The invention provides a data forwarding method and device and service providing side edge equipment, and relates to the technical field of communication, the method is applied to a first PE, the first PE is in communication connection with two or more second PEs, and the two or more second PEs are located in the same multi-homing network; the method comprises the following steps: acquiring stateinformation of each second PE, wherein the state information comprises one or more of the CPU residual utilization rate of the second PE, the minimum residual bandwidth amount of the link where the second PE is located and the bit error rate of the link where the second PE is located; determining a data allocation proportion of each second PE according to the state information; and allocating theto-be-forwarded data to each second PE according to the data allocation proportion, so that the second PE forwards the allocated data. The reliability of data forwarding can be effectively improved.
