Claim 14:
15. A path computation node comprising:
a memory configured to store instructions; and
a processor coupled to the memory and configured to execute the instructions to:
determine 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;
determine 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
determine, 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:
determine a first segment routing-traffic engineering (SR-TE) forwarding path according to the physical network and the first virtual network, and
determine the first SR-TE forwarding path as the target forwarding path.
