\s-1POSIX.12\s0 is developing a set of protocol independent networking
interfaces.
There are no major changes in direction in the group's
direction this meeting.
Two interfaces
are proposed in language independent form \(em
the simple network interface (\s-1SNI\s0)
and the
detailed network interface
(\s-1DNI\s0).
\s-1SNI\s0 is a proposal drawn from several
sources,
with no existing
(de-facto)
standard.
\s-1DNI\s0, however, is seen as a single language
independent specification to which there are two valid C language bindings,
one for \s-1BSD\s0-style sockets
and one for the \s-1X/O\s0pen Transport Interface
(\s-1XTI\s0).
.P
The group once again reviewed the proposed changes to
\s-1XTI\s0 option management from Gerhard Kieselman,
following input from \s-1X/O\s0pen
during the intervening three months.
.P
A significant amount of time was spent in liaison with the Transaction
Processing (\s-1POSIX.11\s0)
and
Real-Time (\s-1POSIX.4\s0) working groups
as a result of the proposal from the last
meeting to include their
requirements in the \s-1POSIX.12\s0 interface.
\s-1POSIX.4\s0 requirements are
a direct result of ballot objections to the \s-1IPC\s0 interface proposed
in their current draft.
Given the announced intention of \s-1POSIX.4\s0 to include
a ``simple'' \s-1IPC\s0
interface regardless of the \s-1POSIX.12\s0
efforts,
there is some concern within our group that there are no
advantages to the proposed \s-1POSIX.12\s0 changes.
.P
Work between the meetings continues on language independent versions of the
interfaces,
and
the test methods without which the document may
not become a standard.
.P
A review of the test method
requirements revealed a significantly larger amount of work than had
originally been anticipated.
This has resulted in a change to the test method
schedule.
The mock ballot of the \s-1POSIX.12\s0 draft is not expected now
before the second quarter of 1992,
and the first real ballot not before the fourth quarter of
1992.
