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 method for managing a resource object is disclosed. The method executed by a management system includes: adding a mapping relationship between a UUID of a newly discovered resource object and an FDN identifier of the newly discovered resource object to a resource object identifier mapping relationship table; receiving a first query request for a to-be-managed resource object that is sent by an application system, where the first query request is used to obtain an FDN identifier of the to-be-managed resource object; and returning the FDN identifier of the to-be-managed resource object to the application system. According to the method, the resource object in the SDN system can be managed by using the application system by slightly modifying a network management system in an existing network system and an application based on the network management system, thereby implementing smooth evolution of the existing network system to the SDN system.

Abstract: This application claims to protect an active in-situ flow metrics method, a network device, and a system. The method includes: In a detection domain to which in-situ flow metrics are applied, the head node actively generates a detection packet including in-situ flow metrics information and an analog service packet. After receiving the detection packet sent by the head node, the end node detects network performance based on the in-situ flow metrics information carried in the detection packet, terminates the detection packet, and does not continue to forward the detection packet. In the method in this application, an in-situ flow metrics protocol is extended to add an active in-situ flow metrics capability, so that in-situ flow metrics are implemented even when there is no real service traffic, thereby covering various scenarios of network performance detection.

Abstract: This application provides a multicast service providing method and a software defined networking (SDN) controller. The method implemented by the SDN controller includes the operations of: obtaining target path establishment information; obtaining a target multicast IP address corresponding to target service data and a target multicast MAC address corresponding to the target service data; and separately sending a target forwarding rule to a plurality of forwarding devices on the target path. Based on the foregoing technical solution, a service server may send, to a terminal device through unicast, target service data requested by the terminal device. The terminal device may further receive, through unicast, the target service data sent by the service server. In this way, neither the service server nor the terminal device needs to support a multicast protocol.

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: A communication method implemented by a network server, includes: obtaining, based on geographical location information of a plurality of base stations, a first connection relationship between the plurality of base stations; converting the first connection relationship into a second connection relationship based on a first correspondence between geographical location information of a base station and a network element ID of a network device connected to the base station, where the second connection relationship is a topological connection relationship between a plurality of network elements, and the plurality of base stations are respectively connected to the plurality of network elements in a one-to-one correspondence; and generating a service connection configuration of the bearer network based on the second connection relationship. As a result, the service connection configuration of the bearer network can be automatically generated, thereby reducing an error rate and improving work efficiency.
