There are some situations when running two paralel PVCs is necessary in
FR clouds experiencing congestions.
Sometimes FR network are implemented in such way that
network device at cloud edge allow customers to transmit frames
exceeding CIR without setting DE bit at entry point.
When customer want to be sure that priority data frames within CIR bandwidth
would not be dropped, he must mark other nonpriority frames with DE bits.
Assuming that other customers transmit all frames within cir and above
without setting de bits, theirs frames are preferred at congestion points.
The workaround for this inequal treatment is to run two pvc's - one subscribed
with cir and one without cir, putting all nonpriority data into second pvc
not marking it with de bits.
