the size of data recordings is also becoming bigger and bigger. As a consequence, this situation has brought great pressure to the limited space of mobile terminals. To cope with the above problem, this paper studies and analyzes different user gesture on different parts of the mobile instant messaging application, and then explores the relation between user gesture and the value of cache blocks. This paper also proposes a strategy based on user gesture to manage the cache of mobile instant messaging application accordingly, and points at the value of each block of cache data for user replacing cache blocks. This strategy is capable of adapting to the characteristics of mobile termi-nals with relatively small memory, low bandwidth and high timeliness requirements of instant messaging software.Through the experiments, the proposed strategy has high hit rate and can hold the cache size of mobile instant messaging application. |
