WebFlow modifications The primary mechanism used in the implementation of SDN applications is the installation of flow rules on datapaths (OpenFlow instances or devices). Flow modification messages (also known as flow-mods or FlowMods) tell the datapath to add, delete, or modify a flow in its flow table. Registering flow classes WebFlow-Mod: Controller->Switch instructs a switch to add a particular flow to its flow table.
