This course explores the fundamental Quality of Service (QoS) mechanisms used in today's Enterprise Networks, why they are needed, and when to apply one method vs. another. Topics include classification and marking, congestion management vs. congestion avoidance, traffic shaping vs. traffic policing, and how these methods are implemented within Cisco's Hierarchical Queuing Framework (HQF). By working through hands-on QoS examples, you will gain the practical knowledge needed to optimize network performance and support modern application requirements.
