Original Abstract

Precise timestamps assigned to individual packets play an important role for network traffic analysis and measurement of network infrastructure. Moreover, connection of precise timestamps with flow based analysis, allow us to measure quality of end to end and other QoS-oriented applications. This technical report describes a hardware module for precise timestamp generation dedicated for flow monitoring probe - FlowMon. It shows hardware architecture of the module, measurement of timestamp accuracy and discussion about possible use cases in flow based applications.
