Troubleshooting with Network Analyzer

מק"ט: #882 | משך קורס: 24 שעות אק'

A Network Analyzer (also known as a network analyzer or protocol analyzer or, for particular types of networks, an Ethernet Network Analyzer or wireless Network Analyzer) is computer software or computer hardware that can intercept and log traffic passing over a digital network or part of a network. As data streams travel back and forth over the network, the Network Analyzer captures each packet and eventually decodes and analyzes its content according to the appropriate RFC or other specifications.
The course goal is to give the student the ability of understanding the Network Analyzer tools the protocols family and the troubleshooting among the 7 networking layer.
The course will be demonstrated and operated on Ethereal freeware Network Analyzer.
