The present invention disclose a transport control method, an access device, and a transport system. The transport control method includes: monitoring a current impairment index of a network; determining, according to a transport quality grade corresponding to the monitored current impairment index of the network, the number of redundant blocks carried in a data packet to be sent and/or a packetization duration of the data packet to be sent, where the number of redundant blocks carried in the data packet and/or the packetization duration of the data packet has a preset mapping relationship with a transport quality grade; and packetizing and sending the data packet according to the determined number of the carried redundant blocks and/or the determined packetization duration. The present invention may improve flexibility of transport control and is beneficial to appropriate adaptation to real-time dynamic changes of a network impairment condition.
