Claim 0:
1. A method implemented by a path computation node and comprising:
determining a first segment routing-best effort (SR-BE) forwarding path from a first node to a second node in a first virtual network, wherein the first node is a start node of data transmission, and wherein the second node is a destination node of the data transmission;
determining a second SR-BE forwarding path from the first node to the second node in a physical network, wherein the first virtual network is over the physical network; and
determining, when the first SR-BE forwarding path completely overlaps the second SR-BE forwarding path, the first SR-BE forwarding path as a target forwarding path; or when the first SR-BE forwarding path does not completely overlap the second SR-BE forwarding path:
determining a first segment routing-traffic engineering (SR-TE) forwarding path according to the physical network and the first virtual network, and
determining the first SR-TE forwarding path as the target forwarding path.
