Cisco QoS Fundamentals: Implementing Quality of Service

Network congestion can cripple business-critical applications, leading to dropped voice calls, lagging video, and poor user experiences. Understanding how to manage traffic flow is essential for maintaining a reliable and efficient network infrastructure. This text-only course guides you through the core principles of Cisco Quality of Service (QoS), helping you transition from basic network administration to advanced traffic optimization.\n\nWhat you'll learn:\n- Understand foundational QoS concepts, terminology, and standard deployment models\n- Classify and mark network traffic to prioritize critical application data\n- Configure queuing and congestion management tools on Cisco routing platforms\n- Apply traffic shaping and policing to prevent bandwidth exhaustion\n- Explore modern QoS strategies, including traffic profiling in software-defined networks (SD-WAN)\n\nYou will start with essential terminology and theoretical frameworks before moving on to practical, step-by-step written configuration scenarios. This course is designed for network associates and beginners looking to build a strong foundation in traffic management, with no prior QoS experience required.
