This read-only value reports the ABR rate decrease factor (RDF) for this SVC, which controls how sharply the source cuts its cell rate in response to negative RM-cell feedback signaling congestion. A larger RDF causes a more drastic rate cutback per congestion signal, which clears congestion faster but sacrifices more throughput; a smaller RDF backs off more gently. An engineer seeing an ABR SVC's throughput collapse dramatically at the first sign of congestion, rather than backing off gradually, might check cktAbrRDF for an aggressively high decrease factor.
