2-day instructor-led training

• To understand the QoS fundamentals and its need in IP based networks
• To understand different queuing, shaping and scheduling techniques
• To understand the difference between IETF´s Integrated Services and the Differentiated Services models
• To understand QoS technologies at Level 2
• To relate MPLS with IP QoS

The Internet is rapidly evolving from a pure data network to a multimedia one. Users are looking for voice and video based services, as well as the basic data ones.

On one hand these are good news for service providers but, on the other hand we all know that IP, as it was developed in the beginning, is not well prepared to support these new demands. Different kinds of traffic demand different kinds of treatments from the network. Most of the new multimedia applications are time critical and basic IP is only able to handle best effort services.

Quality of Service is described in ITU-T Recommendation E.800 as: “the collective effect of service performance, which determines the degree of satisfaction of a user of a service”. IP quality of service (IP QoS) technologies have the purpose of delivering end to end QoS, by characterizing user traffic and controlling basic parameters such as: delay, delay variation, packet loss and throughput.

This course focuses in the different proposed architectures to deliver QoS, and their related parameters and protocols.

This course is very benificial as it explains the need to implement QoS and explain the methods for implementing and managing QoS. This course explains the key IP QoS Mechanisms. This course also describes how QoS works and why it is crucial to networks that must deliver integrated voice, data, and video traffic.

No pre-requisite for this course.

Network Engineers, Network Operators, Network Managers or Network Designers who are responsible for designing, maintaining and operating IP services on public or private IP networks.
