Method, system and device for head compression of packet and service stream classified sending

Abstract

An embodiment of the invention discloses a method of compressing data headers, comprising: receiving data message carried with classification rule identification, finding compressed context corresponding to the classification rule identification, if finding, performing compress treatment on the data header, through comparing the found fields except for the fields included by the classification rule in the compressed context; if not finding, building the compressed context corresponding to the classification rule identification. The embodiment of the invention also discloses a system and a device of compressing data headers, and a method of performing traffic flow soring transmission. According to the invention, treating load of compressing the data headers and performing traffic flow soring on the data message is reduced, system resources are saved.

Description

technical field [0001] The invention relates to the technical field of IP communication, in particular to a method, a system and a device for compressing headers of messages and classifying and sending service streams. Background technique [0002] Worldwide Interoperability for Microwave Access (WiMAX) is a wireless metropolitan area network access technology with a maximum transmission speed of 75Mbit / s and a signal transmission radius of 50 kilometers, which can basically cover the outskirts of the city. Due to this long-distance transmission feature, WiMAX will not only be a technology for wireless access, but also be used as a wired network access, such as optical fiber (Cable), DSL wireless extension, to easily realize network connections in remote areas, and has a wide range of applications. application prospects. [0003] attached figure 1 It is a WiMAX network reference model, and a WiMAX network consists of an Access Service Network (ASN) and a Connection Service...
