Abstract: A deterministic flow forwarding method and apparatus, a storage medium and an electronic device are provided. The method includes: sending, by a controller, a Segment Routing (SR) policy carrying deterministic path information to an edge node of a network, wherein the SR Policy is used for instructing the edge node of the network to forward a deterministic flow according to the deterministic path information. By virtue of the above technical solution, the problem that a controller cannot implement distribution of a deterministic path by an SR Policy is solved.
