- the existing packet loss measurement result or the OAM packet loss measurement result is used to detect the signal degradation on the packet path, so that when the rate of the packet path service packet or the OAM packet is small, the packet is not detected. The path signal is degraded.
- the client layer/client sublayer considering that from the statistical point of view, when the service layer/service sublayer is in error, the client layer/client sublayer will have the same probability of error, so the bit error rate of the service layer/service sublayer can be used.
- the bit error rate of the client layer/client sublayer To describe the bit error rate of the client layer/client sublayer. Therefore, in the embodiment of the present invention, the signal degradation result of the service layer/service sublayer is directly used as the signal degradation result of the client layer/client sublayer, which can ensure the reliability of the detection result and simplify the detection process.
- the service layer/serving sub-layer determines that the self-signal degradation comprises: each of the service layer/serving sub-layer corresponding to the packet path in the service layer/serving sub-layer detects its own signal degradation; if each segment of the service layer/servant If any one of the service layer/serving sublayers in the layer detects its own signal degradation, it determines that the service layer/serving sublayer signal is degraded.
- packet path 1 corresponds to three service layer/service sublayers, namely, PE1 and P1, PI and P2, P2 and PE2.
- the three service layer/service sublayers may all generate errors, but the probability of simultaneously generating errors is low.
- the error rate of each service layer/service sublayer is separately monitored, and Use the bit error rate of a certain service layer/service sublayer to describe the bit error rate of the client layer/client sublayer instead of using the bit error rate cumulative calculation for each segment of the service layer/service sublayer commonly used in the related art.

- the packet with the error will be forwarded downstream, so it will be detected again on the downstream link. If a downstream link also has an error, the error will be accumulated on the downstream link. Therefore, if the client layer/client sublayer accumulates the error rate of each service layer/service sublayer, it will cause repeated accumulation. , resulting in inaccurate test results. Therefore, the present invention can reduce the bit error rate sent to the upstream node in the technical scenario that the service layer/serving sublayer does not discard the error-generating message or only the single-segment service layer/serving sub-layer has a bit error.
