4.10 Adaptive retransmission

Most client implementations use either an exponential back-off strategy to some maximum retransmission value, or a more adaptive strategy that attempts congestion avoidance. Congestion avoidance schemes in NFS request retransmission are modelled on the work presented in [Jacobson]. [Nowicki] and [Macklem] describe congestion avoidance schemes to be applied to the NFS protocol over UDP.
