This read-only value reports the ABR NRM (Number of cells between forward RM cells) parameter for this SVC, which sets how frequently the source inserts an RM cell into the forward cell stream to solicit congestion feedback from the network. A smaller NRM means more frequent feedback and tighter rate control at the cost of a small bandwidth overhead from extra RM cells; a larger NRM reduces overhead but reacts to congestion more slowly. An engineer tuning an ABR SVC for a latency-sensitive application would check that cktAbrNRM is set low enough (e.g., 32 cells) to get frequent enough feedback for fast rate adjustment.
