Measurement method of service packet loss rate based on pw in distributed architecture

Abstract

The invention provides a service packet loss rate measuring method based on the PW in the distributed architecture, and relates to the field of distributed architecture. Based on a service disc A and a service disc B, a node A comprises an exit disc A and an entrance disc A, the service disc B comprises an exit disc B and an entrance disc B, the entrance disc A sends a frame loss measuring service request frame to the exit disc A, and the exit disc A is sent to the exit disc B after being added to the service packet sending count of the service disc A; the exit disc B is added to the service packet receiving count after receiving the service request frame and is then sent to the entrance disc B, the entrance disc B replies the service reply frame to the exit disc B, and the exit disc B is then added to the service packet sending count of the service disc B and sent to the exit disc A; the exit disc A receives the service reply frame and is then added to the service packet receiving count of the service disc A, all the counts are finally extracted and transmitted to a main control disc, and the main control disc counts the service packet loss rate according to the counts. By means of the method, the service packet loss rate can be calculated under the condition that the main control disc does not participate in service receiving and sending.

Description

technical field [0001] The invention relates to the field of distributed architecture, and specifically relates to a method for measuring the service packet loss rate based on PW (pseudowire) in the distributed architecture. Background technique [0002] For the centralized architecture, service packets are sent from different egress ports of the service disk, and the packet loss rate of the service can be counted from the service disk, which is easy to count and realize. For the distributed architecture, service packets are sent from the egress ports of different service disks, and the service packet loss rate of this node cannot be directly calculated from a certain service disk. Such as figure 1 In the distributed architecture shown, service packets are sent from the ports of different service disks (service disk 1 and service disk 2). number of packages. In the prior art, due to the distributed architecture, the main control board does not participate in the sending a...

AI Technical Summary

Problems solved by technology

In the existing technology, due to the distributed architecture, the main control panel does not participate in the sending and receiving statistics of the service, so the main control panel cannot calculate the packet loss rate of the service

However, PW-based service establishment needs to pass through two service disks, the egress and the ingress, and the operations of writing the count of sending and receiving packets and extracting the termination of the message cannot be completed independently on the egress or ingress service disk.
