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.

Abstract: Various embodiments provide a fault diagnosis method and an apparatus. In those embodiments, a centralized management apparatus receives a first packet from a first network device by using a first IGP monitoring protocol session, where the first packet includes a first message sent by the first network device to a second network device. The centralized management apparatus receives a second packet from the second network device through a second IGP monitoring protocol session, where the second packet includes a second message sent by the second network device to the first network device. The centralized management apparatus performs fault diagnosis based on the first packet and the second packet.

Abstract: A method to perform operations, administrative, and maintenance (OAM) includes a controller generating a policy configuration packet, where the policy configuration packet includes OAM configuration information and information about a first path, and the information about the first path is used to identify the first path. The controller sends the policy configuration packet to a head node of the first path, where the policy configuration packet is used to indicate the head node to perform OAM on the first path based on the OAM configuration information.

Abstract: An information reporting method includes after receiving a Border Gateway Protocol (BGP) flow specification (FS) rule, a network node obtains a status of implementing the BGP FS rule on the network node, where the status indicates that either the BGP FS rule is implemented on the network node or the BGP FS rule is not implemented on the network node. Then the network node sends the status to a server.

Abstract: A label management method includes allocating, by a controller, a source label to a data stream, sending, by the controller, a first Border Gateway Protocol (BGP) update packet to an ingress network device on a label switching path (LSP) of the data stream, and sending a second BGP update packet to an egress network device on the LSP of the data stream, where the first BGP update packet includes a stream identifier of the data stream and the source label, and the second BGP update packet includes a mapping relationship between the source label and a source object of the data stream.

Abstract: A data packet detection method, a device, and a system are disclosed. The method includes: receiving first control information sent by a controller; receiving a first data packet sent by a previous-hop network device of a first network device, where the first data packet includes first detection information, and the first detection information includes a first detection node identifier, a first sequence number, and first collection information; determining, based on the first collection information, first collected data corresponding to the first collection information, and updating the first detection node identifier; and sending, to a next-hop network device of the first network device, the first data packet carrying the updated first detection information. This implements information telemetry on a data packet on a transmission path.

Abstract: In a forwarding parameter obtaining method, a first forwarding device receives a first data packet sent by a second forwarding device on a forwarding path, where the first data packet includes a forwarding parameter monitoring instruction, and the forwarding path is used to forward the first data packet. The first forwarding device obtains, according to the forwarding parameter monitoring instruction, a forwarding parameter used when the first forwarding device forwards the first data packet. The first forwarding device sends the forwarding parameter to a telemetry analysis apparatus.

Abstract: A method, performed by a network node, for enabling Interior Gateway Protocol (IGP) fast convergence, the method includes determining that there is a significant change in link state information, the significant change is at least one of a link down, a link up, and a link metric change. The method further includes originating a link state packet comprising a flag that is set to indicate the significant change in the link state information; and distributing the link state packet.
