Introduction

In high-performance networks, ensuring that traffic is efficiently prioritized and managed is critical to achieving optimal performance. Quality of Service (QoS) plays a crucial role in meeting the performance demands of time-sensitive applications, such as VoIP, video conferencing, and real-time data services. This course focuses on advanced QoS techniques, providing network engineers with the knowledge and tools to optimize performance in complex, high-performance environments. By implementing these advanced QoS strategies, engineers can manage network congestion, guarantee bandwidth, reduce latency, and enhance the overall user experience for mission-critical applications.
