摘要： 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.

摘要： Embodiments of this application disclose a data reporting method. In the method, both a first device and a second device may periodically report iFIT measurement information to a network management device. Specifically, the first device sends iFIT measurement information of the first device to a control and management device at a first moment in a first reporting cycle, and the second device sends iFIT measurement information of the second device to the control and management device at a second moment in the first reporting cycle. The first moment is different from the second moment. Because the first moment is different from the second moment, the control and management device does not receive a large amount of iFIT measurement information in a short time. Correspondingly, this avoids a network congestion problem caused when a data receiving capability of the control and management device is inadequate to receive complete to-be-received iFIT measurement information, and avoids a packet loss of iFIT measurement information caused by the network congestion, so that iFIT measurement information received by the control and management device is more complete. Therefore, a measurement result of an iFIT technology is more accurate.

摘要： 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, if a head node does not receive real service traffic sent by user equipment, the head node actively generates a detection packet including in-situ flow metrics information and an analog service packet. The in-situ flow metrics information is used by a node in the detection domain to perform traffic detection, and indication information included in the analog service packet is used to instruct an end node in the detection domain not to forward the detection packet to another node. 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.

摘要： A method and an apparatus for managing a resource object in an SDN system are disclosed. The method includes: adding, by a management system, a mapping relationship between a UUID identifier 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, by the management system, a first query request for a to-be-managed resource object that is sent by the application system, where the first query request is used to obtain an FDN identifier of the to-be-managed resource object; and returning, by the management system, 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.

摘要： Embodiments of this application disclose a data transmission method, a communication system, and a route advertisement method, to improve data transmission stability when a core network device performs a service. The method includes: An access node sends first traffic to a first core network device in a core network through a first service plane of a bearer network. The access node sends second traffic to a second core network device in the core network through a second service plane of the bearer network. The first service plane and second service plane are independent all-active service planes in the bearer network. Service data sent by the base station is split on the access node, and split data each corresponds to one transmission path, so that the first core network device and the second core network device independently perform data transmission with the access node. Even if one transmission path is completely interrupted, the service data may still be transmitted by another core network device through the other transmission path. This greatly improves network reliability.

摘要： Embodiments of this application disclose a communication method and system applied to an MTN or an SPN. An MTN communication system includes a first communication apparatus, a second communication apparatus, and a third communication apparatus. The third communication apparatus is connected to the first communication apparatus and the second communication apparatus by using a first MTN path and a second MTN path respectively. When the third communication apparatus receives a data stream corresponding to a first client (client), if the second MTN path is available, the third communication apparatus transmits the data stream corresponding to the 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. The third communication apparatus transmits the data stream corresponding to the first client by using the second MTN path, and transmits a data stream corresponding to a second client by using the first MTN path.

摘要： This application provides a packet processing method and a network device. The method includes: A first network device obtains a packet. The first network device adds first indication information and second indication information to the packet, to obtain an updated packet, where the first indication information and the second indication information are located in a multi-protocol label switching MPLS packet header of the updated packet, the first indication information indicates a network slice corresponding to the packet, and the second indication information indicates a forwarding path of the packet. The first network device sends the updated packet to a second network device. A network slice corresponding to a packet and a forwarding path of the packet are respectively indicated in an MPLS packet header via different indication information. In this way, network devices on the forwarding path can normally forward the packet based on unified network slice indication information, with no need to allocate different MPLS labels to the same network slice. This can effectively save MPLS label resources.
