Problems solved by technology

If you need to increase the supported protocol specifications, you need to make incremental additions in the traditional network switching chip protocol pipeline, and sometimes even need to modify the protocol processing flow and architecture, which consumes a lot of development time and hardware logic resources, and often can only increase a specific one or two agreements
In summary, traditional network switching chips have limitations and disadvantages of inconvenient technology upgrades

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0038] Such as figure 1 As shown, the message processing method supporting upper layer software configuration of the present invention comprises the following steps:

[0039] S1) Obtain the network message, extract the message header field and user-defined field, and configure the initial message attribute characteristic value. The user-defined field is the field at the first preset position of the network message. In this embodiment, the user-defined Fields include commonly used information such as MAC addresses and IP addresses, and can also be difficult to handle information, such as the content of optional fields in network protocols;

[0040] S2) Match the user-defined fields and the characteristic values ​​of the initial message attributes in the preset f...

Abstract

The invention discloses a method for generating a network message processing strategy, which comprises the following steps: S1) acquiring a network message, extracting a message header field and a user-defined field, and configuring an initial message attribute characteristic value; s2) matching the user-defined field and the initial message attribute characteristic value in a preset first contentaddressing memory and an analysis strategy table in sequence to obtain an analysis strategy and a corresponding message attribute characteristic value, analyzing the content of the message header field according to an analysis strategy, and replacing the initial message attribute characteristic value with the corresponding message attribute characteristic value; and S3) matching the parsed message header field and the replaced message attribute characteristic value in a preset second content addressing memory and a processing strategy table in sequence to obtain a processing strategy, and generating a corresponding processing action according to the processing strategy. According to the method and the device, the problems of low processing efficiency and inconvenience in upgrading of unsupported or unknown protocol messages are solved.

Description

technical field [0001] The invention relates to a network message processing method, in particular to a network message processing policy generation method, system and medium. Background technique [0002] Currently, traditional network switching chips can only parse and process protocol packets of known formats supported by the chip specification. For unsupported or unknown protocol packets, traditional network switching chips can only discard or send them to the processor for software processing. If you need to increase the supported protocol specifications, you need to make incremental additions in the traditional network switching chip protocol pipeline, and sometimes even need to modify the protocol processing flow and architecture, which consumes a lot of development time and hardware logic resources, and often can only increase a specific one or Two agreements. To sum up, traditional network switching chips have limitations and disadvantages of inconvenient technolo...
