Abstract: An example data processing system includes a plurality of nodes and a controller that are connected by using an interconnection device, and the plurality of nodes includes a first node and a second node. When the second node requests to access the data processing system, the controller is configured to allocate a second node identifier to the second node. A global physical address of the second node in the data processing system is a node identifier of the second node and a physical address of the second node. The controller is further configured to send the global physical address of the second node to the first node.

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: This application discloses a cache management method, apparatus, and system, and a storage medium, and belongs to the computer field. The system includes a processor and a memory controller. The processor and the memory controller are connected through a first channel and a second channel, the first channel is used to perform a memory read/write operation, and the second channel is used to transmit event information corresponding to the memory read/write operation. The processor is configured to send event information of a first event to the memory controller through the second channel. The memory controller is configured to manage a cache storage based on the event information, and the cache storage is configured to cache a part of data that is in the memory storage. This application can improve utilization of the cache storage.

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.
