Hideki,

you are wrong. SCTP_MAXIMUM_DATA_LENGTH is a constant in
sctp.h which should not be changed by the user. It is the
maximum data chunk length which fits in an ethernet frame with
a common header and a small SACK chunk.

You should never anything in scyp.h

Segmentation and reassembly work out of the box. See programs/echo-tool.c
for an example. Just use large buffers in the sctp_send and provide
large buffers in the sctp_receive calls.

Best regards
Michael

Dear all,

Question to user-data fragmentation and reassmenble:

#define SCTP_MAXIMUM_DATA_LENGTH 1400
change to
#define SCTP_MAXIMUM_DATA_LENGTH 8000

In this case, as for sctplib can it send and receive the user-data
of 8000 octets correctly?


regards,
Hideki (Japan)
