Subject:    [Tsvwg] question about SCTP

Hi,

1.
In the definition of RFC 2960, two SCTP endpoints MUST NOT  have more than
one SCTP association between them at any given  time.

A host can configure into more than one SCTP assocations;  therefore,
two Host can have more than one SCTP associations between  them.
Is this statement correct?

[RE]-> Theoretically, yes this is correct, but one could
use the multi-homing feature to use the multiple IP
addresses and  multi-streaming feature to differentiate
different logical streams.

2.
If SG accept 10000 call setup siganl from SS7, and the  SG establish a SCTP
association for these calls to a AS.
Some of the calls may be completed early, so the streams in  the
assocaition for these calls are idle.
Can this idle streams be used for new SS7 setup calls? Or, new  SS7 call
setup must establish their new SCTP association.
[RE]-> If you are taking of M3UA above SCTP, then one would
not have one stream per call. Each SLS could be one different
stream and thus stream would not dynamically increase or decrease.
The streams would carry ISUP messages for all the calls
that the ISUP decides to put on a particular SLS.

Thanks
