[Ashish]  No . It is not. I think this is just a recommendation.

2. If one receives 50 SCTP data packet within (say) 50ms then should we

[Ashish] Again No.

3.Think, if u generate only one SACK for those 50 data packets comming

[Ashish]  This has more to do with how soon will the peer get congested if

buffer and can hold more un-acknowledged messages, then SACKing every 50
data chunks should be fine.
