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.
WHY NETSIM? Communication Networks have become too complex for traditional analytical methods or “rules of thumb” to provide an accurate understanding of system behavior and possible problems and solutions.
MODELING AND SIMULATION Building the model hh Create network scenarios using NetSim’s GUI or using XML config files hh Click and Drop devices, links, application etc into the environment using NetSim’s GUI hh Set properties with just a click. Layer-wise parameters can be edited
Running the simulation hh Run the discrete event simulation (DES) through the GUI or via Command line interface (CLI) hh 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 hh Capture packets using Wireshark hh Record event traces which logs every single event in the protocol finite state machine (FSM) transitions
Graphical User Interface
Visualizing the simulation using the packet animator hh Animate packet flow over wired and wireless links hh Color variation for control packets, data packets and error packets hh Control animation with play, pause and simulation timeline
Analyzing the results hh Examine output performance metrics at multiple levels - network, sub network, link, queue, application etc hh Study a variety of metrics such as throughput, delay, loss, packet error, link utilization ... etc hh Interpret metrics using in-built plots and graphs hh Export packet and event trace files easily to tools like Excel, etc for statistical analysis
Packet Animator
Developing your own protocol / algorithm hh Extend existing algorithms by modifying NetSim’s source C code hh Create custom protocols using NetSim’s simulation API’s hh Interface with other software products hh Debug your code (step-in, step-out, step-over, continue) and watch your variables in sync with simulation Write Your Own Code

NETWORK PROGRAMMING EXCERCISES (FOR EDUCATION CUSTOMERS) 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, 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. Practice Mode and Exam Mode: Facilitates easy assessment since professors, can create user accounts for each student, and set them in practice mode or exam mode. Practice mode corresponds to regular lab sessions and where supporting help is available for a smooth learning curve. In exam mode all help is turned off and NetSim can be used as an assessment tool to check if user code is correct.
