Embodiment Construction

[0031] The present invention will be further described now in conjunction with accompanying drawing.

[0032] The method of the present invention generally includes two stages, the first stage is a training stage, the second stage is a recognition stage, the training stage is used to construct a classifier, and the recognition stage is to use the constructed classifier to identify The protocol format of the received data.

[0033] The method of the present invention will be described in stages below.

[0034] 1. Training stage

[0035] Such as figure 1 As shown, the training phase includes the following steps:

[0036] Step 11), collect the original data samples, and extract the training set from them.

[0037] The data packets transmitted in the network can be used as original data samples after collection, and a training set can be obtained according to these original data samples, and the elements corresponding to a certain original data in the training set are expresse...

Abstract

The invention relates to a construction method of a classifier used in protocol automatic identification. The method includes: collecting original data samples, and extracting a training set from the original data samples; constructing the classifier by the acquired training set; wherein one element in the training set corresponds to one data in the original data samples, each element is expressed as (x(i), y(i)), y (i) is the class label given to the ith data and indicates which protocol the data belongs to, x(i) indicates the feature value and reflects the inherent feature of the data. The invention further provides a protocol automatic identification method on the basis of the classifier. The method includes: extracting the feature values of data after the data is received; substituting the feature values of one data into the classifier to obtain the protocol which the data belongs to.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a protocol automatic identification method and a construction method of a classifier used therein. Background technique [0002] In recent years, with the continuous advancement of the Internet of Things technology, the entire Internet of Things industry has entered a stage of rapid development. A large number of new types of IoT-oriented sensing devices have emerged, and many innovative applications based on the data of these terminal devices have emerged. The basis of all IoT applications is the data collected in the sensor network, so data acquisition is a core content of the IoT. [0003] The Internet of Things is developing very rapidly, but its normative standards lag far behind. Up to now, none of the standards proposed by any organization can be recognized by most practitioners, and judging from the current situation, this is not a problem that can be solved in a sh...
