Abstract: A method for optimizing data access performance, which is applied to an intermediate device, is described. The intermediate device is a network device between a client and a server side, there are one or more clients and one or more server sides. The method includes the intermediate device parsing a received first packet to obtain a feature of the first packet, where the first packet is from a terminal on which one of the clients is located, the first packet is used to request data from one of the server sides, the feature indicates the data requested by using the first packet, and the feature is carried in a part that is of the first packet and that corresponds to application layer data. The method may also include, when the intermediate device stores the data requested by using the first packet, sending the data requested by using the first packet to the terminal.

Abstract: A method and an apparatus for processing a forwarding entry are provided. The method for processing a forwarding entry includes: receiving an entry operation packet through a first data channel; parsing the entry operation packet to obtain forwarding entry operation information; and performing a target operation on a memory based on the forwarding entry operation information, where the target operation includes adding an entry, deleting an entry, or modifying an entry.

Abstract: This application discloses a packet forwarding method and apparatus, a device, and a storage medium. The method includes: obtaining packet configuration information, where the packet configuration information includes a packet parsing rule; parsing a received target packet based on the packet configuration information to obtain a target packet feature; obtaining a packet forwarding rule corresponding to the target packet based on the target packet feature; and forwarding the target packet according to the packet forwarding rule corresponding to the target packet. Because packet features of different service data are different, the different service data is distinguished based on the different packet features, and is forwarded according to different forwarding rules. This implements forwarding control of the different service data, improves service data forwarding efficiency and adjustment precision, and avoids low service data transmission efficiency and incapability of splitting the different service data.

Abstract: Provided is a method and a network apparatus in a cloud infrastructure. The network apparatus includes a processor, and a memory coupled to the processor, the memory for storing computer instructions that, when executed by the processor, cause the processor to generate a resource abstraction layer relating a network cluster including a first server architecture with a first resource set and a second server architecture with a second resource set, to generate an orchestration layer configured to receive a packet flow request and, in response to the packet flow request, schedule virtual network resources based on the resource abstraction layer for servicing a packet flow, and to deploy the virtual network resources to receive and service the packet flow.
