+- ``ring_mt_rts``

+ For underlying **rte_ring** both producer and consumer operate in
+ multi-thread Relaxed Tail Sync (RTS) mode. For more information please

+- ``ring_mt_hts``
+
+ For underlying **rte_ring** both producer and consumer operate in
+ multi-thread Head-Tail Sync (HTS) mode. For more information please

+
+For 'classic' DPDK deployments (with one thread per core) the ``ring_mp_mc``
+mode is usually the most suitable and the fastest one. For overcommitted
+scenarios (multiple threads share same set of cores) the ``ring_mt_rts`` or
+``ring_mt_hts`` modes usually provide a better alternative.

synchronisation modes please refer to: :doc:`../prog_guide/ring_lib`.
