Abstract: The application discloses a method for establishing a forwarding path in a network, where the network includes a SC and a plurality of DCs, the SC manages the plurality of DCs, each of the plurality of DCs manages one domain, and the method includes: receiving, by the SC, a service request message; selecting, by the SC, a latency distribution manner based on the service request message; dividing, by the SC, a first latency into a plurality of latency periods; sending, by the SC, each of the plurality of latency periods to a DC corresponding to the latency period, and triggering each of the plurality of DCs to establish a forwarding path segment in the domain managed by the DC; and connecting, by the SC, the plurality of forwarding path segments established by the plurality of DCs, to form a forwarding path.
