Abstract: A file page table management method. The file page table management method is applied to a storage system in which a file system is created in a memory. According to the file page table management method, a mapping manner of a file page table can be dynamically adjusted based on an access type of an access request for accessing the memory, thereby improving memory access efficiency and saving memory space.

Abstract: A data packet processing method, Where the method includes matching a received data packet in a flow table, and determining the received data packet as a newly-established data packet, where the newly-established data packet is a data packet that needs to be reported to a controller to determine a processing manner, determining a target priority of the newly-established data packet, and reporting the newly-established data packet to the controller according to the target priority. Priorities of data packets entering an OPENFLOW switch are determined, and for unsuccessfully matched data packets, a data packet having a high priority is forwarded preferentially according to the priorities, thereby ensuring that data having a high priority is not discarded.

Abstract: An OFS in-band communication method and an OFS are disclosed. The method includes: receiving an LLDP data packet; creating a controller list entry or updating a controller list entry when it is determined, by using a role sub-field, that a sender type of the received LLDP data packet is OFC; acquiring a first-time TCP handshake packet used for establishing a TCP connection, and checking, according to a destination MAC and a destination IP that are carried in the TCP handshake packet, whether a corresponding controller list entry exists in a controller list; and if yes, updating a flow entry according to the MAC, the IP, and the in_port in the corresponding controller list entry in the controller list, so that an OFS can forward, by using a flow table, a packet to be sent to an OFC to the OFC.
