Example Embodiment

[0072] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings of the specification.

[0073] figure 2 It is a flowchart of the first implementation manner of the message parsing and shunting method of the present invention, such as figure 2 As shown, the message parsing method includes:

[0074] Step 201: Receive a message, and obtain the length, source MAC address, destination MAC address, source IP address, destination IP address, and protocol version number of the message, and combine the length, source MAC address, and destination MAC address of the message , The source IP address, the destination IP address and the protocol version number are combined into the key information Key;

[0075] The length of the message refers to the total length of the message received by the device; the source MAC refers to the physical address of the source device of the message; the destinat...

Abstract

The invention provides a message analysis and shunt method and apparatus. The method comprises the following steps: receiving a message and establishing key information Key; querying a preset behaviorpreset table according to the constructed key information Key; judging whether the received message is a large-flow message according to the query result; if so, querying a preset DPI resource analysis table, and obtaining a DPI processing unit that is in an idle state at present; sending the large-flow message to the DPI processing unit that is in the idle state at present to process the message; and sending the message processed by the DPI processing unit to a destination port. According to the message analysis and shunt method and apparatus, classification processing is performed on the message to effectively remove illegal messages and quickly and accurately process the legal messages, thereby improving the processing ability of a large number of messages, making response to the preferred processing of real-time messages with high priority, improving the processing performance of the back end DPI and other network DPI analysis devices, and saving the network resources.

Description

technical field [0001] The invention relates to the technical field of service message analysis, in particular to a method and device for message analysis and distribution. Background technique [0002] With the rapid development of the Internet and the diversification and complexity of network services, the network analysis tasks of communication units are becoming more and more heavy, so higher requirements are put forward for the identification and distribution of network traffic. The identification processing of the existing network flow is mainly based on the packet length value inspection of the first three packets of the network flow extracted from the network flow, so as to identify the type of the protocol to which it belongs. Network traffic identification processing, if the traffic object is small, perform coarse-grained network traffic identification processing. For example, the patent application number is: 201310676369.X, and the name is "A Protocol Identifica...
