Hi,
I have following queries related to SCTP, RFC
2960.
1. Why SCTP performs fragmentation of data chuncks
when underlying layer (IP) does fragmentation ?
What i understand after reading RFC is that since
SCTP creates multiple streams with an association. These streams rely
on underlying layer IP to travel across network. Underlying IP can have
different MTU size. Now what SCTP does is it calculates minimum MTP size and
breaks message into this min. size and transfers it over IP so that IP dosen't
have to perform fragmentation. RFC also mentions that if SCTP does not
perform fragmentation IP does it.
2. What is difference between comulative TSN ack.
and gap ack block ?
Thanks in advance
Regards,
Deepak Rathore
