Problems solved by technology

The existing technology dynamically compresses the complete content of the message as a unit. Therefore, when only a small part of the content of the two messages is different, it is still necessary to use a compression algorithm to separately compress the complete content of the two messages, which is more efficient. Low

Embodiment Construction

[0048]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0049] In order to describe this embodiment more clearly, a brief introduction to the HTTP message is given below first.

[0050] It should be noted that both the to-be-compressed message and the compressed message provided in this embodiment may be a hypertext transfer protocol HTTP message, a real-time transport protocol RTP message or a real-time streaming protocol RTSP message.

[0051] figure 1 It is a typical HTTP message format, and the message may include t...

Abstract

The present invention provides a message compression method and device. Involved in the field of communication technology. It solves the problem of compressing the packet by compressing the Header and Body together, which increases the complexity of the compression process. The method of the present invention may specifically include: receiving the to-be-compressed message sent by the sending end; acquiring first original content in the invariable part of the to-be-compressed message, and acquiring second original content in the variable part of the to-be-compressed message ; compress the first original content through a static dictionary to obtain the first compressed content, and compress the second original content through a dynamic dictionary to obtain the second compressed content; send a compressed message to the receiving end, and the compressed message includes The first compressed content and the second compressed content. Can be applied to packet compression.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a message compression method and device. Background technique [0002] HTTP (Hypertext transfer protocol, Hypertext Transfer Protocol) is used to describe how a Web client requests a Web page from a Web server, and how the Web server sends a Web page to a Web client and related messages. [0003] Specifically, the basic process of HTTP request and HTTP response may include: when a user requests a Web page by clicking a hyperlink in a Web page or directly entering a URL in a browser, the browser sends each object in the Web page The HTTP request message is sent to the web server. After the web server receives the web request, it includes these objects in the HTTP response message as a response. [0004] In order to adapt to the continuous growth of network traffic, many devices use various means to save bandwidth. HTTP compression is a method of transferring compressed da...
