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.

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. Vint Cerf Principal Scientist DARPA/IPTO ---------- 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 Menlo Park, CA 94025 (415) 323-9481 Close by (less than a mile) Menlo Motor Lodge, ($25-30 range) 1315 El Camino Real Menlo Park, CA 94025 (415) 326-7530 Holiday Inn, ($50 range) 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. Hotels near BBN Harvard Motor Inn ll0 Mt.
