Abstract
Information is transmitted to a network by a system which receives data from a first processor into a first FIFO and from a second processor into a second FIFO. Data exiting the first FIFO is discarded. As data is received into second FIFO, data exiting the FIFO is transferred to the network. When and end-of-message indication is detected in the received data, the contents of the FIFOs are compared. If a miscompare occurs, transferred data from the second FIFO to the network is caused to be in error. Accordingly, a message sent to the network from the second FIFO will be rejected either by the network or by a receiving node.
