1. You are requested to initiate a four-month contract with Stanford
Research Institute for a study related to the design and specification of
a computer network. The work should be in accordance with the con-
tractor's proposal No. ESU 67-92, "A Study of Computer Network De-
sign lOararnotors ", dad Novernbor 7, 1967, with work statement as
follows:
a. The contractor will study the effects of selected netxvork tasks
upon Interface Message Processors (IMP's) and the communication
facilities serving a highly responsive network of computers. Among
the tasks to be studied are:
(1) The coding of the information exchanged between the IMiø's
(e.g., USACSII rs. non-USACSII, transparent binary trans-
mis sion)
(2) Acknowledgement procedures (e.g., message block for-
mation, restraint of message flow)
(3) Operational procedures (e.g., user access validation and
control, recovery from abnormal conditions)
b. The effects of alternative design choices will be characterized
in terms of IMP computational capacity, storage capacity, special
hardware requirements, and loading of the communication facilities.
c. In carrying out this study, the contractor will communicate vith
other ARPA contractors wvho are potential participants in such a
network.

ARPA Order No. 1137
2. The study should commence as soon as possible, not later than
JanUary 1, 1968. The total price is estimated to be $19, 586; an
additional amount of $214 is provided for ARO-D expenses in connection
with monitoring this contract.
3. This Order makes available $19,800 under appropriation and
account symbol "97X0400. 1301 Research, Development, Test and
]Evaluation, Defense Agencies", for obligation by ARO-D on behalf
of the Advanced Research Projects Agency, only for purposes necessary
to accomplish the work specified herein. These funds are immediately
available for direct obligation. The funds made available herein are
not for the construction of facilities.
4. A final technical report should be prepared and submitted in
memorandum dated September 13, 1966, subject: "ARPA Orders -
General Requirements."
5. It is requested that two copies of each contract or contract modi-
fication awarded as a result of this Order be submitted to the Director,
ARPA. In transmitting such docun/ents, specific reference should be
made to ARPA Order No. 1137.
6. The General Requirements as stated in the attachment to the
