9.1. Network Transmission Quality.
9.1.2 Prioritizing Traffic
9.1.3 Bandwidth, Congestion, Delay, and Jitter
9.1.4 Packet Loss
9.1.1 The Purpose of QoS
9.3. Queuing Algorithms.
9.3.3 First In First Out
9.3.4 Weighted Fair Queuing (WFQ)
9.3.2 Queuing Overview
9.3.5 Class-Based Weighted Fair Queuing (CBWFQ)
9.3.6 Low Latency Queuing (LLQ)
9.2. Traffic Characteristics.
9.2.3 Voice
9.2.4 Video
9.2.2 Network Traffic Trends
video traffic has become the increasingly important to business communications and operations. Consider that organizations now commonly use video conferencing to meet with users and clients, high definition video surveillance to remotely monitor facilities and equipment, and video streaming for a variety of purposes including training.

9.5.6 Marking at Layer 3
9.5.11 Congestion Avoidance
9.5.5 Marking at Layer 2
9.5.12 Shaping and Policing
9.5.4 Classification and Marking
9.5.13 QoS Policy Guidelines
Your QoS policy must consider the full path from source to destination. If one device in the path is using a different policy than desired, then the entire QoS policy is impacted. For example, the stutter in video playback could be the result of one switch in the path that does not have the CoS value set appropriately.
