Quality of Service (QoS)

A system not a protocol

The goal of QoS is a guaranteed delivery system for network traffic, such as Internet Protocol (IP) packets. The set of mechanisms QoS uses to achieve this goal includes services and protocols. The Windows 2000 implementation of QoS includes:

• A subnet bandwidth management (SBM) service for controlling bandwidth on a subnet. 

• Integrated Resource Reservation Protocol (RSVP), enabling the sender and receiver of a communication to establish a reserved, QoS highway for traffic. 

• Traffic control services for prioritizing and scheduling traffic.
