Setting Up Statistical Multiplexing Quality of Service,
• When you select Differentiated Service as the QoS mode, you need to set the
Differentiated Service "Code Point" (DSCP) for each Stream ID. The Code
Point is 6-bit field which indicates the type of service the packet carries when
the encoder is connected to a router (i.e., to set the priority).
• When you select the ToS/CoS (Precedence), you can select from one of five
different TOS settings: Normal, Min. Cost, Max. Reliability, Max.
Throughput, and Min. Delay. The default setting for each field is Normal.
• Set the CoS (Precedence) mode settings. Some networks offer service
precedence, which treats high precedence traffic with a higher priority than
other traffic (by accepting only traffic above a certain precedence at the time
of high load). Choose from Routine, Priority, Immediate, Flash, Flash
Override, Critic ECP, Internetwork Control or Network Control. The default
is Routine.
• When you select Custom as the QoS Mode, set the 8-bit field that contains the
QoS bits. This value is a multiple of the value set for the Differentiated Service
Code point.
