Abstract: This application discloses a packet processing method, comprising: A storage server receives a first packet, where the first packet includes a first service layer and a check value of the first service layer, and the first service layer includes payload data. The storage server obtains a check value of the payload data through calculation based on the first service layer and/or the check value of the first service layer. The storage server sends a second packet to a gateway device, where the second packet includes a second service layer, a check value of the second service layer, and the check value of the payload data, the second service layer is obtained based on the first service layer, and the check value of the second service layer is obtained through calculation based on the second service layer and the check value of the payload data.

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: The technology of this application relates to a packet processing method, a gateway device, and a storage system, and belongs to the field of storage technologies. In this disclosure, a request for accessing a non-volatile memory express (NVMe) node is converted into a request for accessing a remote direct memory access (RDMA) node. Because a storage medium of the NVMe node is a hard disk, and a storage medium of the RDMA node is a memory, the memory can provide a faster read/write speed than the hard disk. Therefore, storage performance is improved. In addition, this helps a conventional NVMe over fabrics (NOF) storage system expand an RDMA memory pool, and improves flexibility of networking and capacity expansion of the storage system.

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.
