Multicast message suppression method, device and equipment based on SDN (Software Defined Network) and storage medium

Disclosed are an SDN-based multicast message suppression method, apparatus and device, and a storage medium, which relate to the technical field of communications, are applied to an SDN controller, and comprise: acquiring respective broadcast requests of a first network element node device of a transmitting end and a second network element node device of a receiving end forwarded according to a flow table policy; analyzing the broadcast request through a deep packet inspection technology, and updating a flow table strategy by using data obtained after analysis to obtain a target flow table strategy; and based on the target flow table strategy, forwarding a unicast message obtained by converting the multicast message sent by the sending end through the first network element node equipment to the second network element node equipment, so that the second network element node equipment converts the unicast message into the multicast message and sends the multicast message to a receiving end. Through the technical
