1. A routing management method, comprising:
obtaining, by a controller, network topology information of a network side;
calculating, by the controller, path information of a Segment Routing-Traffic Engineering (SR-TE) instance to be created, based on the network topology information, and sending the path information to a network-side head node; wherein the path information comprises segment list information and Entropy Label (EL) insertion position information; and
creating, by the controller, the SR-TE instance from the network-side head node to a tail node, and
wherein the EL insertion position information comprises whether to insert the EL and one or more positions into which the EL to be inserted.
