The paper describes a method of tracking individual IP packets throughout the network from their creation to delivery. The method keeps tracking various events including fragmentation, tunneling and NAT. An experiment with a software implementation of the method is described. Possible applications of the method include troubleshooting and studying of computer networks.

The paper discusses a method of retrieving detailed information on IP packet processing in Linux operating system. Modifications to Linux networking subsystem source code are described, along with the architecture of a monitoring tool based on the method being discussed. An example of the monitoring tool output is provided.  Possible applications of the method include troubleshooting and studying computer networks.
