Abstract: This application relates to a slot negotiation method and a device. The method includes: A transmitter sends a first FlexE overhead frame to a receiver, to request active/standby calendar switching. When the receiver is in a restart state, the receiver does not respond to the received first FlexE overhead frame. In addition, the RX sends a routine update second FlexE overhead frame to the transmitter. Determining that the second FlexE overhead frame is not a response to the first FlexE overhead frame, the transmitter sends a third FlexE overhead frame to request active/standby calendar switching again. According to the method in this application, incorrect calendar switching on the transmitter side caused by a mistaken response of the receiver can be avoided. This reduces the likelihood of a service interruption caused by the existing slot negotiation mechanism.

Abstract: A port mode adaptation method includes a network device determining a status of a port on the network device. The method includes the network device setting a mode of the port to an Ethernet interface mode if the status of the port satisfies a first condition. In this way, when the network device identifies the mode of the port on the network device as the FlexE interface mode, and there is no link at the FlexE shim of the port, the network device may determine that a mode used by a port interconnected with the port is not a FlexE interface mode. In this case, the network device may adaptively set the mode of the port to the Ethernet interface mode, to ensure that the port on the network device can use a same mode as another port interconnected with the port.

Abstract: Embodiments of this application disclose a communication method and system applied to an MTN or an SPN. An MTN communication system includes a third communication apparatus connected to the first communication apparatus and the second communication apparatus by using a first MTN path and a second MTN path respectively. If the second MTN path is available, the third communication apparatus transmits data stream corresponding to a first client by using the second MTN path. If the second MTN path is unavailable, the third communication apparatus transmits the data stream corresponding to the first client by using the first MTN path, to ensure normal transmission of the data stream. In addition, the third communication apparatus may further implement load sharing.

Abstract: This application provides a communication method and a communications apparatus. The method can include performing extension based on an existing operation, administration, and maintenance (OAM) packet after an intermediate node in a path of a segment routing traffic engineering (SR-TE) tunnel senses a bit error fault, to support a bit error switching function. That is, the method can include adding, to the OAM packet, identification information used to identify that signal degradation occurs in the SR-TE tunnel. As a result, it is ensured that the SR-TE tunnel supports the bit error switching function of the intermediate node, and a customer service can be effectively prevented from being damaged.

Abstract: This application provides a network performance monitoring method, a network device, and a storage medium, and belongs to the field of network technologies. In this application, a forwarding plane samples network performance data based on a fine-grained time periodicity, and records a quantity of network performance exceptions; and a control plane generates, based on a coarse-grained time periodicity, an alarm when the quantity of network performance exceptions recorded by the forwarding plane is greater than a threshold. On a basis of meeting a fine-grained requirement on network performance monitoring, because the control plane does not need to report all the collected network performance data, a volume of data that needs to be reported by the control plane is greatly reduced. This resolves a problem of overload of a main control CPU that is caused by massive data reporting, and reduces dependency of the network performance monitoring on performance of the main control CPU of a device. This further resolves a problem that a large quantity of bandwidth resources are occupied due to the massive data reporting, reduces dependency of the network performance monitoring on the bandwidth resources, and helps meet a requirement for deploying a large quantity of performance monitoring nodes in a live network.
