21 /* Logical_Flow table translation to OpenFlow
22 * ==========================================
24 * The Logical_Flow table obtained from the OVN_Southbound database works in
25 * terms of logical entities, that is, logical flows among logical datapaths
26 * and logical ports. This code translates these logical flows into OpenFlow
27 * flows that, again, work in terms of logical entities implemented through
28 * OpenFlow extensions (e.g. registers represent the logical input and output
31 * Physical-to-logical and logical-to-physical translation are implemented in
32 * physical.[ch] as separate OpenFlow tables that run before and after,
33 * respectively, the logical pipeline OpenFlow tables.
