Hi Brian,

I understand your point, that "SHOULD" is only a recommendation, and hence an implementation using 2 streams would still be compliant to specs.

reg an implementation refusing to establish an SCTP association, do you mean that UA should send SCTP disconnect, if it finds out that number of streams in the established association is unsufficient?

What i understand from this is, that an implementation can only try using the recommended stream philosophy, however, if the peer node does not follow it, implementation will have 2 options:

1. Bring down the SCTP association

2. Else, it will have to start reusing the same stream for carrying data for more than one C channel.

thanks & rgds

Saurabh

Saurabh,

SHOULD not MUST.  2 streams are sufficient.  It is not an error to
place C-channels on the same stream.  If an implementation is worried
it should refuse to establish an SCTP association that does not have
sufficient streams to meet its operational objectives.
