Abstract: Embodiments of the present application disclose a message processing method, apparatus, and system, which are applied to SDN. An application sends a first message to a controller, and the message includes service content used to describe a service requirement. The service content includes target information and operation information. The application receives a second message sent by the controller. A payload of the second message includes solution information of at least one solution used to implement the service content. The application obtains the solution information of the at least one solution based on the payload of the second message. Therefore, a service requirement is converted into a control requirement between an application plane and a control plane.

Abstract: This application discloses a method for forwarding a packet in a data center network. A first device obtains an original packet, and adds a first source label to the original packet to obtain a first packet. The first source label includes a forwarding type, an indication field, and an interface sequence. The forwarding type indicates that the first packet supports source label forwarding, the interface sequence indicates a first source label forwarding path of the original packet, and the indication field indicates information that is about an outbound interface and that should be read from the interface sequence. The first device sends the first packet to a next-hop switch through the outbound interface corresponding to the first source label forwarding path. The next-hop switch receives the first packet, and forwards the first packet based on the first source label.

Abstract: One example method includes receiving network topology information delivered by a topology manager, where the data center includes a plurality of servers, a plurality of electrical switches, and at least one optical cross-connect device. A data flow can be obtained. A routing policy can be configured for the data flow based on the network topology information, where the routing policy includes any one or a combination of the following routing policies: a first routing policy, where the first routing policy indicates to forward the data flow through an optical channel in the at least one optical cross-connect device; a second routing policy, where the second routing policy indicates to split the data flow into at least two sub-data flows for forwarding; or a third routing policy, where the third routing policy indicates to forward the data flow through an electrical switch of the plurality of electrical switches.
