IP QoS Building Blocks

This course is included in our On-demand training solution.


To identify the features of different QoS implementation models, how to apply QoS mechanisms, and how packets traverse QoS-enabled networks

Target Audience

IT professionals with a thorough knowledge of networking concepts and Cisco technology basics who wish to extend their knowledge in the specific area of Quality of Service


Completion of Interconnecting Cisco Networking Devices (ICND) or Cisco Certified Networking Associate (CCNA) courses is preferred; knowledge of configuring Border Gateway Protocol (BGP)

Expected Duration

140 min.

Course Objectives

IP QoS Building Blocks

  • differentiate between the three available QoS implementation models.
  • differentiate between the types of per-hop behaviors (PHBs) in the differentiated services code point (DSCP).
  • determine a QoS implementation model and identify some issues specific to that model, in a given scenario.
  • distinguish between how classification, marking, congestion management, and congestion avoidance are implemented in a network.
  • distinguish between how policing, shaping, and link-efficiency mechanisms are implemented in a network.
  • determine where QoS mechanisms should be applied, in a given scenario.
  • identify how a high-priority VoIP packet and how a low-priority FTP packet traverse a QoS-enabled network, in a given scenario.
