- \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.
