+      <p>This project provides:</p>
+
+      <ul>
+	<li>A new driver (<tt>if_ptnet</tt>) for a paravirtualized network
+	  device, modeled after the netmap API.  The driver supports
+	  multi-queue netmap ports, and it is able to work both in netmap
+	  mode and in normal mode.</li>
+
+	<li>The emulation of the <tt>ptnet</tt> device model as a module
+	  of the <tt>bhyve</tt> hypervisor.</li>
+      </ul>
+
+      <p>The <tt>ptnet</tt> device and driver has been introduced to
+	overcome the performance limitations of TCP/IP networking between
+	bhyve VMs.  Prior to this work, the most performant solution for
+	VM-to-VM intra-host TCP communication provided less than 2 Gbps TCP
+	throughput.  With <tt>ptnet</tt>, in the same VM-to-VM TCP
+	communication scenario, it is possible to obtain up to 20 Gbps.</p>
