| 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: If a retransmit occurs, the congestion window is | ||
| 23 | * halved; otherwise, it is incremented by 1/cwnd when | ||
| 24 | * | ||
| 25 | * - a reply is received and | ||
| 26 | * - a full number of requests are outstanding and | ||
| 27 | * - the congestion window hasn't been updated recently. | ||
| 28 | * | ||
| 29 | * Upper procedures may check whether a request would block waiting for | ||
| 30 | * a free RPC slot by using the RPC_CONGESTED() macro. | ||
