FRDM - k64f ethernet connection


I was thinking about one school project- modal analysis- and i'm not sure if my solution would works. My thought is to connect- for example-two FRDM-k64f boards via ethernet to switch and then to PC. On FRDM-k64f board is accelerometer. I need data from accelerometer with time stamp and with maximal synchronization time error about 100us ( u = micro ). Is there any way how to achieve lesser time error than 100us with common switches, NIC... Does anybody know about similiar project like this?

Thank you for your help.

Transmit it with a timestamp, then use that timestamp for whatever reason you want it at 100us accurate. Ethernet was never intended for this role.
