HSCP： a hardware and software combined platform to improve precision in active network measurement

In this paper, an active network measurement platform is proposed which is a combination of hardware and software. Its innovation lies in the high performance of hardware combined with features that the software is easy to program, which retains software flexibility at the same time. By improving the precision of packet timestamp programmable hardware equipment, it provides packet sending control more accurately and supports the microsecond packet interval. We have implemented a model on the NetMagic platform, and done some experiments to analyze the accuracy difference of the user, the kernel and hardware timestamp.
