Abstract: A data processing method includes sending, by a network interface card of a first device, a request packet to a second device. The request packet is used to request to read data in a destination storage area of the second device. The network interface card receives a response packet that is sent by the second device in response to the request packet. The response packet includes the data. The network interface card initiates, based on the response packet, direct memory access to a storage address to write the data into a memory area to which the storage address points. The first data does not need to be cached in a memory of the network interface card. Bandwidth resource usage and storage space usage of the memory of the network interface card can be reduced.

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.
