Read what I wrote ...
The route through the network has to depend on the sls.
So the =91stream=92 on an sctp link has to depend on the sls.
Unless you know by some other means that the ordering of the traffic doesn=
=92t matter.
Which can be arranged to be true for locally generated TCAP traffic that th=
at doesn=92t
request =91sequential delivery=92 from SCCP, and has not been fragmented.

Thanks David for the reply.
But I am still unclear about following points ::
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D
1)
Is there a one-to-one mapping between a SLS and a SCTP-link? Or a one-to-ma=
ny mapping between a SLS and SCTP-links?
2)
Assuming there is a one-to-one mapping, still there might be chances of seq=
uencing-failures, IF different "streams" are selected within the same SCTP-=
link?
Thanks and Regards,
Ajay

Pardon me.. I meant "SLS".

Will be grateful for clarifications.
