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.
