Remote switching a communication device in a communication network
First Claim
1. A communication network comprising:
- a plurality of nodes;
a communication medium for communicating between the plurality of nodes; and
communication diode means for controlledly enabling/disabling access of at least one of the plurality of nodes to the communication medium by control means external to the at least one of the plurality of nodes, such that isolation of a faulty node and/or subnets within the communication network can be achieved.

Abstract
A communication network (300, 400), and (D1-D3, D11-D13, 500) for use therein, comprising a plurality of nodes (N1-N4, N11-N13), a communication medium for communicating between the plurality of nodes; and communication diode arrangement(s) (D1-D3, D11-D13, 500) for controlledly enabling/disabling access of the node(s) to the communication medium by control external to the node(s). The communication diode arrangement(s) can enforce fail-silence in the time domain within a distributed computer system, showing resilience against spatial proximity faults. The communication diode arrangement(s) may be controllable not only by time but also by commands embedded in frames. This allows isolation of a faulty processing node and/or subnets within an embedded distributed real-time communication system, such as for automotive by-wire applications (FlexRay, TTP), under consideration of spatial proximity faults.
