The Australian Academic and Research Network Directory Services
(AARNet DS) Project is implementing a pilot, national, electronic
directory service over AARNet. This directory (in its simplest sense)
can be seen as analogous to an internal telephone directory (and
indeed can be used as such), but it is also capable of providing
access to an on-line distributed database of the individuals,
resources and organisations which form Australia's academic and
research community. With links to similar projects in many other
countries this service will become a significant component of the
global academic and research infrastructure.

The following articles contain statistics gathered in the last
month. Information in these reports covers all directories in
operation in Australia that are reachable from AARNet not just those
operated by the members of the AARNet Directory Project.

The first article gives an indication of the amount of information
available in each of the DSAs (Directory System Agents). The first
column lists the organisations (or places) with information in the
directory. The second column lists the number of entries in each of
the DSAs and the third column lists the DSA. More than one
organisation may have information loaded in any one DSA and any
organisation may run more than one DSA. Only the DSAs holding
definative information about the DIT (Directory Information Tree) are
listed.

The second of these statistics articles gives an indication of the
general availability of the DSAs. Each of the DSAs are probed several
times a day to determine whether they are available. The first column is
the number of attempts that were made to connect to the DSA, the
second the number of failures to successfully connect, and the third
the percentage of successful connections. The "Best", "Worst" and
"Ave" columns are an indication of how long it took to connect to the
DSA. The final column indicates how the attempt was made. Most of the
DSAs are only accessible via AARNet (using the Internet Protocols) but
some are also accessible via X.25.
