Process for Sub-Second Resolution in Packet Capture Assessments

Abstract

These are some notes, and links on my research for verifying a network packet capture workflow, and determining if that was supporting nanosecond timestamps.

My conclusion is that while Sub-Second resolution is possible in network packet capture analysis; and a nanosecond is equal to 1000 picoseconds or 11000 of a microsecond, and it should be remembered that this does not guarantee that your source packets are stamped with this accuracy. This article examines the requirements for this accuracy, and why properly understanding this can lead to more accurate assessments of network performance of applications, whether nanosecond packet captures are taken or not.
