COMMUNICATION APPARATUS, CONTROL APPARATUS, AND COMMUNICATION SYSTEM
First Claim
1. A communication apparatus for transmitting and receiving data, the communication apparatus being configured to:
- store assertion information in which a failure detection condition is registered, the failure detection condition including information for identifying data that is not to be received during normal operation;
refer to the assertion information when data has been received from another communication apparatus;
judge whether or not the received data satisfies the failure detection condition registered in the assertion information; and
detect a failure when it is judged that the received data satisfies the failure detection condition registered in the assertion information.

Abstract
A communication apparatus for transmitting and receiving data is configured to: store assertion information in which a failure detection condition is registered, the failure detection condition including information for identifying data that is not to be received during normal operation; refer to the assertion information when data has been received from another communication apparatus; judge whether or not the received data satisfies the failure detection condition registered in the assertion information; and detect a failure when it is judged that the received data satisfies the failure detection condition registered in the assertion information.

14. A communication system, comprising:
-
a plurality of communication apparatuses configured to transmit and receive data; and a control apparatus configured to control a network constructed from the plurality of communication apparatuses, each of the plurality of communication apparatuses being configured to; store assertion information in which a failure detection condition is registered, the failure detection condition including information for identifying data that is not to be received during normal operation; refer to the assertion information when data has been received from another communication apparatus, judge whether or not the received data satisfies the failure detection condition registered in the assertion information; and detect a failure when it is judged that the received data satisfies the failure detection condition registered in the assertion information, the control apparatus being configured to; manage the assertion information stored in the plurality of communication apparatuses; and set the assertion information in the plurality of communication apparatuses.
