moharana_p, I have no idea what special use there is for IPSP. Because the sender of the ASP UP forms the SCTP association, it should know the identity of the ASP to which it is sending it. It is the receiver of the ASP UP, that accepted the SCTP association, that may not be able to derived from a dynamically allocated port number on the connecting peer, the ASP Id of the sender of the ASP UP. --brian [email protected] wrote: (Mon, 02 Mar 2009 04:17:17) > > Hello, > > As per the rfc-4666. > > 3.5.2.
