RE: ASP Active

Tolga,
I understand ur practical perspective.

However, I am more concerned from the inter-operability perspective, between
two IPSPs with different interpretations/implementations of
when-to-send-ASPAC, I mean, one IPSP is "SCCP-User aware" while the other is
NOT. The "SCCP-User aware" IPSP might expect the peer to also be "SCCP-User
aware", which might not be the case.

I believe that we have document a common interpretation on this, rather than
leaving it open ended.

Thanx.

Shashank,

IMO, when a node initiates ASPAC is more related with internal
implementation -also the relationship of LM with other entities and how that
functionality is implemented-, from M3UA-stack point of view it just means
that the node is ready to send/receive traffic for the coreresponding
traffic range and M3UA-stack should allow sich traffic to pass in both
directions, but practically without an application ready to process the
messages this wouldn't have much meaning.

     Thanks,
     Tolga
