Development of a precise software packet scheduling mechanism

本研究的目的是开发一种新的基于软件的精确而灵活的调度机制，以保证数据在高速网络上的传输性能。所提出的机制通过传输的字节数来确定分组的传输定时，以实现精确的分组调度，而不依赖于硬件定时器。我们展示了两种实现方式的优缺点：基于GAP包的实现和基于高精度计时器的实现。我们还报告说，它在一项商业音乐数据传输服务中运行稳定。

The aim of this study is development of a new software-based precise and flexible scheduling mechanism to guarantee the data transmission performance on high-speed networks. The proposed mechanism determines transmission timing of packets by the number of bytes transferred to enable a precise packet scheduling without dependence on a hardware timer. We show the pros and cons of two types of implementations : a gap packet based and a high-resolution timer based. We also report it has been in stable operation on a commercial music data delivery service.
