QoS (Quality of Service)
QoS provides differentiated service levels for different types of traffic packets and guarantees
delivery of priority services during periods of network congestion. Adapting the Differentiated
Services (DiffServ) model, traffic flows are classified and marked with DSCP (DiffServ Code point)
values, and as a result receive the corresponding forwarding treatment from DiffServ-capable
routers.
