Implementing Cisco Quality of Service [QOS]

OVERVIEW

The Implementing Cisco Quality of Service (QOS) course provides learners with an in-depth knowledge of QoS requirements, conceptual models such as best effort, IntServ, and DiffServ, and the implementation of QoS on Cisco platforms. The curriculum covers the theory of QoS, design issues, and configuration of various QoS mechanisms to facilitate the creation of effective administrative policies providing QoS.

Case studies and lab exercises included in the course help learners to apply the concepts from the individual modules to real-life scenarios.Learners are provided with design and usage rules for advanced QoS features, giving them the opportunity to design and implement efficient, optimal, and trouble-free multiservice networks. This version of the course also includes QoS for modern wireless networks and Software-defined networks.

This course is worth 40 Credits on the Continuing Education Program

OBJECTIVES

After you complete this course you will 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.
• Describe how link efficiency mechanisms can be used collectively to improve bandwidth efficiency and reduce delay.
• Describe the need for wireless quality of service (QoS) in WLANs due to the expansion of high-bandwidth data applications and time-sensitive multimedia applications in vertical and enterprise environments, and the need for a unified approach to support multi-vendor time-sensitive applications and accelerate the adoption rate of QoS.
• Describe the need for  quality of service (QoS) in modern Software Defined Networks (SDN) for ensuring reliable performance of crucial applications and services.
• Describe the steps and best practices for optimally deploying QoS and understand the network elements involved in an enterprise end-to-end QoS deployment, as well as the importance of QoS interaction between the enterprise and service provider networks.

AUDIENCE

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