MILNET/MINET INTEGRATION
Integration of the USEUCOM MINET communication subsystem
(including all backbone and access lines) into the DDN
unclassified segment (MILNET) was completed on 18 December 1984.
The ongoing MINET stage II (western Med.) installation will be
completed under current contract arrangements. Further expansion
of communications support to the MINET user community, including
engineering and installation of stage III (eastern Med.), will
evolve through follow-on expansion of the MILNET. This expansion
will include increased inter- and intra-theater connectivity as
part of the DDN program. (James Powell, B613, 703-285-5101, (V)
356-5101.)
DDN NODE INSTALLATION SCHEDULE
The DDN PMO has completed an initial draft Node Installation
Schedule which encompasses 120 new DDN MILNET, DISNET, and DODIIS
installations between February 1985 and April 1986. A majority
of sites have completed their nomination/presurvey and site
survey processes, and many are ready to begin equipment
installation. Detailed schedules which were coordinated in
February with Service representatives and the DDN principal
contractor, BBNCC, have been published and forwarded to the
Services and DCA Action Offices for implementation.
Two major changes to installation approach have been directed:
1. Node equipment (i.e., processor, modem and crypto
cabinets) will be installed and integrated into site
facilities in accordance with site survey
documentation independent of the availability of
interswitch trunk (IST) lines. In those cases where
IST availability does not support activation at the
time installation is complete, DCA will have the
contractor revisit the site when the ISTs are turned
on for use not only to complete integration of the
node into the network, but to execute line and
2
DDN Newsletter Special Issue 39 25 Apr 1985
equipment performance testing and acceptance.
2. DCA will fund and/or perform site engineering and
installation tasks in support of the installation plan
and schedule when the Service E&I agency cannot
support the required schedule. This approach is taken
temporarily to expedite completion of the crucial
expansion effort through April 1986 and to permit the
services to successfully complete programming actions
to support site E&I work beginning April 1986.
(Ltc Bruce Sweeney, B647, 703-285-5007, (V) 356-5007.)

DODIIS NETWORK
The Department of Defense Intelligence Agency Information System
(DIA/DODIIS) community will have a secure data network consisting
of C/30 IMPs and a C/70 Monitoring Center at approximately 40
sites around the world within the next four years. The
subnetwork, provided by the DDN PMO, will be integrated into the
DDN Integrated Secure Network (DISNET) when blacker devices
become available. Service O&M commands have been requested to
confirm site selection/nominations made by DIA for the 1985
DODIIS expansion. DODIIS also has a test facility consisting of
2 C/30s, a C/70 MC, and supporting TEMPEST terminals and printers
located in the DIAC at Bolling AFB. The initial phase of
installation, including sites and trunks, is underway. The
completion of the DODIIS AFIS site has been delayed due to a
facility rehabilitation project. Other DODIIS site installations
are being delayed due to problems with ATTIS and BOCs in
providing interswitch trunks. Current information indicates an
IOC in the May/June 1985 time period. (Mr. Charles F. Russell,
703-285-5102, (V) 356-5102.)
HOST INTERFACE QUALIFICATION ACTIVITY
The Test and Evaluation Branch, B617, recently tested the
Advanced Computer Communications (ACC) IF-11/X.25 version 3.7
interface and it was granted a fully qualified status to operate
on the DDN. Several other interfaces are currently being tested
and are close to passing the qualification test. (Mr. Chuck Ely,
B617, 703-285-5337, (V) 356-5337)
DRAFT DCA CIRCULAR FOR X.25/1822 HDH QUALIFICATION TESTING
A draft DCAC 370-P195-XX entitled "Defense Data Network
Qualification Testing-Link and Network Layers" is complete and in
the process of being edited. This circular provides the
administrative actions and test procedures necessary to insure
that candidate hosts for the Defense Data Network (DDN) will
properly interface with the network. Both access protocols--X.25
4
DDN Newsletter Special Issue 39 25 Apr 1985
and 1822 HDH--required for qualification are covered. (Mr. Chuck
Ely, B617, 703-285-5337, (V) 356-5337.)
DDN HOST INTERFACE ACQUISITION
To increase the commercial availability of DDN interfaces for
major computer systems, the DDN PMO has now awarded to various
vendors a total of seven contracts. The two most recent
contracts were awarded to Honeywell Information Systems for the
DPS 8 GCOS 8 family, and to IBM Corporation for the IBM 370 VM
family. An eighth contract is currently in progress.
Contracts awarded to-date are listed below:
Company Host Family
Control Data Corporation CDC Cyber 170 - NOS
Gould Software Division DEC VAX - VMS
Honeywell Information Systems HIS DPS 8 - GCOS 8
Honeywell Information Systems HIS Level 6 - GCOS 6 MOD 400
Network Solutions IBM 370 - MVS
IBM Corporation IBM 370 - VM
Internet Systems Sperry 1100 - OS/1100
These contracts require that the interface be installed and
tested in a government-designated test site. The U.S. Army
Information Systems Software Support Command, Falls Church,
Virginia, has been designated as the test site for the IBM 370 VM
interface. Selection of other test sites is in progress.
PERSONAL COMPUTER (PC) SUPPORT
The DDN PMO has launched several initiatives to improve personal
computer access to the MILNET, recognizing that the use of
personal computers is one of the Military Department's fastest
growing needs in computer processing.
To provide a more suitable PC interface for the short term, some
5
25 Apr 1985 DDN Newsletter Special Issue 39
minor enhancements are planned for the C/30 TAC. While the C/30
TAC is superb at providing an interface with a human at a
keyboard, it was never intended to handle the steady data stream
generated by a personal computer uploading a file, or to provide
many of the applications being requested by the growing tide of
personal computer users.
Enhancements currently being worked on include changes in flow
control handling and provision for direct communication from PC
to PC. For instance, the effective data throughput of a C/30 TAC
for a pc-to-host connection is between 300 and 1200 baud,
depending on the make of the PC and the software in use on it.
In particular, flow control handling problems are caused when a
TAC transmits an XOFF signal to the PC to stop the flow of data.
Currently, this occurs when the input buffer is within 12
characters from overflow. This is more than adequate when the
TAC is interfacing with a human being, as it was designed to do.
However, many PCs simply do not react to the XOFF quickly enough
to avoid overflowing the 12 character spaces left in the TAC's
input buffer. A corrective action under consideration to
compensate for this problem includes raising the TAC's XOFF
trigger point from 12 characters to a greater value, thus giving
the PC more time to react.
For the long term, a different approach is required. Although
some limited gains such as described above are possible with the
C/30, any other substantial changes would require major
modifications to TAC hardware or software or both. This is not
desirable for a variety of reasons. A number of options are
under study, and a decision is expected later this year regarding
the optimum approach. (Maj. Glynn Parker, 703-285-5133, (V)
356-5133.)
MILNET TAC ACCESS CONTROL
The MILNET TAC Access Control System (TACACS), Phase 1, was
extended into Europe in January 1985. Initially, the system was
implemented with a universal password for familiarization
purposes as was done with MILNET TACACS, in the CONUS and Pacific
areas, and the system became fully operational using unique
6
DDN Newsletter Special Issue 39 25 Apr 1985
individual IDs and Access Codes on 6 February 1985.
ARPANET introduced a separate login system in January 1985.
ARPANET TAC login uses conventional passwords which are validated
by login hosts whereas MILNET TACACS validation of IDs and
passwords is handled in the IMP or node. Phase 2 of MILNET
TACACS involves a plan to use login hosts, pending a period of
observation and careful evaluation of the ARPANET system. (Maj.
Glynn Parker, 703-285-5133, (V) 356-5133.)
DEADBOLT--AN ENCRYPTION/AUTHENTICATION DEVICE
A prototype device, known as DEADBOLT, is being constructed for
NSA by the MITRE Corporation. DCA is participating with NSA in
the development of this Low-cost Encryption/Authentication Device
(LEAD) for terminal-to-host communication in unclassified
applications. This prototype will be used in an operational test
to be conducted in late spring. (Maj. Glynn Parker, 703-285-5133,
(V) 356-5133.)
USER REQUIREMENTS DATABASE (URDB) STATUS
As of 31 January 1985, the User Requirements Data Base has a
total of 4561 Hosts and 16641 Terminals registered. Navy and Air
Force have started validation efforts in order to clean up their
portion of the database. On-site training was conducted at
COMNAVTELCOM in Washington, and Gunther AFB, Alabama.
Efforts have also begun in the redesign of the database in
preparation for conversion to ADABAS. This work is scheduled to
begin during the next quarter. (Ms. Sandy Vest, B616,
703-285-5456, (V) 356-5456.)
TELECOMMUNICATIONS SERVICE REQUESTS (TSRS)
The DDN PMO Telecommunications Management Section has been
7
25 Apr 1985 DDN Newsletter Special Issue 39
reorganized, according to Mr. John Claitor, Chief of the Data
Base and Configuration Management Branch. This section,
presently under control by this branch, is responsible for
processing all requirements attached to the Feeder TSR forms--the
forms to request DDN service. Headed by Mr. Ron Gutschmidt, the
section encompasses three data entry personnel, two port
allocators, four technical administrative personnel and one work
administrator. An additional three technical administrative
personnel and one port allocator are being recruited in order to
satisfy user and backbone requirements in an orderly and
effective manner.
The requirements processed within the DDN PMO have increased
considerably over the past two years. In FY 1983, a total of 521
DDN TSRs were processed, and in FY 1984, 1290 DDN TSRs were
issued. So far in FY 1985, a total of 800 DDN TSRs (Oct-Jan)
were processed, with an estimation of 3000 DDN TSRs to be
processed during the FY 1985 year. Presently, this section
processes approximately 40 DDN TSRs to the field each week,
including user requirements, backbone trunks and dial-up service
lines to the TAC.
The processing of DDN TSRs is being accomplished using a
semi-automated process by a direct connection to the DCA/DCAOC
computer. Feeder TSRs are received, transformed into a DDN
formatted TSR and turned over to the technical administrative
personnel. Information is then added by the port allocators and
technical administrative personnel, reviewed by the work
administrator, and finally transmitted by the data entry
personnel.
However, the process is still being hindered because some TCOs
have not addressed the Feeder TSRs to the correct RI (RUEJDDN)
and PLA (DDN PMO TSR-CRP TRAFFIC WASHINGTON D.C.).
DDN COST ALLOCATION MODEL
The September 1984 Defense Data Network Cost Allocation Model was
distributed on 10 January 1985. Publication of the Cost
Allocation Model came in response to requests from prospective
8
DDN Newsletter Special Issue 39 25 Apr 1985
DDN users that a method be provided by which various proposals
for utilization of the DDN may be compared and evaluated during
the ADP acquisition process. Limited distribution was made to
cognizant DoD agencies and MILDEP activities and each MILDEP,
DCS, or O&M command was provided with 150 copies for their
distribution.
Entry of this publication into the Defense Technical Information
Center (DTIC) is also planned. In the interim, requests for
copies should be addressed to the parent agency or MILDEP, DCS,
or O&M commands. (James Powell, B613, 703-285-5101, (V)
356-5101.)
DDN LOGISTIC SUPPORT
The 1 December 1984 DDN Newsletter reported that the DDN PMO had
tasked Dynamics Research Corporation to do a comparative logistic
support concept analysis for DDN. The final report of the
analysis has been delivered and is being integrated into the
Logistic Support Concept for DDN.
A Management Team (ILSMT), hosted by the Deputy Program Manager
for Logistics (DPML), was held at 7915 Westpark Drive, McLean,
Virginia on 12 and 13 March 1985. (James A. Evans, B635,
703-285-5443, (V) 356-5443.)
NETWORK ACCESS COMPONENT (NAC) UNITS FOR THE DEFENSE DATA NETWORK
A firm-fixed-price contract, DCA200-85-C-0007, was awarded on 12
February 1985 to Aydin Monitor Systems, 502 Office Center Drive,
Fort Washington, Pa 19034, in the amount of $3,890,732. This
contract is for the development of NAC units. These units are to
be configured as Mini-terminal Access Controllers (MINI-TACs),
Host Front End Processors (HFEPs) or Terminal Emulation
Processors (TEPs). The contract also includes optional
production in the amount of $14,109,268. The schedule calls for
the development to be completed by September of 1985 with
production units to be available 7 months later. RFP
