Il futuro dello Standard Ethernet: convergenza tra sistemi di controllo e Industrial IoT

L’IEEE 802 ha incrementato le capacità dello standard Ethernet così da garantire la convergenza di traffico IT verso il traffico OT per le operazioni di controllo time-sensitive. In questo workshop introdurremo gli ultimi sviluppi relativi all’infrastruttura Ethernet in grado di supportare sincronizzazione temporale, comunicazioni a bassa latenza e garantire una rete estremamente affidabile. Vieni a scoprire l’Ethernet di prossima generazione pronto a supportare il traffico dati deterministico.
