Network broadcast flow sending method and device capable of reducing occupied broadband, and storage medium

The invention provides a network broadcast flow sending method and device capable of reducing occupied broadband and a computer readable storage medium, belongs to the technical field of network communication, and solves the problems that at present, a broadcast domain is isolated mainly by dividing VLANs, when one VLAN is relatively large, one broadcast message is still propagated to a pluralityof targets, and the phenomenon of bandwidth occupation is still very serious. The method comprises the steps that an access control list ACL of network broadcast flow is configured, a VLAN is created,VLAN port information during creation is stored, and when the ACL receives a network broadcast flow request, a CPU sends the network broadcast flow to a VLAN port according to the stored VLAN port information. According to the invention, the ARP request can be dispatched and orderly sent through the CPU, the bandwidth occupied by the ARP message is reduced, the load of other equipment is reduced,the broadcast message is o
