Quality of Service (QoS) has the capability that allows a protocol to distinguish between different classes of messages and assign priority levels. A technology that provides QoS allows an administrator to assign a priority level to time-sensitive traffic. The protocol then ensures this type of traffic has a specific or minimum rate of delivery. QoS allows a service provider to guarantee a level of service to its customers. QoS began with ATM and then was integrated into other technologies and protocols responsible for moving data from one place to another.
