| Research Abstract |
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.
