EstiNet 5G Network Simulator and Emulator


The EstiNet network simulator/emulator originates from NCTUns. NCTUns had been used for network-related research and publication from 2002 to 2011. It became a commercial software on 2011 and was renamed EstiNet. EstiNet’s network simulation environment includes physical layer, media access control layer, network layer, transportation layer and application layer. In addition, EstiNet’s user-friendly GUI provides users a convenient way to construct a simulated network and a visual display for simulation result observation and debugging.

EstiNet11 supports 5G network simulation by providing a complete 5GC software and abstract RAN+UE modules that simulates simplified RAN attributes and UE behaviors. It integrates high-quality 5G core network software developed by free5GC alliance initiated by National Chiao Tung University, Taiwan. The 5G network simulation of EstiNet is accomplished using pure software and thus it can be installed and executed on pure cloud systems.

Visualization of Network Communication

EstiNet11 can intuitively display visual animation of layer-2 frame transmission/reception/floating over media. For 5G simulation, EstiNet11 further provide message-level animation to display control message exchanges among 5GC components, which is useful and helpful for learning and studying 5G core network behaviors. (The 5G message-level animation feature is coming soon.)

Integrate Linux kernel’s protocol stacks

Linux kernel’s TCP/IP & UDP/IP protocol stacks are directly integrated in simulated networks to provide real layer-3 and layer-4 protocol behavior for network applications.

Compatible with real-world Linux network applications

Linux-based application programs, which are usually executed on real Linux-based machine, can be directly run onto simulated nodes of EstiNet11. The capability of executing real programs means that real-world network behaviors can be exactly reflected in EstiNet11’s simulated network. This feature is useful to develop and test the functionalities and performance of a new application by using EstiNet11. It is also useful when testing a newly developed network by using EstiNet11 and real-life network applications.

Interact with real-world network devices

EstiNet11 can turn itself from the simulation mode to the emulation mode. When turning into the emulation mode, a simulated network/device can transmit/receive packets to/from a real-world device. That is, an emulated network comprises simulated network nodes and real network devices. This mode is useful to test the behavior of a newly developed network equipment.
