Hi Pengyu,

1. the USRPs are full duplex capable, so you can get away with just  
using two.
2. You should not use a router. A switch would be ok. Please note that  
you can’t get more than 1Gb ~= 32MS/s over the single Gigabit link  
between your PC and the switch, so it’s better to use a PC with two  
network cards connected to one USRP each, so you get more bandwidth.

Greetings,  
Marcus
