Voice and video over IP are applications that require an appropriate quality of service (QoS) from the network. Controlled runtimes, low jitter and low losses must be complemented by guaranteed bandwidth. This is the only way to ensure good quality for the end user. The methods required for this are discussed in detail in this course. You will learn in detail which functional elements are required in the network for good QoS and how they can be implemented using current technologies. Practical exercises and demonstrations on the test network ensure lasting learning success. This means you are ideally equipped to ensure optimum QoS in your own projects.

Classroom training
- Do you prefer the classic training method? A course in one of our Training Centers, with a competent trainer and the direct exchange between all course participants? Then you should book one of our classroom training dates!
-
Hybrid training
- Hybrid training means that online participants can additionally attend a classroom course. The dynamics of a real seminar are maintained, and the online participants are able to benefit from that. Online participants of a hybrid course use a collaboration platform, such as WebEx Training Center or Saba Meeting. To do this, a PC with browser and Internet access is required, as well as a headset and ideally a Web cam. In the seminar room, we use specially developed and customized audio- and video-technologies. This makes sure that the communication between all persons involved works in a convenient and fault-free way.
