Embodiment Construction

[0059] First, some nouns appearing in the embodiments of this application are explained:

[0060] Various message information can be collected from the message. The message information may include but not limited to: the size of the message, the time interval for receiving the message, the transmission rate of the message, the uplink and downlink ratio of the message, and the number of the message.

[0061] The packet size, that is, the size of the packet, may refer to the total length of a packet or the length of data included in a packet. The packet size can be represented by, but not limited to, the number of bytes. For a message, which part of the message specifically refers to the data contained therein is related to the protocol corresponding to the message. For example, the length of the data is the length of the application layer data included in the message, which is not limited in this application. Taking an Internet Protocol (Internet Protocol, IP) message as an ...

Abstract

The application discloses a flow detection method, comprising: acquiring a plurality of messages collected by a flow collection device in a first time period, the plurality of messages comprising a first data stream and at least one message in a second data stream; determining a target feature set according to the plurality of messages, the target feature set comprising multi-stream features corresponding to the plurality of messages, the multi-stream features comprising statistical parameters of sizes of the plurality of messages; and determining the service type corresponding to the first data flow in the first time period according to the target feature set and the corresponding relation between the target feature set and the service type. According to the flow detection method, more characteristics can be obtained, and the flow detection accuracy can be improved through more characteristic comparison. The invention also discloses a flow detection device which can realize the flow detection method.

Description

technical field [0001] The present application relates to the communication field, and in particular to a flow detection method and flow detection equipment. Background technique [0002] Traffic identification has always been an important research field in Internet data analysis and has a wide range of application scenarios. Traffic identification technology is the basis for fine-grained traffic management and QoE evaluation assurance, and can provide user-level and service-level QoE monitoring and optimization. Traffic identification technology is the basis for operators to conduct precise operations, and can provide services such as OTT user portraits and precision marketing. In addition, traffic identification is also of great value in other scenarios such as network security. [0003] To realize the above-mentioned various services, it is necessary to identify the business type in the traffic, because different business types require different levels of network quality...
