AI Technical Summary

Problems solved by technology

During IP FPM detection, if the dyed bit of the target packet conflicts with other services of the target packet, it will not only cause IP FPM packet loss and delay statistics to be wrong, but also affect the forwarding of conflicting service packets

Embodiment Construction

[0085] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0086] In the embodiment of the present application, the coloring bit refers to a bit for characteristic identification of the target packet. When performing packet flow performance measurement, for example, when performing IP FPM detection, the ingress node measures packet loss statistics and delay statistics of target packets by performing periodic feature identification on the dyed bits of the packets. Normally, the colored bits detected by IP FPM are the bits actually used in the message, such as reserved bits of certain fields or bits in reserved fields. In the embodiment of this application, the colored bits detected by IP FPM include The 3rd to 7th bits of the service type field of the target message and the 0th bit of the flag field, a total of 6 colored bits are used as an example for illustration. IP FPM is a technical means that can directly detect t...

Abstract

The invention relates to the field of communications, and in particular to a method for detecting message flow performance. The method comprises the steps as follows: selecting a dye bit to be detected from the message, and then detecting whether there are conflicts between the dye bit of the message and other services of the message; transmitting the configuration information of the dye bit to aningress node and an egress node if there is no conflict between the dye bit and other services of the message; receiving the first statistical data from the ingress node and receiving the second statistical data from the egress node; and obtaining the detection data of the message flow performance according to the first statistical data and the second statistical data. By using the solution, thedye bit is detected before detection of the message flow performance to determine whether there are conflicts between the dye bit and other services of the message, thereby not only improving the detection accuracy of the message flow performance, but also avoiding the conflicts between the message and other services resulting in affecting other services of the message.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method and equipment for detecting message dyeing bit conflicts. Background technique [0002] Internet Protocol (Internet Protocol, IP) Flow Performance Measurement (Flow Performance Measurement, FPM) is a technical means for directly measuring the performance of target packets. Through direct measurement of target packets, IP FPM can obtain performance indicators such as actual packet loss statistics and delay statistics of target packets in the network. The IP FPM coloring bit is the core of the normal measurement and statistics of the IP FPM technology. The IP FPM coloring bit refers to the bit that the ingress node periodically identifies and dyes the target packet. The packets are identified and counted, and the packet loss and delay of the target packet are calculated according to the statistical value of each node and the change of the time stamp at each node along the way...
