Embodiment Construction

[0036]The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037]Referfigure 1 The present invention includes the following steps:

[0038]Step 1) Get the training sample set and test sample set:

[0039]Step 1A) Collect the m packets of the wireless communication network data stream, extract the header information of each packet, get the M header information, and then divide each header information according to the fields of the protocol, and divided The field value of the field value is the field value of the field value, and the field value of the same field of the same protocol belonging to the same status is divided into a collection, and finally each collection is a sample, return In the sample set x, m≥100;

[0040]In this embodiment, Wireshark is used to collect packets, because redundancy in the header exists between the header fields of the continuous package of the same protocol in the header, so the c...

Abstract

The present invention proposes a network protocol header compression method based on a decision tree, which is used to solve the problem that the existing network protocol header compression method has a narrow application range. The implementation steps are: (1) obtaining a training sample set and a test sample set; (2) ) Construct a field change feature classification decision tree; (3) The sender uses the field change feature classification decision tree S' to classify the field change features in the header of the compression protocol; (4) The sender and the receiver perform compression negotiation; (5) The sender compresses and transmits the header of the unsent data packet using the protocol to be compressed; (6) the receiver receives the data packet and obtains the decompression result. The present invention adopts field change feature classification decision tree to classify field change features in network protocol headers, and compresses network protocol headers according to classification results. This method can be applied to header compression of most network protocols, and has wide application sex.

Description

Technical field[0001]The present invention belongs to the field of communication, and more relates to a network protocol header compression method, and specifically, a network protocol header compression method based on a decision tree, which can be used in header compression of packets in a wireless communication network.Background technique[0002]The bandwidth of the wireless channel is the most precious and rare resource in the entire wireless communication. Some information in the network protocol header, for end users, it is not necessary to use long-term header information to reduce the payload utilization of the wireless network, thereby wasting wireless channel bandwidth resources. That is, when wireless transmission is performed, if the network protocol header can be compressed, then the transmission efficiency can be greatly improved.[0003]The network protocol header compression method typically includes the transmitter to determine the compressible content in the header, t...
