I want to connect USRP N210 with my ML605 (Virtex-6) board through
ethernet. But I don’t know how USRP N210 work with ethernet.
a) It is said the USRP communicate with the host using UDP/IP. But what
is the UDP payload?
b) There is something called VRT in GNU-radio. Is the VRT package in UDP
package?
c) Does anyone know how USRP2 communicate with the host? Or is there
some documents can tell me that?
I got all of the ethernet frames when the USRP N210 is sending data.
This is the first several frames:
host MAC: 10:bf:48:bc:ab:be
USRP MAC: a0:36:fa:25:39:fe

ARP is in this ethernet frame

I don’t know what the UDP payload is.
Thank you.
