1. A real time data imaging network system comprising:
- a plurality of real time stations, each of said stations having memory means; and
a broadcast communications network connecting said stations including means for repetitively transmitting at least one message from each of a plurality of said stations to each other of said stations said at least one message having a uniquely identified block of data with each repetition containing a current data image, said each other of said stations including means for receiving said at least one message and storing means for storing each repetition of said uniquely identified block of data in a same unique address space in said memory means, said each other of said stations also including means for alternatively receiving another message from one of said stations, with said other message having one of a TCP/IP protocol and a UDP/IP protocol.

Abstract
A computer network system repetitively distributes messages including uniquely identified blocks of real time data containing a current data image over a broadcast communications network to all real time stations for storage of each repetition of each entire block of data directly in station memory at a unique address space assigned to that uniquely identified block of data. The real time stations receive the blocks of data and alternatively receive other messages from the real time stations. The other messages have a recognized standard protocol, such as the TCP/IP or UDP/IP protocol of the Internet Protocol Suite.

11. A method of distributing data in a real time data imaging network system comprising:
- a plurality of real time stations, each of said stations containing a central processing unit, a memory and a network interface; and
a communications network interconnecting said stations through said network interfaces, said method comprising the steps of;operating said central processing unit in each of said stations to repetitively assemble data into uniquely identified blocks of data containing a most recent data image; broadcasting each repetition of each uniquely identified block of data assembled by each of said stations over said communications network in a message to every other of said stations; receiving said message and storing in said memory at each of said every other of said stations each repetition of each uniquely identified block of data received from other of said stations over said communications network in a same unique address space in said memory for each uniquely identified block of data; employing another message having one of a TCP/IP and a UDP/IP protocol; and alternatively receiving said other message from one of said stations. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A real time distributed process control system comprising:
-
a plurality of real time stations, each of said stations having memory means; and a real time broadcast communications network connecting said stations including means periodically transmitting at least one message from each of a plurality of said stations to each other of said stations said at least one message having a uniquely identified block of data with each periodic transmission containing a current data image, said each other of said stations including means for receiving said at least one message and storing means for storing each periodic transmission of said uniquely identified block of data in a same unique address space in said memory means, said each other of said stations also including means for alternatively receiving another message from one of said stations, with said other message having one of a TCP/IP protocol and a UDP/IP protocol. - View Dependent Claims (19)
