Does anyone on here have any experiences to relate about implementing any of the above protocols. How much effort did it take, how much processor and memory resource and how accurate a timing correlation can be achieved across nodes on the network. I would also be interested in knowing if some of the schemes used other timing synchronisation distribution schemes in addition to these protocols.
I am looking at a situation with approximately 50,000 sensors, some time critical control requirements and and a need to ensure that all the data is on a closely relateable timebase.
