Re: Query regarding AS and SG/IPSP

Moloud,

You are correct. As your excerpt notes, they are conceptually the same thing. The distinction is who they talk to:

An ASP  talks to an SGP
An IPSP talks to an IPSP

Subject: [Sigtran] Query regarding AS and SG/IPSP


Hi All,
 
M3UA terms in RFC confuse me:
 
IP Server Process (IPSP) - A process instance of an IP-based
application. An IPSP is essentially the same as an ASP, except that
it uses M3UA in a point-to-point fashion. Conceptually, an IPSP does
not use the services of a Signalling Gateway node.
 
 
What is this M3UA in a point to point fashion? In fact I took both ASP and ISPS the same concept, different names. 
 
Thanks,
Moloud
