Why NetSim?

NetSim is a leading network simulation software for protocol modeling and simulation, network R & D and defence applications. It allows you to analyze computer networks with unmatched depth, power and flexibility.

How NetSim is used?

Design the network

▪ 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

▪ Run the Discrete Event Simulation (DES) through the GUI or CLI

▪ Log packet trace and event trace files ▪ Capture packets using Wireshark

Run the simulation

▪ Animate packet flow over wired and wireless links

▪ Colour variation for control packets, data packets and error packets

▪ Control animation with play, pause and simulation time-line

Visualize the simulation - packet animator

▪ 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 ▪ Create pivot tables and charts for visualization

▪ MATLAB ▪ SUMO ▪ WIRESHARK

▪ Extend existing algorithms by modifying NetSim’s source C code

▪ Create custom protocols using NetSim’s simulation API’s

▪ Debug your code (step-in, step-out, step-over, continue) and watch your variables in sync with simulation

Interface with external software Develop your own protocol / algorithm

How do I connect real devices to NetSim ?

Emulator Features

• Can be scaled to hundreds of nodes in the network in between• Facilitates multi-tenancy, which means there can be multiple sources / destinations or clients / servers

connected to the emulator

NetSim emulator provides critical insights into application performance by enabling user to run their live application over an equivalent virtual network and see how the application is performing in real time. It also assists networking teams to make informed decisions across the entire application life-cycle, help building “what-if” scenarios to choose between different network technologies and adjust application settings to optimize performance.

NetSim Emulator can interface with the following technology libraries

• Internetworks • BGP Networks• Cognitive Radio Networks • LTE Networks• MANET Networks • Wi-Max Networks

NetSim Emulator enables communication between real devices over a simulated network

Network programming is a key skill that enhances student’s “employability”. Apart from simulation, NetSim features a separate “Programming” menu to help students build skills in these basic mechanisms of computer networking. Graphical Representation: Features a custom built UI, for each exercise. This custom UI explains the working of the technology with animation per code progress. When the user links his or her code then the graphs change per the output of the user’s code.

Breadth of Techniques - Covers over 45 exercises including:

▪ Address Resolution Protocol ▪ Assignment of Sites to Concentrator ▪ Cryptography - DES,RSA, Transposition, Substitution, XOR,WEP

▪ Distance Vector Routing ▪ Dynamic Host Configuration Protocol ▪ Error Correcting Code - Hamming Code ▪ Error Detection Code - CRC 12, CRC 16, CRC 32, CRC CCITT, LRC

▪ Framing Sequence - Bit Stuffing, Character Stuffing

▪ Generic Cell Rate Algorithm - Virtual Scheduling Algorithm

▪ IPv4 Addressing - Address Mask, Binary Conversion, CIDR, Network Address, Special Address, Subnetting

▪ IPv6 Addressing - EUI-64 Interface Identifier, Host Addresses, Subnetting

▪ Leaky Bucket Algorithm ▪ Multi-Level Multi-Access collision free protocol ▪ Multiple Access Technology - CDMA, TDMA, OFDMA

▪ PC to PC Communication - Socket Programming, Chat Application

▪ Scheduling - MMF, FIFO ▪ Shortest Path - Link state routing, Floyd’s algorithm

▪ Sliding Window Protocol - Go Back N, Selective Repeat

▪ Sorting Techniques - Bubble, Insert, Quick, Select

▪ Spanning Tree - Kruskal, Prims, Borovska ▪ Transmission Flow Control - Stop and Wait, Selective Repeat, Go Back N

Algorithm, Flow Chart, Pseudo Code & Source Code: Enables the student to get familiar with software design principles, interface guidelines and implementing network programs. They provide a step-by-step understanding of network programming.

▪ Provided along with all exercises are working C source code for the faculty.

▪ Codes are standard C and compile with GCC ▪ Programs contain standard API’s and code separation into source and header files

▪ I/O interface via text files

De-bugging: Simplifies de-bugging as users can link their code to NetSim using “Attach to process” and passing NetSim’s install path and windows temp folder as command line arguments. Then users can add break points in their code and proceed with de-bug with step-in, step-out, step-through etc.
