Ethernet TCP/IP as control/neutral network

I was going through March edition of InTech. Articles Wide terrain in LAN by Kevin and Roland & Dream come true or nightmare? by William have potential scope for discussion.

I guess , in instrumentation and Automation world , hunt for a better network never stops. We try to have a network that is reliable , redundant , light (minimum message overhead), neutral , open , fast , cheap etc..etc.. Recommendations and restrictions are there for every cause like interference , collision , optimised routing , quick recovery , open , security etc.. Industry developed so many proprietary networks and applications by spending expensive resources. But when trend started to make things on open standards , Ethernet TCP/IP stood as best option. On the other hand field bus technologies like Profibus , FF etc and neutral applications like OPC cropped up. Later on to bring field buses onto plant network TCP/IP extensions demanded MODBUS over TCP/IP , PROFINET , HSE Ethernet/IP etc.. At some other corner a new dish by name wireless is getting prepared.

so the result is industrial networks are on IEEE x802.xx race... RACE is ON , who is going to Win?
