Thus it is as-if the real packet flowed through a real network but in reality it flowed through the simulated network. Network emulation allows users to introduce real devices and applications into a test network simulated that alters packet flow in such a way as to mimic the behavior of a live network.

This page was last edited on 8 Septemberat Effects of various radio resource management and quality of service QoS schemes on higher-layer protocols and real-world applications can be easily studied using NCTUns.

Wiley Telecommunications network Networking hardware Mesh networking Hoc programming language Internet protocol suite.

The typical methodology is that real packets from a live application are sent to the emulation server where the virtual network is simulated. There are a wide variety of network simulators, ranging from the very simple to the very complex.

Since communication networks have become too complex for traditional analytical methods to provide an accurate understanding of system behavior, network simulators are used. Most network simulators use discrete event simulationin which a list of pending "events" is stored, and those events are processed in order, with some events triggering future events—such as the event of the arrival of a packet at one node triggering the event of the arrival of that packet at a downstream node.

In simulators, the computer emulayor is modeled with devices,links, applications etc. In this paper, we elaborate on NCTUns simulation methodology, architecture, design, functionalities, performance, and applications.

Output results would include network level metrics, link metrics, device metrics etc. Live traffic can pass through the simulator and be affected by objects within the simulation. Further, drill down in terms of simulations trace files would also be available.

In computer network research, network simulation is a technique whereby a software program models the behavior of a network by calculating the interaction between the different network entities routers, switches, nodes, access points, links etc.
