One-way loss measurements from IPFIX records
Ricciato, Fabio; Strohmeier, Felix; Dorfinger, Peter; Coluccia, Angelo (2011): One-way loss measurements from IPFIX records In: Measurements and Networking Proceedings (M&N), 2011 IEEE International Workshop on Measurement and Networking, Anacapri, Italy.
In this work we describe a methodology to estimate one-way packet loss from IPFIX or NetFlow flow records collected at two monitoring points. The proposed method does not require tight synchronization between the two monitoring points, nor it relies upon external routing information. It can run online or offline, and can work on legacy IPFIX/NetFlow traces which were not collected for the specific purpose of loss estimation. In this preliminary work we describe the estimation procedure and present early validation results from a real testbed.
