High-Bandwidth Tactical-Network Data Analysis in a High-Performance-Computing (HPC) Environment: Time Tagging the Data

Abstract

The analysis of data from radio-based network testing typically requires that the latency of data leaving one node and arriving at a destination be determined. To properly calculate latency, transmit and receive times of network packets must be measured, and those times must be synchronized to a common source. The Global Positioning System (GPS) is a readily available time source that can be made available at each of the distributed nodes in a network. However, applying GPS-synchronized time tags to recorded network packets has proven to be a challenge due to microsecond drift, data stream buffering, and other technical issues. The process described in this report made use of post-test processing techniques to provide packet-level time tagging with an accuracy close to 3 microsecs relative to Coordinated Universal Time, with a resolution of 1 microsecs. This enabled analysis of high-speed wireless networks where a medium-sized packet can be delivered in under 1 ms.
