Assured
Forwarding (AF)
PHB
Assured Forwarding (AF): Has four classes and three
drop-precedence within each class (so a total of twelve
codepoints). Excess AF traffic is not delivered with as high
probability as the traffic "within profile," which means it may be
demoted but not necessarily dropped DiffServ AF
Expedited
Forwarding (EF)
PHB
Expedited Forwarding (EF): Has a single codepoint (DiffServ
value). EF minimizes delay and jitter and provides the highest
level of aggregate quality of service. Any traffic that exceeds the
traffic profile (which is defined by local policy) is discarded
