Implementing Cisco Quality of Service

This course is aimed at pre-and post-sales technical engineers responsible for designing, implementing, or troubleshooting networks and network architects responsible for designing multiservice networks to carry voice, video, and data traffic in enterprise or service provider environments.

• Explain the need for QoS, describe the fundamentals of QoS policy, 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 requirements, classify and mark network traffic in order to implement the policy.
• Use Cisco queuing 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
• Use Cisco link efficiency mechanisms to improve the bandwidth efficiency of low-speed WAN links
• Describe the recommended best practices and methods used for end-to-end QoS deployment in the enterprise.
