Abstract: The present disclosure relates to a traffic scheduling method and apparatus, and an electronic device and a computer-readable medium. The traffic scheduling method comprises: acquiring, by means of a traffic egress switch, a current packet to be sent, and forwarding the packet to a programmable switch, which is connected to the traffic egress switch; acquiring, by means of the programmable switch, a communication parameter corresponding to the packet, and determining a target port identifier of the packet according to the communication parameter; marking the packet according to the target port identifier of the packet, and returning the marked packet to the traffic egress switch; and determining, according to the target port identifier, a target output port corresponding to the packet from among a plurality of output ports of the traffic egress switch, and sending the packet by means of the target output port.
