Network Design using GNS3

About the Course

A practical-oriented hands-on course for designing computer networks (LAN,WAN etc) using GNS3 (open source network designing software)

Course Objectives(What will you learn)

To design and analyze simple computer networks; to troubleshoot networks using packet analysis; to study the feasibility of interconnecting different types of network elements with the following outcomes: (a) Design and configure networks using different types of network elements, (b) Analyze the packets exchanged between the network elements

Who should attend

Students with knowledge of computer networks are preferred. Knowledge of Wireshark is desired.

Out station students / candidates have to make their arrangements for accommodation and boarding
