Now I'm working in a system that has two machines communicate with each others using a protocol called tacfire net protocol, I have no information about how this protocol works or its message format I do did a lot of searches about this protocol but I couldn't find anything
So anyone could help And if it's not the appropriate place to ask please gently tell me the right place.

  • Unfortunately, questions about protocols above OSI layer-4, and questions that are trivial/irrelevant to modern networking are off-topic here.

I am certainly no expert here but my searching found ...

There is a U.S. military protocol called TACFIRE protocol, which appears to be a fixed format textual representation of battlefield events. It appears to be named after the TACFIRE military computer (wikipedia) Could that be what you're looking for?

A report on converting this to/from other formats is available from the George W. Jr, 1995, "Automated Translation of Bit-Oriented Messages (BOMs) into Data Kernel Representations (DKRs)", U.S. Army Research Laboratory, 1995. Available online at http://www.dtic.mil/dtic/tr/fulltext/u2/a293147.pdf

There is also good description of it (including some transport level description) here Jacques,R G, 1984, "Real-Time Message Process Simulation Capability.", http://www.dtic.mil/get-tr-doc/pdf?AD=ADA149017

The U.S. Defense Technical Information Center has many documents about it, and the documents show fascinating early uses and motivation behind TCP/IP. Search here http://www.dtic.mil/dtic/

Quick reading of those documents show they call "TACFIRE protocol" pretty much anything from L1 to L7 which is used on the TACIFRE computer.

Any use?

  • thanks a lot but could you please upload this file again dtic.mil/get-tr-doc/pdf?AD=ADA149017 corrupted format after downloading
