Day 3: Hands-On Traffic Engineering

Automated network design and traffic engineering tools will be used in a “real world” scenario to model and simulate a multimedia IP network. The exercise will allow the participants to experiment on their own and run “what-if” type scenarios optimizing different aspects of network performance influenced by traffic engineering. Periodic milestones will be marked by group lab debriefs during which participants will share their ongoing progress. There are three levels of Hands-On Traffic Engineering labs geared to the experience and knowledge level of the learner. All learners will have a common debrief regardless of the level of difficulty of their lab exercise.

Course Overview

Course in a Nutshell

This course includes an intensive two-day long tutorial followed by a full day of workshop activity. You will begin by understanding the key concepts and techniques of traffic engineering. You will then learn to apply those techniques to the traffic engineering of QoS-aware multimedia networks. We will conclude with a day of exercises using actual network simulation tools. The exercises will be carefully chosen to reinforce what you learned in the first two days of the course.
To be able to participate in the hands-on activities, please bring a wireless-enabled laptop to the class. If using a company computer, please make sure beforehand that you have full administrative rights to install new software on the computer. The course relies heavily on instructor/class interaction and lab exercises to make sure that you get the most out of this class and can apply the material back on your job. So come prepared to ask questions and dig into the discussions and labs.


Customize It!

Customize this course to your exact requirements at little to no added cost. We can adjust the topics and level of details to suit your audience. Without the hands-on lab portion, the class can be shortened to two days. We can also expand the workshop to two days, for a four-day long course.
