Problems solved by technology

However, the processing capability of the smart network card is limited, and there are cases where some packets cannot be processed
Therefore, the aforementioned message needs to be forwarded to the virtual machine manager for processing, resulting in poor effect of the smart network card on reducing the CPU load on the virtual machine manager side

Abstract

The invention provides a message analysis method based on a network card, and the method relates to the network card and a virtual machine manager, and is applied to a cloud computing scene. In the method, a network card can analyze a received message to obtain analysis information of the message, and send the message and the analysis information to a virtual machine manager under certain conditions, so that a plurality of message processing modules in the virtual machine manager can directly process the message according to the analysis information. And the message processing modules do not need to analyze the message again. Therefore, the number of times of message analysis by the virtual machine manager side in the message processing process can be reduced, so that the processing overhead of the CPU of the virtual machine manager side is reduced.

Description

technical field [0001] The embodiments of the present application relate to the field of data processing, and in particular to a network card-based message parsing method and related devices. Background technique [0002] A smart network interface controller (Smart NIC) is a network interface controller with advanced forwarding features, capable of processing network packets. For example, packet forwarding, packet modification, packet checksum calculation, packet aggregation and slicing, etc. The smart network card is often used in combination with a virtual machine manager to reduce the CPU load on the virtual machine manager side, thereby improving the overall processing capability of the virtual machine manager. [0003] In the traditional technology, the intelligent network card reserves some computing instances, which can perform simple message processing such as message forwarding on the message. However, the intelligent network card has a limited processing capabili...
