The testing of stateful network devices at near wire-speed operation is accomplished by a tester that delivers realistic client-side and the server-side traffic to stateful network device under test, where the realistic traffic can simulate legal packets of a plurality of TCP sessions that are expected to be transferred over each connection between the tester and the device under test. The simulated traffic in a session is independent of previous states of the session or received packets. The packets are generated by the tester based on a predefined scenario. The scenario can define the type of the session (http, ftp, email, any combination of those, etc.) the content, the size of a message, number of connections in the session, missing packets, bit rates, etc. For each scenario, one or more scripts can be created. The scripts can simulate problems so that the operation of the device under test can be monitored.
