hi,

I have some queries reg the implementation of sctp avilabe on sctp.de page.
I appreciate if someone cud clarify my queries:

1. Is there any upper limit on the amount of user data that can be queued up
at the tx side?
If n/w is congested and transmitter is not able to send any more data, How
long should it keep collecting data & when should it inform the ULP?

2 Is there any upper limit on the highest TSN that can be received at the
receiver or is it that any TSN would be received & stored in the buffer??
similar to upper window in sliding window protocol.



3. If "don't bundle flag" is NOT set for particular ULP DATA request, then
how long should a DATA packet wait in the bundling module to enable
bundling for this chunk.

4 Looks like MAX size if INIT or INITACK is limited to max-sctp_pdu(less
than 1500 in this case), will there be any case (as mentioned in the RFC)
where INIT/INITACK can be larger than 1500 due to variable -length nature of
cookie

5. shudn't the size of buffer that accepts datagram from raw socket be much
higher than path_mtu( since if the othe rend is not doing any fragmentation,
the receiving side can receive messages greater than path mtu size).


Thanks in advance,
Mohd. Ashraf
