Connect 2 Due on ethernet

Hello,

I use one Arduino Due with shield w5200 with server web (on SD card) and NTP for Clock. I wan't to connect a another arduino du with w5200 on my network. How to communicate with this to arduino Due (I wan't to transmit and receive data on the 2 arduino)

thanks

UDP will be the easiest and fastest if both are on the same localnet.
