QoS Packet Scheduler

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

The Quality of Service Packet Scheduler is a Windows platform component that is enabled by default on Windows Vista® and Windows XP computers. It is, however, not enabled by default on Windows 2003 computers. This scheduler is designed to control the IP traffic for various network services, including Real Time Communications traffic. This component must be installed and enabled if the QoS markings described earlier for audio and video traffic are to be implemented by the IP stack.

Below are described the procedures to follow to install the QoS Packet Scheduler in the case it is not present. As mentioned earlier in this document, the QoS Packet Scheduler will mark the outgoing IP packets according to the directives captured in the QOS and FLOWSPEC structures.
