Terminal System Diagnostics

There is described herein a technique for performing failure detection and diagnosis remotely. The technique has particular application to those computing facilities wherein there are a great many terminals, such as in the order of 1000 or more.

In considering the technique, let there be assumed that a computing system has in the order of 1000 to 10,000 terminals. The primary function of this system can be the transferring and storing of data, process control, scientific computation, etc. Let it be further assumed that the terminals exhibit a range of sophistication of behavior from primitive such as, for example, being able only to receive and transmit data, to fairly intelligent such as, for example, being the equivalent of a slow ALU (arithmetic logic unit). These terminals are, of course, subject to failure, not only in their electronics but also in their mechanical components.

With the technique described herein, in the case of failures in the logic, particularly if the logic is designed in the Universal Functional Object mode as described in the publication, "Computer Design Architecture II", J. P. Roth, RA 48, March 1, 1973, pp. 114-133, published by the IBM Corporation, the failing circuit or line is disconnected and a general purpose spare appropriately activated, and connected so as to replace the failing element. The latter operations are achieved by appropriately modifying the "connection vector". Failures are so detected, diagnosed, and replaced until the reservoir of spar...
