Hi Group,
I have a following doubt regarding SCTP TSN/SSN Handling.
SCTP
SCTP
(Peer Node)
(Local Node)
Association is established with Local Init TSN = 0
<---------------------------------------------------------------------------
---------------------->
DATA1
----------------------------------------------------------------------------
----------------------->
TSN(0) SSN(0) StreamId = 0
DATA2
----------------------------------------------------------------------------
----------------------->
TSN(2) SSN(1) StreamId = 0
DATA3
----------------------------------------------------------------------------
----------------------->
TSN(1) SSN(2) StreamId = 0
DATA4
----------------------------------------------------------------------------
----------------------->
TSN(2) SSN(3) StreamId = 0
DATA5
----------------------------------------------------------------------------
----------------------->
TSN(3) SSN(3) StreamId = 0
What should be the behavior when we receive DATA4 and DATA5
since the SSN is in sequence but the TSN is out-of-order?
Request you to please clarify my doubt.
Thanks and Regards,
Nagesh.
