                    CBI Networking Activity at MITRE

     This RFC is in response to Tom O'Sullivan's probe for comments

on Computer Based Instruction. MITRE is currently doing some pre-

liminary work in the area,at the present time limited to use of CAI-

related network resources.

     The most expedient way for me to respond is by attaching excerpts

taken from a recent status report prepared for internal MITRE use,

intended for staff not generally familiar with the ARPANET. Comments

directed at specific items in Tom's attachment will follow in a future


     We welcome comments on our activities and would like to partici-

pate in any CBI dialogs that take place.

                                                                [Page 1]
                       STATUS OF IR&D TASK 9780


     MITRE/Washington became a node in the ARPA computer network in

September 1971 when a Terminal Interface Message Processor (TIP) was

installed. Since that time MITRE's use of the network has largely

been supported by IR&D funds. The objectives of the IR&D Network

Studies are:

     (a)  to promote the use of the network resources in an

          operational mode within MITRE to increase the computer

          capabilities available for supporting sponsor's work;

     (b)  to use the ARPANET itself as a research tool for

          conducting computer networking experiments; and

     (c)  to demonstrate the use of ARPANET resources to extend

          the capabilities of existing systems.

     Specifically, the proposed objectives are:

     (1)  to select ARPANET resources that can be used to support

          identified MITRE projects and to demonstrate how these

          resources can be used;

                                                                [Page 2]
     (2)  to use the ARPANET as a research tool to conduct data

          sharing experiments to study techniques for data handling

          on a computer network; and

     (3)  to demonstrate the feasibility of using remote

          resources on the ARPANET to augment the capabilities

          of the TICCIT* system.

*The principle use of the TICCIT (Time-Shared Interactive Computer
 Controlled Information Television) system has been for Computer
 Assisted Instruction (CAI). A TICCIT/CAI system is currently being
 developed by MITRE under a National Science Foundation (NSF) grant.

                                                                [Page 3]

     The IR&D Network Studies and Experiments project requires soft-

ware development on selected ARPANET Host computers and extensive

exercising of network resources. The approach taken to fulfill the

project objectives involves effort in three areas.

     Task area I is designed to build up ARPANET usage by MITRE.

Task II involves conducting data sharing experiments on the network

utilizing software being built by MITRE at several network sites.

Task III is intended to demonstrate the use of CAI-related network

resources to augment the TICCIT/CAI system.

     The specific activities involved in each task area are discussed


2.3  Task III - Demonstrate Extensions to TICCIT System Capabilities
     That Are Possibly by Drawing on ARPANET Resources

     The structure of the ARPANET is such that it is technically

possible to combine resources on the network to form a "distributed

system." A first step in this direction would be to use network

resources to augment a special-purpose system connected at one of the

nodes. The special-purpose system would serve as the vertex of the

distributed system, dynamically drawing on network resources to

perform specific functions.

                                                                [Page 4]
     The TICCIT/CAI system is a good candidate for demonstrating the

feasibility of the concept of a distributed system. However, rather

than initially connecting TICCIT to the network, resources on the

network will first be used to demonstrate how they could augment the

capabilities of TICCIT

     Task III is organized as three subtasks to demonstrate that the

range of curriculum material can be extended, to demonstrate that the

TICCIT/CAI system can be supplemented with specialized CAI systems

that use AI techniques, and to demonstrate that TICCIT system resources

and capabilities can be augmented by using computing and storage

resources available on the network.
