• IP QoS Fundamentals – This objective gives the description of a converged network, identify problems that could lead to poor quality of service and explain how the problems might be resolved. It explains the term Quality of Service (QoS) and identifys the key steps to implement QoS on a converged network.
• IP QoS Components – This objective explain the models for providing Quality of Service on a network and function of the DiffServ model. It describes the purpose of the DSCP field in the IP header and different per hop behaviors used in DSCP.
• Modular QoS CLI and Auto-QoS – This objective explain how to implement a QoS policy using MQC and how AutoQoS is used to implement QoS policy.
• Congestion Management Methods – This objective explain the different queuing algorithms and the components of hardware and software queuing systems on Cisco routers. It describes the use of WFQ to implement QoS, Class-Based WFQ (CBWFQ, and ow Latency Queuing (LLQ).
• Classification and Marking – This objective explain the use of link layer and network layer markings. Use of MQC CLI commands to classify packets and use of class-based marking to assign packets to a specific service class in a given a network and a description of QoS issues.
