The following is information on QoS for Nefsis traffic.

DSCP (QoS implementation):
This allows customers to prioritize network traffic IF a few conditions are met:

1. Their clients are running Windows Vista or later (there is no means available to support Windows XP or 2000)
2. The VCS is running on Windows Server 2008
3. The routers between the client and server support DSCP (this means that in order to be prioritized the traffic must not leave their network. There is no such thing as ‘prioritized to their router’ or ‘half prioritized’. It either is or it is not.)

The list of DSCP CodePoints that we offer (from lowest priority to highest):

QOSTrafficTypeBestEffort
Flow traffic has the same network priority as regular traffic not associated with QOS.

QOSTrafficTypeBackground
Flow traffic has a network priority lower than that of

QOSTrafficTypeBestEffort. This traffic type could be used for traffic of an application doing data backup.

QOSTrafficTypeExcellentEffort
Flow traffic has a network priority higher than

QOSTrafficTypeBestEffort, yet lower than QOSTrafficTypeAudioVideo. This traffic type should be used for data traffic that is more important than normal end-user scenarios, such as email.

QOSTrafficTypeAudioVideo
Flow traffic has a network priority higher than

QOSTrafficTypeExcellentEffort, yet lower than QOSTrafficTypeVoice. This traffic type should be used for A/V streaming scenarios such as MPEG2 streaming.

QOSTrafficTypeVoice
Flow traffic has a network priority higher than

QOSTrafficTypeAudioVideo, yet lower than QOSTrafficTypeControl. This traffic type should be used for realtime voice streams such as VOIP.

QOSTrafficTypeControl
Flow traffic has the highest network priority. This traffic type should only be used for the most critical of data. For example, it may be used for data carrying user inputs.
