一种新的多路媒体流复用调度算法

文中针对多路媒体流的调度问题,在分析经典的缓冲区反馈控制算法和按DTS调度算法基础上,提出了一种基于权重的调度算法,该算法对各路媒体流均动态分配权重,调度前比较各路媒体流的权重,每次选择权重最大的媒体流进行调度,它吸取了其它多路媒体流调度算法的优点,并充分考虑了多路媒体流调度的优先级问题。试验结果表明该算法是切实可行的和有效的。

An Novel Scheduler Algorithm of Multiplex Media Streams

Focusing on the scheduling of multiple media streams, a new weight based scheduler algorithm is presented. The author, based on a term study of some classic algorithms, including the algorithm based on the feedback from buffer area, and the algorithm based on DTS scheduling, proposes this new algorithm. This algorithm implements the assignment of dynamic weight to each media stream, compares the weight of each media stream before scheduling, and always schedules the first priority. It absorbs the merits of other scheduling algorithms on multiplex media stream, adds the assignment on priority. Experiment result proves that this algorithm is feasible and effective.
