XTI does not address management aspects of the
interface, that is:
-
how addressing may be done in such a way that an application is truly
portable
-
no selection and/or negotiation of service and protocol characteristics.
For addressing, the same is also true for TLI. In this case, it
is envisaged that addresses will be managed
by a higher-level directory function.
For options selection and/or negotiation,
XTI attempts to define a basic mechanism by
which such information may be passed across the
transport service interface, although
again, this selection/negotiation may be done by a higher-level management
function (rather than directly by the user).
Since address structure is not currently defined, the user protocol address
is system-dependent.
