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.
STATUS OF IR&D TASK 9780
ARPA NETWORK STUDIES AND EXPERIMENTS
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
(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;
(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.
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.
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.
