Not all network traffic is equal. A video call dropping frames ruins communication. A file download taking an extra second does not matter. Quality of Service (QoS) lets you prioritize traffic that needs it most.
I'll cover these QoS concepts:
- Why real-time traffic needs special handling
- Classification and marking with DSCP and CoS
- Queuing mechanisms that prioritize traffic
- Congestion avoidance techniques
- Shaping versus policing
- IntServ and DiffServ models
You'll learn to design networks that deliver consistent performance.
