Digital computer for determining a combined tag value from tag values selectively incremented and decremented reflecting the number of messages transmitted and not received
First Claim
1. A digital computer comprising:
- a plurality of message generating nodes interconnected by a routing network;
A. said routing network for transferring messages among said message generating elements;
B. each message generating node including;
i. a message processing element for generating messages, each message including a tag field containing a tag value for transmission over said routing network, and for receiving messages from said routing network; and
ii. a message counter whose contents are selectively incremented and decrement in response to the tag value of the tag field of transmitted and received; and
C. a combine network for performing a combine operation in connection with the lag values of the message counters of said message generating nodes to determine a combined tag value reflecting the number of messages which have been transmitted by said message generating nodes over the routing network which have not been received by said message generating nodes.

Abstract
A digital computer includes a plurality of processing elements, a command processor, a diagnostic processor and a communications network. The processing elements each performs data processing and data communications operations in connection with commands. The processing elements also performing diagnostic operations in response to diagnostic operation requests and providing diagnostic results in response thereto. The command processor generates commands for the processing elements, and also performs diagnostic operations in response to diagnostic operation requests and providing diagnostic results in response thereto. The diagnostic processor generates diagnostic requests. The communication network includes three elements, including a data router, a control network and a diagnostic network. The data router is connected to the processing elements for facilitating the transfer of data among them during a data communications operation. The control network is connected to the processing elements and the command processor for transferring commands from the command processor to the processing elements. The diagnostic network connected to the processing elements, the command processor and the diagnostic processor for transferring diagnostic requests from the diagnostic processor to the processing elements and the command processor and for transferring diagnostic results from the processing elements and the command processor to the diagnostic processor.
