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
