Traffic Engineering for Voice and Data Networks Training
Traffic Engineering for Voice and Data Networks Training Course with Labs
This two-to-three day Traffic Engineering for Voice and Data Networks Training 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 Traffic Engineering for Voice and Data Networks Training course. 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.
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.
With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
Duration: 2-3 days
