 Packet Latency
 ==============
 
-.. todo::
-    Introduction
+DPDK Testpmd and L3fwd latency results are generated based on the test
+data obtained from |csit-release| NDR-PDR throughput tests executed
+across physical testbeds hosted in LF FD.io labs: 3n-hsw, 3n-skx, 2n-
+skx, 2n-clx, 3n-dnv, 2n-dnv, 3n-tsh, 2n-tx2.
+
+Latency by percentile distribution plots are used to show packet latency
+percentiles at different packet rate load levels: i) No-Load latency
+streams only, ii) Low-Load at 10% PDR, iii) Mid-Load at 50% PDR and iv)
+High-Load at 90% PDR.
+
+For more details, see :ref:`latency_methodology`.
+
+Additional information about graph data:
+
+#. **Graph Title**: describes tested DUT packet path.
+
+#. **X-axis Labels**: percentile of packets.
+
+#. **Y-axis Labels**: measured one-way packet latency values in [uSec].
+
+#. **Graph Legend**: list of latency tests at different packet rate load
+   level.
+
+#. **Hover Information**: packet rate load level, stream direction
+   (East-West, West-East), percentile, one-way latency.

-    Required per test case data set size is **10** and for DPDK tests
-    this is the actual size, as all scheduled test executions completed
-    successfully.
