Traffic Engineering Training Overview Course Description
Good traffic engineering is not only an essential element of a network’s initial design but also critical to its smooth, ongoing operation. However, even a simple question such as how to measure the amount of traffic? defies an easy answer! As this Traffic Engineering Training Overview course makes clear, a good part of the challenge is in posing the right questions.
Upon completion of this Traffic Engineering Training Overview course, you will be able to ask the right questions, make viable conjectures, and find practical means of confirming or refuting those conjectures. This will allow you to make proper use of the teletraffic models such as Erlang-B and Erlang-C as well as other, potentially better, models. While correct usage of such models is key to the design and ongoing optimization of any communications network, this Traffic Engineering Training Overview course will focus heavily on the issues specific to mobile communications. This will enable you to use and expand the various models to account for new networks, growing network demands as well as operational optimization, such as considering handover regions and location area boundaries

» If you are familiar with some aspects of Traffic Engineering Training, we can omit or shorten their discussion.
» We can adjust the emphasis placed on the various topics or build the Traffic Engineering Training course around the mix of technologies of interest to you (including technologies other than those included in this outline).
» If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the Traffic Engineering Training course in manner understandable to lay audiences.
After completing this Traffic Engineering Training course, attendees will be able to:
At the end of this course, the participants will be able to understand traffic engineering for both voice and data networks, use of the Erlang B, extended Erlang B, and Erlang C formulae, accounting for randomness, implications of service type to bearer path characteristics and therefore bandwidth requirements, traffic engineering for data networks, and traffic simulation theory.
