3.6 Comparison of IP Precedence and Diffserv Values
As stated earlier, IP Precedence and Diffserv use the same field in the IP header to mark packets. It
is possible to have the same ToS value for either method which means that the two methods can
work alongside each other.
For example, if the VoIP equipment supports IP Precedence and the router can only prioritise using
the DSCP they can be set to the same value, as per the table below:
DSCP DSCP
Decimal Binary
0 000000
1 000001
2 000010
