If you're getting FECN/BECN traffic then its experiencing congestion.
Congestion on the FR network prior to CIR being met is indeed a good sign of
oversubscription. If its only occasional then it may simply have been a
spike on the switch. However, if you're getting it fairly regularly, then
you need to talk to your provider. There's NO reason to set FECN/BECN when
there isn't congestion.
Ask them how they determine subscription load. Some providers (such as
Sprint last I heard) use the CIR to determine load on a switch, not the
actual traffic. If they have alot of customers with 0 CIR then the switch
can easily get oversubscribed to the point that the provider can no longer
meet the CIR of their customers.
