Problems solved by technology

Because the station usually contains various types of data service messages, such as MMS, GOOSE, SMV, etc., these messages have their own characteristics, some are burst messages, some are regular messages, some have high real-time requirements, and some are Multicast / broadcast packets, some with large traffic, etc. When these packets with different characteristics are transmitted on the same network with traditional switching equipment, they will cause mutual influence and interference, resulting in a decline in performance or even failure to meet expectations the goal of

Embodiment Construction

[0055] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0056] 1. A protocol analysis method is provided in this embodiment, the method comprising:

[0057] (1) Obtain the business message information transmitted through the S3MII bus;

[0058] The method for obtaining the service message information transmitted via the S3MII bus includes real-time monitoring of the service message information transmitted via the S3MII bus, obtaining bit by bit according to the local reference clock and the control signal of the processor, and storing it in units of bytes;

[0059] (2) Encapsulate as a data frame, and use the FPGA algorithm to quickly analyze each frame of data.

[0060] Encapsulation into a data frame includes: analyzing the frame header by byte, defining the frame format, and obtaining the data field carried after the frame start flag; figure 1 shown.

[0061] Select the frame flag...

Abstract

The invention provides a protocol parsing method and device and a layer-2 exchange system comprising the protocol parsing device. Layer-2 network service messages are recognized and parsed rapidly through a hardware technology and an optimization algorithm, so that smart real-time monitoring of network messages is realized; network service traffic can be managed dynamically in real time; the network security is improved effectively; and a communication network is more smooth and stable.

Description

technical field [0001] The invention belongs to the technical field of intelligent substation communication in a power system, and in particular relates to a protocol analysis method and device and a layer-2 switching system including the protocol analysis device. Background technique [0002] The high intelligence of the power grid puts forward the demand for the power communication system. The digitalization of the whole network information, the networking of the communication platform, and the sharing of the information platform are its basic characteristics, and its development direction is large capacity, fast, high security, and low cost. Ethernet technology is a relatively mature and feasible technology in the field of industrial control at present, and it will be the main technology of power grid communication now and in the future. At present, in the local area network of the power grid system, such as a smart substation, the network communication equipment used for...
