I have a PC with two PCIe express cards each of which has four Ethernet connections. I connect 6 USRP N210 to them. For shorter transmissions, like 8 samples, I can do 25Msamp/sec on all simultaneously. But I have issues with latencies. I am using UHD driver version 3.3.2 still. I spent two

There are lots of different ways. One example would be to simply connect them all to a switch, along with your host. Assuming the aggregate bandwidth doesn't exceed what the host's network card or switch can handle you'll be fine. You could also, as you mentioned, have a single host with 8 netwo
