Re: Upper boundary of Adaptation Layers

Hello Brian,

I can not agree with you that SUA enables applications to use IP
addresses. Indeed Source and Destination addresses can contain IP
addresses, but this is an implicit impact on the xxUA users rather
than an explicit impact. Currently section "1.6.1.  Definition of the
upper boundary" does not extend SS7 primitives. If this extension is
wanted it shall be in the standard documents (RFCs).

Apropos Source and Destination addresses cannot contain hostnames.
IMHO hostnames are much more usefull than IP addresses.

If it is wanted that xxUA become a true standard the content of the
upper boundary shall be defined down to the last bit.

what do you mean by

?

See below for one more question.

Thank you in advance

[Ilie] Do you mean SGP to ASP interface (assuming ASP does not have
relay capability)?
