Introduction:
 
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..
 
Audience:
 
Those designing, architecting, supporting, and planning QoS-aware multimedia wireless and wireline etworks with an emphasis on the networks based on the Internet Protocol (IP).
 
Prerequisites:
 
Solid understanding of circuit, cell and packet networking concepts and protocols, broadband etworking, Quality of Service (QoS) and Quality of Experience (QoE), and at least two years experience designing and implementing networks
 
Customize it:
 
This 3-4-day Traffic Engineering of QoS-Aware Multimedia Networks: Access and Backbone course will be customized to your needs and specifications. Eno.com will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of telecommunication training. They will typically have a broad and general course, one size fits all, already developed and just put your organization?s name on the title slide. This minimizes their effort and time investment. At Eno.com, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren't too sure of what that was. We fit the class to your needs. We never fit you into our standard, one size fits all, class. Please call or e-mail to schedule a no-obligation conference call to help us understand your audience background and training objectives.

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.
