In this paper, we introduce an interactive Internet traffic replay tool, TCPopera. TCPopera tries to accomplish two primary goals: (1) replaying TCP connections in a stateful manner, and (2) supporting traffic models for trace manipulation. To achieve these goals, TCPopera emulates a TCP protocol stack and replays trace records interactively in terms of TCP connection-level and IP flow-level parameters. Due to the stateful emulation of TCP connections, it ensures no ghost packet generation which is a critical feature for live test environments where the accuracy of protocol semantics are of fundamental importance. In our validation tests, we showed that TCPopera successfully reproduces trace records in terms of a set of traffic parameters. Also we demonstrated how TCPopera can be deployed in test environments for intrusion detection and prevention systems.
