+	  The Lustre network layer, also known as LNet, is a networking abstaction
+	  level API that was initially created to allow Lustre Filesystem to utilize
+	  very different networks like tcp and ib verbs in a uniform way. In the
+	  case of Lustre routers only the LNet layer is required. Lately other
+	  projects are also looking into using LNet as their networking API as well.
