my thinking about CAR and WRED :
CAR
By CAR u can set normal and max burst then tell if the rate drop from
normal then apply precedence or drop or ATM-CLP or QoS or trasmit.
General assumption:
set min xxx
max xxx
if min<flow of packet
then
drop or clp or prec or qos or transmit
end
WRED
Use the random-detect command to enable WRED, which randomly discards
packets during congestion based on IP precedence settings
General assumption:
if RED<flow of packet
then
{(set precedence 0-7) and (threshold 1-4096)}
or
set precedence to rsvp packets
my thinking is that they both are some what same but CAR is more flexible as
it gives u the upper and lower bond of limit
to traffic.
