All of these algorithms have rules to update 'cwnd' - the current congestion window, which starts out at a value controlled by consensus parameter -'cc_icw'. The algorithms also keep track of 'inflight', which is a count of -the number of cells currently not yet acked by a SENDME. The algorithm MUST +'cc_cwnd_init'. The algorithms also keep track of 'inflight', which is a count +of the number of cells currently not yet acked by a SENDME. The algorithm MUST ensure that cells cease being sent if 'cwnd - inflight <= 0'. Note that this value CAN become negative in the case where the cwnd is reduced while packets are inflight. @@ -922,7 +922,7 @@ These are sorted in order of importance to tune, most important first.
