+         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.
