Abstract: A hybrid access gateway receives packets that are sent by a network side device and are destined for a home gateway. When detecting that congestion occurs on a first transmission link and that no congestion occurs on a second transmission link, the hybrid access gateway obtains a first committed information rate (CIR) of the first transmission link and a second CIR of the second transmission link, classifies the packets into a first-type packet and a second-type packet, and transmits the first-type packet using the first transmission link and the second-type packet using the second transmission link. By properly allocating packets transmitted on the second transmission link, the hybrid access gateway can control one-way delays of the first transmission link and the second transmission link, thereby avoiding a packet loss caused by a sequencing buffer overflow.
