Report Transport on Protocols

                                 NOTICE

The project that is the subject of this report was approved by the
Governing Board on the National Research Council, whose members are
drawn from the councils of the National Academy of Sciences, the
National Academy of Engineering, and the Institute of Medicine.  The
members of the committee responsible for the report were chosen for
their special competences and with regard for appropriate balance.

This report has been reviewed by a group other than the authors,
according to procedures approved by a Report Review Committee consisting
of members of the National Academy of Sciences, the National Academy of
Engineering, and the Institute of Medicine.

The National Research Council was established by the National Academy of
Sciences in 1916 to associate the broad community of science and
technology with the Academy's purposes of furthering knowledge and of
advising the federal government.  The Council operates in accordance
with general policies determined by the Academy under the authority of
its congressional charter of 1863, which establishes the Academy as a
private, nonprofit, self-governing membership corporation.  The Council
has become the principal operating agency of both the National Academy
of Sciences and the National Academy of Engineering in the conduct of
their services to the government, the public, and the scientific and
engineering communities.  It is administered jointly by both Academies
and the Institute of Medicine.  The National Academy of Engineering and
the Institute of Medicine were established in 1964 and 1970,
respectively, under the charter of the National Academy of Sciences.

This is a report of work supported by Contract No. DCA-83-C-0051 between
the U.S. Defense Communications Agency and the National Academy of
Sciences, underwritten jointly by the Department of Defense and the
National Bureau of Standards.
