QualNet 7.1

QualNet is a high-fidelity, scalable network simulation and emulation platform used to design, analyze, and predict the performance of wired, wireless, and mixed networks. It supports large scenarios with repeatable results, helping teams evaluate architectures and protocols before deployment.

Key capabilities:

• Discrete‑event simulation engine with models for IPv4/IPv6, TCP/UDP, QoS, Wi‑Fi (IEEE 802.11), LTE, multicast, and common MANET routing protocols (such as AODV, DSR, and OLSR)
• Detailed radio and terrain modeling, including path loss, shadowing, fading, antenna patterns, mobility, and energy/battery effects
• Graphical scenario design, animation/visualization, packet tracing, and comprehensive statistics export
• Parallel execution on multi-core and clustered systems to handle thousands of nodes efficiently
• Extensible C/C++ APIs for custom protocol development and integration, with options for emulation and co-simulation for hardware- or software-in-the-loop workflows
• Typical use cases include research, network planning, training, and operational support across defense, public safety, IoT, vehicular, and enterprise environments
• Available for Windows and Linux systems
