GNERAL DESCRIPTION Networking Study Software is developed to provide basic understanding and implementation of various fundamental and advanced concepts on networking in Real Time and under simulation. The software provides an opportunity to understand network fundamental through animation. The simulation provides network experimentation with various LAN & Wireless Protocols. Vi-RtSim also includes programming exercises for students to get hands on practice on networking parameters. All networking theory is explained using simulation and animation.

Vi-RtSim

Vi-RtSim Can provide the following

* An opportunity to understand networking concept * Includes programming exercises using Script language * Performance Analysis of various network methodology with EXCEL

* Includes Simulation for network experiments with various LAN, Wireless

LAN, and LAN Protocols * Includes Real time Packet capture * Provides Real Time Interface with various hardware LAN trainer ViLAN-01, ViLAN-01A, ViLAN-02 & ViLAN-03. * Provision to toggle between simulation and real time performance of

hardware LAN trainer for many experiments.

PC1 is connected to NIC1 card, PC2 is connected to NIC2 card and PC3 is connected to NIC3 card. Additionally PC4 can also be connected to access NIC1, NIC2 and NIC3. Or, These PCs can be randomly connected to each NIC card. This Means PC4 can be connected to NIC1, PC3 can be connected to NIC2 and PC 1 can be Connected to NIC3. Each NIC card has it own Ethernet Connectivity. Inside the Emulator Unit has one Switching device (HUB),where three NIC card is connected Internally. For an External Connectivity (To PCs -PC1,PC2,PC3 & PC4) , four RJ-45 connector is provided.
