EstiNet Network Simulator: A Powerful Tool for Network Research and Education

Network simulation is a widely used technique for studying and testing various network protocols, applications, and scenarios. Network simulation can help researchers and educators to evaluate the performance, reliability, and security of network systems without the need of deploying real hardware and software.

However, not all network simulators are created equal. Some network simulators may have limitations in terms of scalability, accuracy, realism, or usability. Therefore, choosing a suitable network simulator is an important decision for network researchers and educators.

In this article, we will introduce EstiNet Network Simulator, a Linux container-based time control simulator platform that integrates real-world high-quality core network software modules with a realistic radio access network (RAN) simulator and user equipment (UE) simulator. We will show how EstiNet Network Simulator can support various network research and education topics, such as 5G network simulation, wireless vehicular communication network simulation, network emulation, and more.

EstiNet Network Simulator Features

EstiNet Network Simulator is a powerful tool that offers many features and benefits for network research and education. Some of the main features of EstiNet Network Simulator are:

Use real-world protocol stacks: EstiNet Network Simulator integrates Linux kernels TCP/IP and UDP/IP protocol stacks to provide real layer-3 and layer-4 protocol behavior for network applications.

Support real-world Linux network applications: EstiNet Network Simulator allows Linux-based network application programs, that can be run upon a real Linux network device, to be directly run upon a simulated network device. This helps to develop and test applications functionalities in simulated networks. It also helps to use real network applications to test newly-invented or modified lower-layer protocols and mechanisms.

Interact with real-world network devices: EstiNet Network Simulator can turn into an emulator that builds a testing network field consisting of physical and virtual devices. The software functionalities of a physical device can be developed and tested in the testing field.

Support various network devices and protocols: EstiNet Network Simulator supports common wired and wireless network devices such as hub, switch, router, host, IEEE 802.11(a/g/n) ad hoc mode and infrastructure mode. EstiNet Network Simulator also supports VANET (IEEE 802.11(p), ITS) and OpenFlow.

Provide a friendly GUI environment: EstiNet Network Simulator provides a highly-integrated and professional GUI environment in which a user can easily create network topologies, edit node properties, run simulations, and review simulation results in the animation playback mode.

Provide high accuracy, quickness, repetition, and scalability: EstiNet Network Simulator is based on a kernel-reentering simulation methodology that allows researchers to test their applications with high accuracy, quickness, repetition, and scalability.

EstiNet Network Simulator Applications

EstiNet Network Simulator can be used for various network research and education topics, such as:

5G network simulation: EstiNet Network Simulator can support overall 5G network simulation by integrating real-world high-quality core network software modules with a realistic radio access network (RAN) simulator and user equipment (UE) simulator. It can provide a complete 5G research platform on protocol-layer RAN + UE module with core network software.

OpenFlow network simulation and emulation: EstiNet Network Simulator can support testing the functions and evaluating the performances of software-defined networks (SDN) OpenFlow controllers application programs. EstiNet uses an unique kernel reentering simulation methodology to enable unmodified real applications to run on nodes in its simulated network. As a result, without any modification, real NOX/POX or Floodlight OpenFlow controllers can readily run on a host in an EstiNet simulated network to control thousands of simulated OpenFlow switches.

VANET simulation: EstiNet Network Simulator can support wireless vehicular communication network simulation by providing IEEE 802.11(p) and ITS protocols and devices. EstiNet also provides realistic channel models, traffic flow classification for QoS, and network traffic generators for VANET simulation .

EstiNet Network Simulator Comparison

EstiNet Network Simulator can be compared with other network simulators and emulators, such as ns-3, Mininet, and OMNeT++. In this section, we will briefly compare EstiNet Network Simulator with Mininet, which is a popular OpenFlow network emulator.

Mininet is an OpenFlow network emulator that creates a virtual network of hosts, switches, controllers, and links on a single Linux kernel. Mininet uses lightweight virtualization to make a single system look like a complete network. Mininet can run real-world OpenFlow controllers and applications on its emulated network.

EstiNet Network Simulator can also run real-world OpenFlow controllers and applications on its simulated or emulated network. However, EstiNet Network Simulator has some advantages over Mininet in terms of correctness, performance, and scalability.

Correctness: EstiNet Network Simulator uses a kernel reentering simulation methodology that ensures the correctness and repeatability of the simulated results. EstiNet Network Simulator can accurately measure the average round-trip time (RTT) of ping packets over different network sizes. Mininet, on the other hand, may generate strange results that cannot be explained over some network sizes.

Performance: EstiNet Network Simulator can run simulations or emulations faster than Mininet. EstiNet Network Simulator spends less time on its program launch, network setup, and resource releasing when the network size is large. Mininet may spend a huge amount of time on these tasks when the network size is large.

Scalability: EstiNet Network Simulator can support larger network sizes than Mininet. EstiNet Network Simulator can run simulations or emulations over a set of N N grid networks, where N = 5, 6, ..., 31. Mininet may encounter memory errors or system crashes when the network size is larger than 15 15.

EstiNet Network Simulator Conclusion

EstiNet Network Simulator is a powerful tool for network research and education. It can support various network topics, such as 5G network simulation, OpenFlow network simulation and emulation, and VANET simulation. It can also run real-world protocol stacks, network applications, and OpenFlow controllers on its simulated or emulated network. EstiNet Network Simulator has the advantages of correctness, performance, and scalability over other network simulators and emulators. EstiNet Network Simulator is a Linux container-based time control simulator platform that integrates real-world high-quality core network software modules with a realistic radio access network (RAN) simulator and user equipment (UE) simulator.
