The present specification provides a method for realizing ECMP traffic load balancing and electronic equipment, the method being applied to a forwarding device, the method comprising: monitoring a bandwidth occupancy rate of each link allocated to a plurality of data streams with the same target address, the forwarding device allocates the links to the plurality of data streams with the same target address based on a Hash algorithm; under the condition that the bandwidth occupancy rates of all the links are unbalanced, the types of data streams in the links with the bandwidth occupancy rates exceeding a threshold value are identified, and the types of the data streams comprise elephant streams; the identified elephant flow is switched to a light-load link according to an ACL rule, the ACL rule is configured according to quintuple information of the identified elephant flow, and the light-load link is a link with the bandwidth occupancy rate not exceeding the threshold value. According to the method, the probl
