DESCRIPTION

19       The transport code maintains an estimate on the maximum number of out-
20       standing RPC requests, using a smoothed version of the congestion
21       avoidance implemented in 44BSD. This is basically the Van Jacobson
22

CONGESTION ALGORITHM

24       If a retransmit occurs, the congestion window is halved; otherwise, it
25       is incremented by 1/cwnd when
26
27       - a reply is received and - a full number of requests are outstanding
28       and - the congestion window hasn´t been updated recently.
