面向富互联网应用的数据传输策略研究

摘要

针对富互联网应用系统需要传输较大数据量而导致速度慢这一问题,研究了一种基于上下文感知的数据传输策略,通过感知用户的浏览记录和当前行为,系统可以自动预测用户下一步对数据的需求,并充分利用用户交互过程中的网络空闲时间传输数据,以提高系统的响应性.实验结果表明,该数据传输策略大大缩短了用户的等待时间,特别是在比较复杂的场景中,效果更为显著.%For the problem that rich internet application (RIA) needs to transfer a large amount of data a data transmission strategy based on context-aware is studied. By sensing the users' browsing history and current behavior, the system can automatically predict the data needs for the next step, and make full use of the network idle time during the process of users' interaction to transfer data, so as to improve system responsiveness. The experimental results show that the data transmission strategy can greatly reduce users' waiting time, especially in more complex scenarios, the effect is more significant.
