Quality of Service (QoS)

2 Days / 4 Live Online Sessions (0900-1230) / Technical Level: Level 3

Course Code: IP1309

Course Summary

Telecommunication networks have evolved to offer a rich mix of multimedia and voice services. Many such services depend on the Internet Protocol (IP) for their operation and networks need to be equipped and engineered to cope with changed and changing requirements. The Quality of Service (QoS) offered to users is a vital aspect of IP network engineering and is pertinent to all IP network types. This detailed Wray Castle course provides network engineers with an in-depth study that covers all the principal aspects of IP QoS in part through theory but also by means of at least 9 practical exercises.

The practical exercises will take the delegates through queue management techniques associated with switches and then routers. These exercises will include looking at QoS markings and then look at priority queueing, custom queueing, fair and weighted queueing as well as class-based routing. Exercises also cover RSVP and traffic shaping.

In order to aid the exercises a set of pods will be used where each pod consists of 3 routers and 2 switches all the ancillary cables and a laptop will be provided although it is recommended that delegates bring their own laptop to aid with testing and so that they can take example traces away with them for further study after the course.

Who would benefit

This course has been designed for those needing an understanding of the QoS engineering approaches available in IP networks. It will benefit engineers involved in network planning, commissioning, network optimization, strategy determination, deployment, equipment design or manufacturing of network equipment. Some will find that this course will satisfy their complete requirements, while for others it will provide one element in a wider study based on primary material and other related Wray Castle courses.

This course is also very useful for engineers and scientists working in areas related to IP network operation. This includes those working within service delivery, service developers, billing, Government security or forensic work, technical support staff and those in technical management roles.


A thorough foundation in the practices of IP routing would be highly beneficial before attending this course.
