Tolga, Brian, I see that both of you agree that in this case at ASP place we must have MTP3 (or SCCP) logic if one wants to use this configuration scenario. I think no one can question this! However the essential problem is which protocol we are to use? In my view this is the essence of the dispute. If we are to allow that ASP (or IPSP) can contain MTP or SCCP logic then the difference between the processes disappears (e.g. ASP/IPSP/SGP all can do relay/gateway/host applications) as we saw from the discussion we had last year (see thread "[Sigtran] AS concepts and Relay in SUA and M3UA" starting from December 14th 2005). So why then different protocols (ASP-SGP and IPSP-IPSP in SE and DE flavors)? However, according to Tolga's idea SG-SG protocol does support this -> i.e. MTP3/SCCP layers communicate without AS concepts in between! What is the redundancy scheme which ASP-SGP or IPSP-IPSP communication can give you and SGP-SGP communication cannot give you if in this cases ASP/IPSP'es only contain MTP3/SCCP layers (i.e. without application logic)? OTOH, I see some problems of utilizing AS concepts in between two MTP3/SCCP layers (regardless of how you call the hosting processes).... / Stanislav Tolga Asveren <[email protected]> wrote: Brian, [..snip..] > > [TOLGA]Even for PC granularity RKs, it is SG which controls/creates the > > unique view of the signaling enitity to the network, so one has to have > > necessary MTP3 procedures to support that. > > > > BTW, I wouldn't call hosting MTP3 logic in SG as "a PC in MTP3 > stack in SG", > > it is just providing necessary procedures to have the unique view of the > > signaling enitity and generating corresponding network messages > -and it is > > the multiple clones of the same unique view on different SGs, > which are not > > synchronized, which may create issues for multiple-SG scenarios-. > > STPs do this all day long. [TOLGA]On the practical side of how things work, I agree with you that with multiple-SG acting as STP scenario where RKs are in PC granularity, the possibly different views of the hosted PC are less of a problem. In such a case hosting necessary MTP3 logic for AS maps pretty much to route management from functionality point of view. _______________________________________________ Sigtran mailing list [email protected] https://www1.ietf.org/mailman/listinfo/sigtran --------------------------------- Yahoo!
