Implementing Cisco Quality of Service (QOS)

After completing this course the student should be able to:

• Explain the need for QoS, describe the fundamentals of QoS policy, and identify and describe the different models that are used for ensuring QoS in a network
• Explain the use of MQC and AutoQoS to implement QoS on the network and describe some of the mechanisms used to monitor QoS implementations
• Given a converged network and a policy defining QoS on the network and describe some of the mechanisms used to monitor QoS implementations
• Use Cisco QoS queing mechanisms to manage network congestion
• Use Cisco QoS congestion avoidance mechanisms to reduce the effects of congestion on the network
• Use Cisco QoS traffic policing and traffic shaping mechanisms to effectively limit the rate of network traffic
• Given a low speed WAN link, use Cisco link efficiency mechanisms to improve the bandwidth efficiency of the link
• Describe the recommended best practices and methods used for end-to-end QoS deployment in the enterprise

The primary target audiences for the course are:

• Pre- and post-sales technical engineers responsible for designing, implementing, or troubleshooting networks
• Network architects responsible for designing multiservice networks to carry voice, video, and data traffic in enterprise or service provider environments
• Advanced Unified Communications Specialization
• Master UC Specialization
• Master Telepresence ATP

Secondary target audiences are:

• CCIE R&S Candidates
