Course duration: 4 days
Price: $3,125 US

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
