Abstract

The invention discloses a high-speed message collection network card control method capable of configuring a user-defined Ethernet header. The method comprises the following steps: setting a configuration file, obtaining a user-defined Ethernet header format, performing message parsing according to the user-defined Ethernet header format, calculating a HASH value according to a configured HASH function, and allocating a CPU according to a RETA index. According to the high-speed message collection network card control method disclosed by the invention, by setting the configuration file in a network card, the network card can obtain the user-defined Ethernet header format according to the configuration file and can parse received data messages according to the user-defined Ethernet header, thereby being able to adapt to different user-defined requirements and ensuring that the data messages are allocated to one CPU in a homologous and homoclinic manner.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a control method for a high-speed message collection network card capable of configuring a custom Ethernet header. Background technique [0002] Usually, when receiving packets, the network card can use RSS (Receive Side Scaling) to efficiently distribute the received packets among multiple CPUs. [0003] However, once the user customizes the Ethernet header, the network card cannot correctly identify the length of the Ethernet header, and cannot correctly calculate the quintuple information of the packet, so that it cannot ensure that the packets of the same source and destination are allocated to a CPU, and eventually the application The program cannot efficiently process messages through multiple channels. Contents of the invention [0004] The purpose of the present invention is: in order to solve the above problems in the prior art, the present in...
