Abstract

Data processing stations which intercommunicate with each other through time-shared multi-accessible networks (rings, loops, star networks, etc.) may require the ability to interchange information defining station status (availability, processing backlogs, etc.). This article concerns a method for providing this capability.

Station Status Determination

Data processing stations which intercommunicate with each other through time-shared multi-accessible networks (rings, loops, star networks, etc.) may require the ability to interchange information defining station status (availability, processing backlogs, etc.). This article concerns a method for providing this capability.

Software, in a station requiring information concerning the status of another station, generates a "status request message" addressed specifically to the other station. This message is sent out over the network communication facility. Recognizing its address as the unique destination, the other station operates at the "attachment hardware" (network adapter) level (i.e., without burdening software) to compose a response message containing the required internal status information. This response message is sent to the originator of the status request message suitably addressed. The returned message contains information indicating it to be a status message presented in response to a status request. The request originator recognizes such information at the hardware level and passes the status information to the respective software, enabling software and processing facilities at the respective station to assess the remote station's availability and Productivity.

With all stations on the network operating within the same prescribed format, a means of obtaining critical information is available that does not require system i...
