Sorry, should have said multiple TCP connections vs a single SCTP
association. It's not related to pipelining but the differences in
transport level (in HTTP terms) signaling between multiple TCP
connections and a single SCTP association.

The main problem there is selective stream cancellation by the client.

If all pending requests is to be canceled together then this is not an
big issue, just tear down the SCTP association and be done with it.  But
if you need to more selectively cancel requests (i.e. a big download you
accidently started) without breaking the other concurrent pending
requests then things get a little trickier..

In the TCP case (non-pipelined) the client just closes that TCP
connection which terminates that requests with no impact on the other
requests.

Henrik
