Processing method and system capable of supporting network high-level protocols

Abstract

The present invention provides a processing method and system capable of supporting high-level network protocols, comprising: step S1: analyzing the data frame entering the algorithm module, analyzing in detail the values ​​of the data bit fields of the second layer and the third layer, and The field information of the parsed data frame is combined into a 232-bit search slice according to a certain order, so as to be used as a basis for subsequent TCAM search. In the CFP algorithm of the present invention, a TCAM platform is built, and the network high-level protocol is pre-written in the TCAM for comparison. Compared with the currently commonly used data frame filter, it can effectively improve the response rate of the network high-level protocol processing, and can Accurately judge whether the data frame matches the requirements of the network high-level protocol within one clock cycle, and then decide on the subsequent processing plan. An efficient data frame filter can save clock beats for the processing of subsequent data frames, and accurately match the requirements of high-level network protocols for data frames.

Description

technical field [0001] The invention relates to the technical field of network protocols, in particular to a processing method and system capable of supporting high-level network protocols. Background technique [0002] Network protocol: A collection of rules, standards, or conventions established for data exchange in a computer network. [0003] CFP: compact field processor, a multifunctional filter for data classification processing. [0004] During the transmission process of network data links, network nodes usually need to perform different processing for different types of data packets according to network high-level protocols, including speed limit, port mirroring, data forwarding, security blocking, etc. The formulation of the network protocol sets the rules for the data exchange in the network. Through the analysis and processing of the network protocol, it will pave the way for the subsequent transmission path of the data packet. [0005] Generally speaking, the ...

Problems solved by technology

At present, the commonly used data frame filter analyzes the structure of the data frame, and then compares it with the requirements of the high-level network protocol to find out whether it matches the content of the protocol, so as to determine the subsequent processing method, which usually consumes more clock beats and is not effective. high speed filter
