Quality of Service (QoS)
A Quality of Service (QoS) setup is used to prioritise different types of network data. So, for example, RAVENNA
timing information and audio streams
MUST
take priority over all other types of network traffic.In Lawo's
RAVENNA devices, the following DSCP classes are implemented. By prioritising these classes within the switch
configuration, in the order shown below, you can ensure that PTP clock, and then RAVENNA media streams
always take priority:
·
DSCP 56 (C7) = PTP clock signals.
·
DSCP 46 (EF) = RAVENNA media streams.
·
DSCP 0 (BE) = all other network traffic.
On the CISCO switch interface, the important parameters are shown below.
