official policy, procedures and other information of concern to
management personnel at DDN facilities. Back issues may be read
through the TACNEWS server ("@n" command at the TAC) or may be
obtained by FTP (or Kermit) from the SRI-NIC host [26.0.0.73 or

ANNOUNCEMENT OF PSN UPGRADE
To all ARPANET users, Node Site Coordinators, and Host Administrators:
New versions of software are being released to the ARPANET backbone
network over the next six weeks. This will cause minimal disruption
to the user community, but will require reloading of all Packet
Switching Nodes (PSN) on the ARPANET. The software is referred to as
PSN 7.0 and contains the implementation of the new End to End
protocols. A mailbox has been set up at BBNCC for questions and
comments regarding this software upgrade. The E-mail address is
arpaupgrade@bbn.com. The standard procedure to call the BBNCC Hotline
for problems will still be in effect. The Toll free number is
1-800-492-4992.
The implementation of this software will happen in 2 phases. The 1st
phase of the PSN 7.0 implementation will require site coordination and
cooperation. All sites will have to place the new cassettes with boot
programs into their PSN's during their scheduled reboot. Sites will
be notified by the ARPANET Monitoring Center, Cambridge, MA for details and
specific times for their scheduled upgrade. New cassette tapes will
be sent to the individual node site coordinators. This phase of the
transition moves the network from the current version (PSN 6.0) to PSN
7.0 with the new End to End protocol's not configured. Individual
site upgrades will take approximately 15 minutes.
Phase II of the implementation will be the cutover to the New End to
End protocols. The initial upgrade to PSN 7.0 and subsequent cutovers
will happen in the order specified in the schedule below. Please be
aware that during the cutover period to new End to End, that said node
group will be logically segmented for a 2-3 hour test period from the
test of the ARPANET.
Any questions or comments can also be directed to Mark Whitney at
BBNCC (617) 497-2874 or Annette Bauman at DCA (703) 265-5459.
Schedule: Event:

10-24-87 The rest of the node groups cutover to new End to End,
operation verified and returned to old End to End.
10/24/87-10/31-87 Resolve any outstanding issues with above cutover.
10/31/87 Entire ARPANET cutover to use new End to End protocols,
operation verified, and return to the old End to End
mode of operation.
10/31/87-11/07/87 Resolve any outstanding issues with above cutover.
11/07/87 Entire ARPANET cutover to new End to End protocols
and left running.
