The high-speed network processing platform provides a high-speed memory system and a hardware acceleration engine, and improves the reading, writing and inquiring performances of the data table items.
The network flow analysis platform is processed by a general arithmetic unit and is compatible with other functions. The role is to identify the session flow. And analyzing the message data, matching some high-level complex rules, and finishing the classification and distribution work of the data.
In this embodiment, network traffic is transported in compliance with the TCP/IP protocol and in compliance with the OSI seven layer model. The interactive message of the application layer of the cross-host generally comprises quintuple information of a source IP address, a destination IP address, a source port number, a destination port number and a transmission protocol number, a session is determined by the quintuple information, the session is divided into uplink data and downlink data, and the uplink data and the downlink data are collectively called a session flow. The conversation flows are composed of interactive message data, and the interactive messages of the first half part of each conversation flow can classify the conversation flows.
The first message data is used for representing the first half interactive message of the conversation flow; the second message data is used for representing the rest message data except the first half interactive message in each conversation flow.
S120, sending the first message data to be analyzed by a network traffic analysis platform to obtain port information of network traffic; the port information is used for representing an output port of network traffic;
the port information is used for representing an output port of the network traffic and is used for carrying out shunting processing on the network traffic. For example, the port information may be a video, a website, MP3, MP4, or the like.
In the scheme, a high-speed network processing platform acquires a session flow of network flow, first message data in the session flow is sent to a network flow analysis platform, and the network flow analysis platform is provided with a rule strategy and a corresponding strategy. After receiving the first message data output by the high-speed network processing platform, analyzing and classifying the conversation flow, and performing rule and strategy matching. If the rule strategy is matched, the port information of the network flow of the high-speed network processing platform is fed back.
In this technical solution, optionally, the sending the first packet data includes:
and if the data volume of the first message data meets a preset data volume constraint condition, sending the first message data.
The preset data amount constraint condition may mean that the data amount of the first packet data is greater than or equal to a preset threshold value. The threshold value may be set according to the data amount of the network traffic. For example, the threshold value may be set to 10, that is, when the data amount of the interaction packet in the session flow of the network traffic acquired by the high-speed network processing platform is greater than or equal to 10, the interaction packet is sent to the network traffic analysis platform as the first packet data, so as to acquire the output port of the interaction packet in the session flow, and complete the shunting of the network traffic.
By processing the first half interactive message of the conversation flow, the processing of the message behind the conversation flow can be processed without using a network flow analysis platform, and the released computing performance can process more conversation flows and increase the processing performance of the whole machine.

And if the rule strategy is matched, the quintuple information and the port information of the network flow of the high-speed network processing platform can be fed back. And the high-speed network processing platform stores the five-tuple information and the port information into the session flow table. The data structure table provided by the high-speed network processing platform can maintain flow table information and support the operations of creation, query, modification and deletion. Each session flow is uniquely determined by quintuple information in the message, so that quintuple data is used as a key value.

For example, fig. 2 is a logic schematic diagram of a network traffic processing process provided in an embodiment of the present application, and as shown in fig. 2, a high-speed network processing platform acquires a session flow of a network traffic, and sends the session flow to a network traffic analysis platform through a load balancing platform, and the network traffic analysis platform analyzes the session flow to obtain feedback information, and sends the feedback information to the high-speed network processing platform through the load balancing platform, so as to implement processing of a subsequent packet of the session flow based on the high-speed network processing platform.
In this technical solution, optionally, processing the second packet data based on the port information includes:
if the port information is not empty, outputting the second message data based on the port information;
and if the port information is empty, discarding the second message data.
In this embodiment, if the high-speed network processing platform obtains the port information of the first packet data after analyzing the first packet data by the network traffic analysis platform, the high-speed network processing platform may output the second packet data based on the port information to implement the offloading of the network traffic; if the port information of the first message data is not obtained, that is, the port information is empty, the second message data can be directly discarded.
By introducing the high-speed network processing platform and cooperating with the existing network traffic analysis platform, a large amount of repeated time-consuming calculation is reduced, and the overall network traffic processing efficiency is improved, so that the performance of the network traffic analysis system is greatly improved.

judging whether quintuple information of the second message data exists in the session flow table or not;
and if so, processing the second message data based on the port information associated with the five-tuple information.
In the scheme, after receiving the feedback information, the high-speed network processing platform updates quintuple information and port information of the session flow into the session flow data, and when a subsequent message of the session flow enters the high-speed network processing platform, the high-speed network processing platform operates the message according to the quintuple information and the port information.
The high-speed network processing platform can quickly match the information matching of the subsequent messages of the conversation flow due to the advantages of the high-speed network processing platform, and the processing of a complex calculation part is avoided.

And after the network traffic analysis platform processes the subsequent packet of the first message data, continuously updating the port information.
The high-speed network processing platform supports the operations of creating, inquiring, modifying and deleting the information in the session flow table. The operation of subsequent messages can be realized based on the session flow table, and the processing efficiency of network flow can be improved.
