Embodiment Construction

[0028] In the embodiment of the present invention, the template insertion point is set between each stage of the message forwarding process; when the message needs to be tracked, the pre-configured tracking template independent of the message forwarding processing unit is invoked at the specified template insertion point , matching the packets entering the specified template insertion point with the tracking template, and tracking the successfully matched packets. The tracking template is used to record tracking conditions and describe tracking requirements, and can be flexibly set and modified according to actual application needs.

[0029] The tracking template includes one or more tracking condition values ​​and a mask value corresponding to each tracking condition value, wherein:

[0030] The trace condition value is used to limit the trace condition, and its length is consistent with the length of the packet header where the key field to be traced is located, and the key ...

Abstract

The invention relates to a method for tracing messages and a device thereof, which more particularly comprise that: template insertion points are arranged among all phrases during the forwarding process of the message; preset tracing templates independent from a processing unit of message forwarding are invoked in the designated template insertion points; the message that enters the designated template insertion points are matched with the tracing templates; the message that is successfully matched is traced; the tracing templates are used for recording tracing conditions. The embodiment of the invention realizes message tracing by invoking the tracing templates in the designated template insertion points and modifies the configuration of the tracing templates at any time, thus leading the tracing operation to the message to be separated from the message forwarding process, realizing the dynamic tracing of the message and improving the flexibility of tracing.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and equipment for tracking messages. Background technique [0002] IP (Internet Protocol, Internet Protocol) technology, as the key technology to realize the integration of computer Internet, traditional telephone network and cable TV network, is the development trend of future transmission technology. In order to meet the higher requirements of real-time application services such as voice services and video services based on IP technology on parameters such as delay and QoS (Quality of Service) of the IP network, and improve the quality of the real-time application services, it is necessary to optimize the IP network Real-time monitoring, such as tracking packets. [0003] At present, the tracking of packets in the IP network usually adopts the following implementation methods: [0004] Enable or disable the packet tracking function by setting the status...
