Nokia Quality of Service

Course number: 3FL30639AAAAZZZZA
Course duration: 4 days

Course overview

The Nokia Quality of Service course presents the most relevant quality of service (QoS) concepts and provides students with the key knowledge required to deploy a QoS-enabled network. The course introduces the key QoS performance metrics and explains the main functions needed to ensure that different traffic flows receive the required treatment. The QoS functions of traffic classification, policing, shaping, scheduling, and marking are explained in detail and are reinforced through hands-on lab exercises, which help students practice how to implement QoS in a Nokia Service Router network. All use cases and lab exercises are based on the model-driven command-line interface (MD-CLI).

Course objectives

After completing the course, students should be able to:

Business drivers for QoS
Parallelization of traffic stream processing as the foundation of QoS
Classification, policing, shaping, scheduling, and marking as the core QoS components
Criteria that can be used to classify packets at service and network points
The two most common resource-allocation and rate-limiting techniques: shaping and policing
Traffic metering using token buckets
Using queues as shapers
Using token-bucket policers
Buffer pool allocation for access, network, and hybrid ports
Weighted random early discard (WRED) as a technique to avoid congestion
Queue-groups and traffic redirection
Hierarchical bandwidth allocation: class fair hierarchical policing (CFHP), hierarchical scheduling (H-QoS), and egress port scheduling
Using marking to ensure a consistent treatment of data packets across the network
Marking of customer packet headers vs. marking of encapsulated packets
