Contribution

It introduces a novel integration of packetdrill into INET, facilitating protocol testing in a simulation environment for the first time.

Findings

Enables detailed protocol testing within OMNeT++

Supports injection and verification of packets at specific times

Provides a new tool for protocol development and validation

Abstract

Google released in 2013 a script-based tool called packetdrill, which allows to test transport protocols like UDP and TCP on Linux and BSD-based operating systems. The scripts defining a test-case allow to inject packets to the implementation under test, perform operations at the API controlling the transport protocol and verify the sending of packets, all at specified times. This paper describes a port of packetdrill to the INET framework for the OMNeT++ simulation environment providing a simple and powerful method of testing the transport protocols implemented in INET.
