1. A packet forwarding method, applied to a forwarding device, comprising:
receiving a target packet carrying source period information which comprises a predetermined period length corresponding to a sending period for a source device sending the target packet to the forwarding device and a source period identification of the sending period;
determining a corresponding forwarding period identification according to the predetermined period length and the source period identification; and
forwarding the target packet in a forwarding period corresponding to the forwarding period identification, with a length of the forwarding period being the same as the predetermined period length,
wherein the determining a corresponding forwarding period identification according to the predetermined period length and the source period identification comprises:
selecting a corresponding candidate period length from a plurality of different candidate period lengths through matching according to the predetermined period length, taking the selected candidate period length as a matched period length, the matched period length is equal to the length of the forwarding period, finding a corresponding egress interface period identification based on the matched period length by looking up a multi-period mapping table with the source period identification being used as an ingress interface period identification, and taking the egress interface period identification as the forwarding period identification; wherein the multi-period mapping table records a mapping relationship between an ingress interface period identification and an egress interface period identification corresponding to each of the plurality of different candidate period lengths.
