Introduction:
 
Good traffic engineering is important not only in the initial design of a voice or data network but also key to its continued smooth operation. This two-to-three day course provides a sound introduction to the principles of traffic engineering, the exact duration depending on the number and types of transport technologies and services included in the course.

After a quick review of some of the important telecommunications concepts, we will study the transport technologies such as the T-Carrier and optical carrier systems, Ethernet, ATM, and Frame Relay. We will then look at the types of services that may be offered, their characteristics, and the issues unique to each. We will study the models that are used to understand and explain voice traffic, including Erlang A, B, and C, and learn how to apply them properly. We will then study the challenges posed by data traffic, including an in-depth look at VoIP traffic engineering. Upon completion of this course, you will have a good understanding of how to characterize, measure, predict, and optimize telecommunications traffic, both voice and data.
 
Audience:
 
Those who work with telecommunications networks, voice or data, and wish to understand the principles of voice/data traffic engineering.
 
Prerequisites:
 
At least two years experience in the design and optimization of a telecommunications network using any major transport technology. An engineering degree is desired, but not required. Mathematics background, especially in probability theory, will be helpful.
 
Customize it:
 
This 2-3-day Traffic Engineering for Voice and Data Networks 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.
