15.4 ToS Settings (Layer 3 QoS)
The marking of packets at layer 3 is done by marking the ToS byte in the IP
header of the voice packet. The UNIVERGE SV9100 supports two methods for
marking the ToS byte:
IP precedence
DSCP (Diffserv)
IP Precedence
IP Precedence uses the first 3 bits of the ToS field to give eight possible
precedence values (0~7). Under normal circumstances the higher the number the
higher the priority. However this is left to the network administrator for setup. The
administrator may assign this in exactly the opposite manner with the lower
values having a higher priority. Below are the eight common values for IP
precedence.
000 is an IP precedence value of 0, sometimes referred to as routine or best
effort.
001 is an IP precedence value of 1, sometimes referred to as priority.
010 is an IP precedence value of 2, sometimes referred to as immediate.
011 is an IP precedence value of 3, sometimes referred to as flash.
100 is an IP precedence value of 4, sometimes referred to as flash override.
101 is an IP precedence value of 5, sometimes called critical.
110 is an IP precedence value of 6, sometimes called Internetwork control.
111 is an IP precedence value of 7, sometimes called network control.
