Multi-nodes Traffic Replay Method based on IP-mapping

摘要

Traffic replay is a common method in traffic generation applied to the construction of network cyber ranges. At present, the implementation of replaying traffic within cyber ranges is one client one server or multi-nodes one-way communication, the effect is inferior. Therefore, this paper proposes a multi-nodes traffic replay method to solve high replay delay error during interactive replay in small scale. Based on this method, an IP-mapping method is designed to solve the problem of large file allocation in multiple machines. Experiments showed this method can support multi-nodes traffic replay, and replay delay error is significantly lower than Tcpreplay.
