DESGN 3.0: Supporting QoS and Wireless in a Network Design

This path is intended for anyone who is interested in developing the skills needed to successfully design networks that will support voice, video, and data communications.


Expected Duration
112 minutes

In a perfect world there would be no competition between traffic on a network and all traffic would be created equal. However, that is not the case. In order to support different applications and traffic types on the same network, you need to design QoS to ensure that sensitive traffic has priority. In addition, with the increasing number of mobile devices in networks you need to design a network that will be able to support wireless LANs. This course introduces you to QoS and covers design best practices for QoS mechanisms such as Classification, Marking, Policing, Shaping, and Re-marking. The course also covers Wireless LANs and the different design options that are available to meet business needs.
