[edit] INDUSTRIAL REALTIME ETHERNET
Linux preempt RT seems a good choice for developing realtime internet networks
Well known name of the moment :
- profinet
- powerlink
- ethercat
- modbus tcp
- ethernet/ip
..... gateways to older well known fieldbuses : canopen, ...
I will not tell if one is better or not than another, this completely depends on YOUR requirements.
The today's problem is that we will need a combination of at least two networks in our applications for some reasons... (retrofitting applications, migrating to new protocols , availability of products ....)
This is why we would need to develop : The Opensource realtime network industrial framework , a software gateway framework running linux rt preempt able to dialog with any bus (selected at compilation). using standard Ethernet hardware. this framework is intended being used by automation/embedded plc's
I encourage everybody beginning the discussion here , to create the project .
a quick TODO list , contributors welcomed , I know some people are already on the way :
- measurement and publication of timing spent to transverse the linux kernel network stack needed in order finding where optimisations are needed.
- searching for the best software architecture in order being able driving realtime ethernet protocols (ace api ? ,other ...)
- optimisations of network drivers : most ethernet linux drivers do not provide the ability to use hardware features available in the chipsets. (eg UPD checksum ..)
