延迟满足特性在流媒体中的应用研究

在流媒体应用中引入了心理学中延迟满足的概念。结合流媒体应用中用户的操作行为之间的关系，研究了在流媒体应用中存在的延迟满足问题。并基于延迟满足的特性，利用不同用户的延迟满足特性的个体差异，提出了基于延迟满足的资源调度策略。仿真结果表明，该调度策略与传统的先进先出调度策略相比较，增加了所请求流媒体数据的播放概率，从而降低了带宽资源浪费。

Research of feature about delay of gratification in streaming applications

The psychology feature about delay of gratification is introduced in streaming application.With the relations of user behaviors in streaming application,the delay of gratification in streaming is studied in details.Then a novel resource scheduling strategy is proposed,which uses the individual differences in delay of gratification.The simulation results show that the strategy proposed in this paper is superior to FIFO,because it increases the probability of the requested streaming data to be played,which leads to the decrease of bandwidth wasted.
