 ^^^^^^^^^^^^^^^^^^^^^^^^^
 
-The server process performs the network port and data structure initialization much as the symmetric multi-process application does when run as primary.
-One additional enhancement in this sample application is that the server process stores its port configuration data in a memory zone in hugepage shared memory.
-This eliminates the need for the client processes to have the portmask parameter passed into them on the command line,

 In the same way that the server process is designed to be run as a primary process instance only,
 the client processes are designed to be run as secondary instances only.
-They have no code to attempt to create shared memory objects.
-Instead, handles to all needed rings and memory pools are obtained via calls to rte_ring_lookup() and rte_mempool_lookup().
-The network ports for use by the processes are obtained by loading the network port drivers and probing the PCI bus,
-which will, as in the symmetric multi-process example,
-automatically get access to the network ports using the settings already configured by the primary/server process.

+The routing used is very simple, all packets received on the first NIC port are transmitted back out on the second port and vice versa.
