- SUMMARY -
The goal of QoS is to provide better and
more predictable network service by providing dedicated bandwidth,
controlled jitter and latency, and improved loss characteristics.
QoS achieves these goals by providing tools for managing network
congestion, shaping network traffic, using expensive wide-area
links more efficiently, and setting traffic policies across
the network.
- QoS provides guaranteed availability
- Prioritization of mission-critical
versus noncritical applications
- Interactive and time-sensitive applications
- Voice, video, and data integration
- Key QoS building blocks
