Abstract: Embodiments can provide a smart interface card control method and apparatus. Under such a method or apparatus, after a smart interface card is inserted into a smart interface card slot of a host, a virtualized management interface can be registered with the host using a protocol stack of a preset type. A virtual link can be created to connect a baseboard management controller management interface to the virtual link. A management address configuration instruction sent by the host can be received for configuring a management address of the management interface. A control instruction sent by the host by using the management address can be received, and the control instruction to the BMC management interface can be sent by using the virtual link. According to the foregoing smart interface card control method and apparatus, scalability of the smart interface card can be improved.

Abstract: The present disclosure discloses a method and apparatus for processing network protocol stack data. The method includes: extracting, from a to-be-processed data packet, an identifier used to indicate a data flow to which the to-be-processed data packet belongs; when a pre-generated rule matching table includes the identifier, processing, according to a protocol-stack layer jump processing policy that is corresponding to the identifier and that is in the rule matching table, the to-be-processed data packet on a target layer indicated by the protocol-stack layer jump processing policy. By using the method and apparatus in the present disclosure, unnecessary processing may not be performed on some data packets that do not need to be processed on all protocol-stack layers, so as to reduce or even avoid unnecessary consumption of computing resources and transmission resources.
