Forwarding Path Determining Method, Apparatus, and System

A forwarding path determining method includes: determining, by a path computation node, a first SR-BE forwarding path from a first node to a second node in a first virtual network; determining a second SR-BE forwarding path from the first node to the second node in a physical network; and when the f...

Zusammenfassung:A forwarding path determining method includes: determining, by a path computation node, a first SR-BE forwarding path from a first node to a second node in a first virtual network; determining a second SR-BE forwarding path from the first node to the second node in a physical network; and when the first SR-BE forwarding path completely overlaps the second SR-BE forwarding path, determining the first SR-BE forwarding path as a target forwarding path from the first node to the second node in the first virtual network; or when the first SR-BE forwarding path does not completely overlap the second SR-BE forwarding path, determining, by the path computation node, a first SR-TE forwarding path according to the physical network and the first virtual network, and determining the first SR-TE forwarding path as a target forwarding path from the first node to the second node in the first virtual network.
