Keep Coding

I have tried to use amqpnetlite to send message peer to peer. I use this code: amqpnetlite peer to peer. my question is: should I use an amqp broker for it?
here the exact code:
string address = "amqp://guest:guest#127.0.0.1:5672";
Uri addressUri = new Uri(address);
ContainerHost host = new ContainerHost(new Uri[] { addressUri }, null, addressUri.UserInfo);
host.Open();
