Quality of Service

Introduction

Focus Keyphrase: Quality of Service Training — This Quality of Service Training course is designed to help learners master QoS concepts, traffic management techniques, and network performance optimization, laying a solid foundation for real-world enterprise networking.

Course Overview

Quality of Service (QoS) is a critical networking capability that ensures reliable, predictable, and optimized data delivery across modern networks. This course provides a deep, structured understanding of QoS mechanisms, classification, marking, queuing, congestion management, and traffic shaping. Whether you work with Cisco devices or mixed-vendor architectures, this course equips you with the skills required to manage bandwidth, reduce latency, and ensure seamless application performance.

You will explore the different QoS models such as Best Effort, Integrated Services (IntServ), and Differentiated Services (DiffServ). Additionally, you will learn how QoS policies are implemented in enterprise networks, service provider environments, and data centers to support voice, video, and mission-critical applications.

What You Will Learn

• Fundamentals of QoS and why it matters in modern networking
• Classification and marking using DSCP, CoS, IP Precedence
• Queuing mechanisms: FIFO, WFQ, CBWFQ, LLQ
• Congestion avoidance: RED, WRED
• Traffic shaping and policing concepts
• QoS strategies for voice, video, and real-time applications
