Arrangement and method for connecting a processing node in a distribution system
First Claim
1. An arrangement for connecting a node in a distributed system containing fail-uncontrolled nodes, the arrangement comprising:
- receiver means for receiving signals from another node of the system, and node guardian means coupled to the receiver means for controlling reception of signals thereat so as to reduce reception of uncontrolled transmission from another node of the system.

Abstract
An arrangement and method for interconnecting fail-uncontrolled processor nodes in a dependable distributed system. A node has a bus guardian with input switches which act in combination with a logic element as an input multiplexer under the control of a control unit. This provides the advantage of transferring the problem of fault containment from the output interface of a potentially faulty processing node to the input interface of fault-free processing nodes. By doing so, problems encountered by spatial proximity faults or functional dependencies within a faulty processing node that may jeopardize fault containment at its output interface are mitigated.
