Embodiment Construction

[0050] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0051] The invention provides a data message transmission processing method, communication equipment and system, which can solve the message packet loss problem in the data message transmission in the prior art.

[0052] Aiming at the problem of IP packet packet loss caused by differences in priorities when IP packet packets of different DSCPs such as voice, video, and Internet services are encapsulated by existing IPSec, the present invention proposes a solution, mainly for IP packet packets of different DSCPs. The text respectively establishes IPSec tunnels, performs DSCP matching thro...

Abstract

The invention is suitable for the technical field of communication, and provides a transmission processing method of a data message, a communication device and system. The transmission processing method comprises the steps: sending a request message carrying out difference service code point (DSCP) information by an initiator device, wherein the DSCP information is used for identifying different service qualities; receiving a returned response message, wherein the response message carries a matching result after the DSCP information is matched; and when the matching result in the returned response message is that the DSCP information is matched unsuccessfully, establishing an IP security (IP Sec) tunnel for transmitting a data message for an IP grouping message corresponding to the DSCP information. The technical scheme provided by the invention can avoid sequence change of the message, therefore, the problem of message packet loss is not caused.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a data message transmission processing method, communication equipment and a system. Background technique [0002] At present, IP networks are widely used, and there are more and more application services. Currently on the same IP network, different types of IP packet messages such as voice, video, and Internet data can be transmitted at the same time. [0003] For different types of IP packet messages, different Quality of Service (QoS, Quality of Service) scheduling priorities can be identified by different Differentiated Services Code Point (DSCP, Differentiated Services Code Point) fields. During QOS scheduling, high-priority IP packets are sent first. When an IP packet message is transmitted through an IP Security (IPSec, IP Security) tunnel, encryption conversion is generally performed. IPSec encrypts and converts packets. The DSCP of the IPSec encapsul...
