Presentation Transcript

  1. Quality of Service CCDA Quick Reference

  2. QoS Mechanisms

  3. Bandwidth Provision • Call Admission Control – provision applications to a certain bandwidth or resource limit so they do not negatively affect other applications.

  4. Signaling Techniques • The Resource Reservation Protocol (RSVP) allows bandwidth and other resources along the routing path to be reserved so that a certain level of quality is provided for delay-sensitive traffic.

  5. Classification and Marking • Classification is the process of partitioning traffic into multiple priority levels or classes of service. • Marking is the process of changing the priority of class of service setting within a frame or packet to indicate its classification

  6. Congestion Avoidance • Congestion-Avoidance techniques monitor network traffic loads so that congestion can be anticipated and avoided before it becomes problematic.

  7. Traffic Policing and Shaping

  8. Congestion Management Scheduling – decides from which queue traffic is to be sent next.

  9. Link Efficiency • Link Efficiency reduces unacceptable delays on low-speed links with Link-Fragmentation and Interleaving and Compression schemes

  10. Layered QoS Model Citation for this picture is provided in the next slide
