Quality of Service

Quality of Service (QoS) facilitates the deployment of media-rich applications, such as video conferencing and Internet Protocol (IP) telephony, without adversely affecting network throughput. Microsoft® Windows® 2000 QoS also improves the performance of mission-critical software such as Enterprise Resource Planning (ERP) applications. Windows 2000 supports the QoS Admission Control Service, a policy mechanism that offers the ability to centrally designate how, when, and by whom network resources are used on a per-subnet basis. QoS is an emerging technology, with standards that are being developed and revised based on customer feedback and industry-wide cooperation.

This chapter focuses on the Windows 2000 deployment of QoS and the QoS Admission Control Service. These technologies are based on standards created by the Internet Engineering Task Force (IETF).
