That translates a bit awkwardly into English. There really aren't people here to fix your project issues. If you have a relationship with ST, or their distribution chain, perhaps you can discuss your needs with an FAE. ST also maintains a list of contractors and consultants.

You'll probably want to review as many Ethernet examples as you can find, and probably add some robustness and recovery methods of your own to handle situations where the hardware or connectivity gets into problematic states.
