NetSim Workflow

Design the network

Design

Create network scenarios using NetSim's GUI or using XML config files
Click and Drop devices, links, application etc into the environment using NetSim's GUI
Set properties with just a click. Layer-wise parameters can be edited
Model large and complicated networks using the XML config file which comes with automatic verification

Run the Simulation

Run

Run the discrete event simulation (DES) through the GUI or via Command Line Interface (CLI)
Log packet traces that reports parameters such as arrival time, queuing time, payload, overhead, error etc for every packet as it flows through the network
Record event traces which logs every single event in the protocol Finite State Machine (FSM) transitions along with associated information like time-stamp, Event ID, Event Type etc.

Visualize the simulation - Packet Animator

Visulize

Animate packet flow over wired and wireless links
Color variation for control packets, data packets and error packets
Control animation with play, pause and simulation time line

Analyze the results

Analyze

Examine output performance metrics at multiple levels - network, sub network, link, queue, application etc.
Study a variety of metrics such as throughput, delay, loss, packet error, link utilization... etc.
Interpret metrics using in-built plots and graphs
Export packet and event trace files easily to tools like Excel, Notepad etc for post-processing and statistical analysis

Develop your own protocol / algorithm

Develop

Extend existing algorithms by modifying NetSim's source C code
Create custom protocols using NetSim's simulation API's
Interface with other software products
Debug your code (step-in, step-out, step-over, continue) and watch your variables in sync with simulation

Interface with external software

Interface

The external interface allows NetSim to pass the instantaneous network data to an another tool like MATLAB, SUMO etc
Software program can then run its compute engine and send back information to NetSim
NetSim will then use this output to carry out its network simulation routines
