JunOS arbejder med Forwarding Classes(FC) og Packet Low Priority(PLP).
Alle pakker har internt i kassen et mærkat hvor der står hvilken FC og PLP de hører til.
BA Klassificering
For at stole på den markere en pakke kommer ind med bruger man BA klassificering til at sætte FC og PLP mærkatet på pakken. Inden i kassen håndteres pakkerne nu efter markeringen.
Eksempel

[edit]Multifield Classifier
Med en MC stoler vi ikke på trafikken men bruger et firewall filter til at matche trafik og smide det i en FC og PLP.
[edit]
root@SRX07# <input>show firewall filter VLAN10-COS</input>
term PORT-80 {
from {
protocol tcp;
destination-port 80;
}
then {
count EF;
<notice>loss-priority low;
forwarding-class assured-forwarding;</notice>
accept;
}
}
term ALLOW-OTHER {
then accept;
}
root@SRX07# show interfaces vlan.10 family inet filter
input VLAN10-COS;Remarking
Inden pakken sende ud af kassen bør den markere ud fra sin FC og PLP så de næste enheder ikke skal lave en Multifield Classifier, men bare skal læse DSCP feltet.
