Re: AS, RK , RC concepts in SE model

Hello Brian,

in my view this is a considerable change of AS concept. In SIGTRAN an
AS is an application server sitting behind its ASPs/IPSPs. Now you say
an AS is a bidirectional signalling relation and not an Application
Server.

The same goes for RK,  RK1 cannot be the same as RK2, because Routing
Key defines where messages go, it defines routing.

In my view the concept of Application Server cannot be dependent on
the exchange model used. How can we make the main SIGTRAN concept
dependent on the communication model?

Any other opinions?

Regards

Ilie
