    CPC classification number: H04L41/0803

    Abstract: A method according to embodiments of this application includes: A first network device sends a first packet to a second network device, where the first packet includes first indication information, and the first indication information indicates a support status of an iFIT capability corresponding to the first network device or a first service module included in the first network device. The first network device sends the packet to the second network device, to notify the support status of the IFIT capability of the first network device. In this way, the second network device can determine, based on the iFIT capability of the first network device, whether to encapsulate a measurement header, to avoid that a service packet cannot be correctly processed because the first network device cannot strip the measurement header from the service packet.

    Abstract: A traffic detection method, apparatus, and system are provided. A first network device obtains a packet, where the packet is any packet of the traffic. The first network device adds a detection flag and detection indication information to the packet to update the packet, where the detection flag is used to indicate a position of the detection indication information, where the detection indication information includes a first flag, and the first flag is used to indicate whether the traffic is to-be-detected traffic. The first network device sends an updated packet to a second network device. According to this method, traffic performance is detected, and flexibility and extensiveness of traffic performance detection are improved.

    Abstract: Embodiments of this application disclose an iOAM packet transmission method and related apparatus. In the method, a tail node device in a measurement domain receives a first iOAM packet, and determines whether the first iOAM packet includes an important data identifier. If the first iOAM packet includes the important data identifier, the tail node device generates, based on the first iOAM packet, a notification message that includes first node information, and sends the notification message to a management device in an iOAM network. According to the solution in the embodiments of this application, only when the received first iOAM packet includes the important data identifier, the tail node device generates the notification message based on the first iOAM packet and reports the notification message.

    Abstract: A method for detecting a multicast service flow includes receiving, by a first node, a multicast service flow from a multicast source; encapsulating, by the first node, an In-situ Flow Information Telemetry (IFIT) extension header into a data packet in the multicast service flow, where the IFIT extension header includes a first detection identifier, and the first detection identifier is used to identify the detected multicast service flow; copying, by the first node according to a quantity of next-hop second nodes of the first node, the data packet encapsulated with the IFIT extension header; and sending, by the first node to each next-hop second node, the data packet encapsulated with the IFIT extension header. The first node is a head node in a multicast detection domain.

    Abstract: Described herein are methods and devices (e.g., routers) that add in-network services to a multiprotocol label switching (MPLS) network. A method can include a router of the MPLS network receiving a packet and modifying the packet by adding one or more MPLS extension headers, adding a header of the extension header(s), and adding an indication within an MPLS label stack that one or more MPLS extension headers have been added to the packet. The method can also include the router forwarding the packet as modified to another router of the MPLS network. In certain embodiments, an extension header label (EHL) within a label value field of a label stack entry indicates that one or more MPLS extension headers have been added to the packet. In other embodiments, a forward equivalent class (FEC) indicates that one or more MPLS extension headers follow the MPLS label stack.
