Hello,
I'm observing the following scenario when using SCTP lib as
a server: a client is sending 30 data chunk in three
packets, than another 30 with a gap in the TSN (of 1). I'm
not sure why is this gap, the client is of another
implementation.
Overall it seems ok, but the problem is that it seems the
dataArriveNotif is not called for the gap acks. Here is a
sample scenario (a wireshark translation):
client ===> 12 DATA packets, TSN 2921-2932
client ===> 12 DATA packets, TSN 2933-2944
client ===> 6 DATA packets, TSN 2945-2950
server <=== SACK, Cumulative TSN ACK 2944
client ===> 12 DATA packets, TSN 2952-2963
server <=== SACK, Cumulative TSN ACK 2950
gap ack 2952 to 2963
client ===> 12 DATA packets, TSN 2964-2975
client ===> 6 DATA packets, TSN 2976-2981
server <=== SACK, Cumulative TSN ACK 2950
gap ack 2952 to 2975
server <=== SACK, Cumulative TSN ACK 2950
gap ack 2952 to 2981
For some reason I don't get dataArriveNotif for TSN greater
that 2950 (I get only the first 30). Can you please help me
with this issue,
thanks,
Elie.
