Slow-Start




1The initial cwnd before DATA transmission MUST be set to min(4*MTU, max (2*MTU, 4380bytes))PASSXXXLink0
2The initial cwnd after a retransmission timeout MUST be no more than 1*MTUPASSXXXLink0
3The cwnd MUST be increased the size of outstanding DATA chunk(s) acknowledged if it is less than PMTUPASSXXXLink0
4The cwnd MUST be increased 1 PMTU if size of outstanding DATA chunk(s) acknowledged is larger than PMTUPASSXXXLink0
5The initial cwnd should not chang as flight_size is less than the cwndPASSXXXLink0
6The cwnd of the transport address should be adjusted to max(cwnd/2, 4*MTU) when does not transmit dataPASSXXXLink0
7Protocol parameter Max.Burst limits the number of new data chunks that can be sentPASSXXXLink0

Congestion Avoidance




8Increase cwnd by MTU when partial_bytes_acked is equal to or greater than cwndPASSXXXLink0
9The cwnd of the transport address should be adjusted to max(cwnd/2, 4*MTU) when no transmit dataPASSXXXLink0
10The partial_bytes_acked is set to 0 when all of the data transmitted has been acknowledgedPASSXXXLink0

Congestion Control




11Verify that cwnd is update correctly after a fast retransmitPASSXXXLink0
12Verify that cwnd is update correctly when T3-rtx timer expires on an addressPASSXXXLink0

Fast Retransmit




13Restart T3-rtx timer if the endpoint is retransmitting the first outstanding DATA chunkPASSXXXLink0

Fast Recovery




14The ssthresh and cwnd SHOULD NOT change while in Fast RecoveryPASSXXXLink0
