Objectives

This course is designed to give students a structured theoretical basis on the subject of Network Management. In addition, it will transmit experimental knowledge aquired through the operation of large IP networks. Contents include discussions regarding the alternatives of open source tools available, and the opportunity to install and operate a number of them.

Pre-requisites

Familiarity with the GNU/Linux operating system. Understanding of TCP/IP and Ethernet protocols.
