If a TSN in acked using gap acks, then there is no need for SYSTEM_2
to retransmit it. But if it received by SYSTEM_2 again it will be
listed as a dup tsn.

Best regards

Hi!

            I have doubt in handling the duplicate TSN in SACK.

If a SYSTEM_1 retransmit the DATA chunk which was ACKed by the SYSTEM_2 through the GAP ack block, whether the SYSTEM_2 will treat it as a duplicate DATA chunk and will send the SACK with duplicate TSN or not?

 

 

Thanx in advance,

S.Gobinath.
