Abstract

The invention discloses a message processing method, network card, system, information update method, and server. The method is adopted by a message processing system comprising a first server, a first network card, and a second network card. The first network card is configured to generate reference information for use to process a subsequent message. Then, after an identifier of a target network card used in a session is updated to be an identifier of the second network card, the second network card is configured to obtain the updated identifier of a target network card in the session and the reference information. In this way, the second network card is configured to process, when the identifier of a target network card in the session is determined as the identifier of the second network card, according to the reference information, the subsequent received message in the session. Therefore, even if a link between the first network card and a switch is broken, the second network card can still obtain the reference information. In addition, since the identifier of the second network card has already been updated as the identifier of the second network card, the second network card can process the received message.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for processing messages, a network card and system, a method for updating information and a host. Background technique [0002] The network card is a kind of physical hardware configured in the host. The network card receives the packets sent by other hosts and sends them to the host, and the host processes the packets. In order to improve the reliability of the host, two or more network cards can be configured in the host, so that even if one network card fails, one of the remaining network cards can take over for the failed network card, which will not affect the performance of the host. Packets sent by other hosts are processed. [0003] As more and more packets need to be processed by the host, a network card with an offload function appears to implement hardware offload for the packets. If the NIC with the offload function is configured as the NIC of the host, some of the...
