ARPANET LIAISON INVITED TO MEETINGS TO DISCUSS TCP/IP TRANSITION
The ARPANET Liaison are cordially invited to attend one of two
meetings scheduled for March 1982 - one on the East Coast and one on
the West Coast - to discuss the planned transition from the NCP
protocols to the TCP/IP protocols during 1982. This transition is
part of a larger DoD standardization activity which was set into
motion in April 1980 by Gerald Dinneen, then the Assistant Secretary
of Defense for Command, Control, Communications and Intelligence. In
his April 3, 1980 directive, Dr. Dinneen identified the Transmission
Control Protocol and Internet Protocol as ratified DoD standards and
placed DCA in charge of managing their further development,
specification, and application in multinetwork environments.
Since that time, DCA, DARPA, and other DoD representatives have
worked to refine the specifications and to test a variety of
implementations on a wide range of computers, operating systems, and
networks. Just as it did a decade ago, tha ARPANET community is
leading the way into a new networking territory of great importance
to the future of US military command and control systems. This
transition effort on the ARPANET has the sanction and encouragement
of the DCA ARPANET Management Branch and the DoD protocol
standardization organization as well as the support of the Office of
the Undersecretary of Defense for Command, Control, Communications
and Intelligence.

THE C/30 UPGRADE ON THE ARPANET
The ARPANET IMPs and TIPs are based on Honeywell 516 and 316
computers which are reaching the limit of their useful lifetimes.
Bolt Beranek and Newman has developed a replacement processor called
a C/30 which has already been installed at a number of sites on the
ARPANET. The ARPANET sponsors are generally planning to order
replacements through DCA for all the Honeywell IMPs on the network.
ARPA has ordered a number of C/30 IMPs to replace existing ones. In
addition, the ARPANET TIPs are being upgraded to include both NCP and
TCP/IP software along with TELNET protocol as part of the general
transition into the internet environment.
The upgraded TIPs are being re-named TACs (Terminal Access
Controller) and perform only host functions. A Honeywell TIP becomes
a TAC when it is plugged into an IMP host port and its software is
re-loaded to include both NCP and TCP/IP protocols. BBN has also
developed a C/30 TAC and there are a few of these on the net as well.
Over the course of calendar 1982 and probably into early 1983, the
Honeywell IMPs will be replaced with C/30 IMPs. Also, all the
Pluribus TIPs and IMPs will be replaced with C/30 IMPs and C/30 TACs.
As an ARPANET sponsor, DARPA/IPTO has ordered or will order C/30 IMPs
during 1982 to replace all the Honeywell or Pluribus IMPs for which
it is responsible. Honeywell TIPs will be converted to TACs. In
1983, DARPA will begin replacing the Honeywell TACs with C/30 TACs so
that, by the end of calendar 1983, the DARPA/IPTO sites will have
been fully converted to C/30 equipment. The other ARPANET sponsors
have similar plans, although I cannot vouch for the precise timing of
their actions.
I have requested that BBN send to each site liaison a configuration
plan for the C/30 IMP replacements for which DARPA/IPTO is
responsible. Ms. Judy Gordon (JGordon@BBN) has or will shortly be
sending to a subset of the liaisons, the configurations we are
ordering for those sites. I would appreciate liaison review of the
configurations and response to Judy Gordon if there are questions or
problems. Particular attention should be paid to planning for
connector and cable arrangements as these have often been a problem
area in the past when a C/30 replacement IMP arrives at a site.
If you are a liaison who has not or does not within a couple of weeks
received such a configuration plan, I urge you to get into contact
with your ARPANET sponsor to determine the plans for your C/30 IMP
replacement.
Details about the C/30 product line can be obtained from Judy Gordon.

TCP/IP DIGEST
Mike Muuss at the Ballistics Research Lab., Md. has started a special
interest group on TCP/IP protocols which you may want to join. He
would be happy to add you to the distribution list for his TCP/IP
Digest, and would like to receive current information on TCP
implementations and questions/answers on status and issues. The NIC
would also like to be cc:ed (NIC@SRI-NIC) on the latter.
Contact Mike@BRL.

TRAVEL INSTRUCTIONS FOR LIAISON MEETINGS
GETTING TO SRI INTERNATIONAL
Most of the Liaison can either drive in or fly in for the day. The
meeting does not start until 10 AM to give people from Southern
California time to get to SRI from the airport. Hotels are listed
below for anyone who plans to stay overnight.
Menlo Park is about equidistant between San Francisco or San Jose
airports, so flights to either airport are OK. To get to SRI in
Menlo Park take Freeway 101 (also called The Bayshore) north from San
Jose, or south from San Francisco, to the Willow Road/Menlo Park
(west) exit (don't take the Willow Road/Dumbarton Bridge exit or you
will be headed in the wrong direction). Drive up Willow Road to the
3rd traffic light which will be Middlefield Road. Turn right on
Middlefield Road. At the 2nd traffic light turn left onto Ravenswood
Ave. SRI is a red brick building on the left. Turn into the main
entrance, enter the main door behind the white pillars, and check in
with the receptionist. Visitor parking is on the left facing the
building.
To reach the hotels, continue over the railroad tracks to the next
light which will be El Camino. Turn left if staying at the Mermaid
Inn or Holiday Inn and right if staying at the Menlo Motor Lodge.
If you are not renting a car, it is best to book a limosine in
advance. The limos are fairly expensive...about $18. There are some
buses, but the schedules are not good for reaching Menlo Park,
unfortunately.
Hotels in the area are:
Walking distance
The Mermaid Inn, ($25-30 range)
727 El Camino Real

625 El Camino Real
Palo Alto, CA 94035
(415) 328-2800
TO GET TO BOLT, BERANEK, AND NEWMAN, INC.
From Logan Airport, take Sumner Tunnel to Southeast Expressway -
North (2nd exit up the ramp after tunnel). Take Storrow Drive
exit, and follow Storrow Drive to end, and then follow Rt. 2-3
(Fresh Pond Parkway) to Howard Johnson's. Bear left at traffic
rotary, so ARCO service station is on your right. Second right is
Fawcett Street. Parking is available in the small lot in front of
the building.
