Description

This course will provide you with complete and concise knowledge on Quality of Service (QoS): how to provide a service that meets response time and bandwidth requirements? It shows the interaction of QoS with the most used protocols in the world of computer networks.

Who is this training for ?

Engineer, architect and network project manager. Any IT decision maker, particularly technical/infrastructure managers.
