Benchmark Electronic Systems offers three NETWORK LABORATORY configurations based on the LAN-T LAN trainer and i-SECURIT Network & Data Security System.

The LAN-T – a patent pending product – jointly developed with IIT Madras, is being widely used, for the last 15 years, by customers worldwide, to teach network protocols and their behavior. i-SECURIT, jointly developed with AU-KBC Research Centre, ANNA University, is the best solution to impart education in network security and data protection techniques.

The Benchmark Network Laboratory is a full featured lab system that covers important topics in computer networks such as protocols behaviour under various conditions, socket communication techniques and cryptography and network security.  It emulates a real life environment to give a complete feedback to users on each topic.  Since, in most of the experiment topics, data passes in real time, it undergoes changes because of errors, impact of speed on protocol, distance between nodes etc., thereby giving realistic results. The three configurations offered are:

1/ Benchmark Network Lab 1
2/ Benchmark Network Lab 2
3/ Benchmark Network Lab 3

The Benchmark Network Lab 1

Supports 5 groups of 15 students

The Benchmark Network Lab 1 comprises a LAN-T which consists of a Network Emulator Unit (NEU) which acts as a physical layer; three Network Interface Cards or Units (NIU) with each NIU card emulating two nodes in a single PC and acting as MAC & LLC layers; experimentation software with the source code and C library. Each LanT emulates a network of 6 nodes with just three computers.

The Benchmark Network Lab 3

Supports 5 groups of 15 students

The Benchmark Network Lab 3 comprises a LAN-T and a i-SECURIT. The LAN-T consists of a Network Emulator Unit (NEU) which acts as a physical layer; three Network Interface Cards or Units (NIU) with each NIU card emulating two nodes in a single PC and acting as MAC & LLC layers; experimentation software with the source code and C library. Each LanT emulates a network of 6 nodes with just three computers.

The i-SECURIT consists of a Central Control Unit with 15 user log-ins. It provides a complete study of all Data Encryption & Decryption Algorithms (Cryptography), Malware Tools, Web Services using Cryptography Techniques, Network / System Threats, Web Vulnerabilities, Network Identification. In addition, it also offers a Mailer Application to understand the importance of Cryptography as well as Socket Programming in Linux on Select Crypto-Algorithms like RC4, RSA and 3-DES, Enumeration, Packet Sniffer, Virus & AV Tools and SQL Injection. Above all, it has a built-in Courseware with step by step procedures.
