    Abstract: Systems and methods for validating a hardware path capability are provided. The method includes generating, at an ingress node of a network, an operations, administration and maintenance (OAM) probe packet having an OAM bit set associated with validating the hardware path capability, wherein the OAM probe packet comprises a plurality of features; indicating, by each respective intermediate node of a plurality of intermediate nodes in the network along a network path and as instructed by the OAM bit set, whether the respective intermediate node can support the respective feature of the plurality of features; generating, at an egress node associated with the network path, a report regarding whether the plurality of intermediate nodes can support each respective feature of the plurality of features within the OAM probe packet; and determining, based on the report, whether to enable customer traffic implementing the plurality of features along the network path.

    Abstract: A method, network device, and computer program product for network traffic diversion are disclosed. In one embodiment, a method according to the present disclosure includes receiving a frame at a core edge node that is a member of a redundancy group (where the frame comprises network address information and a packet), and determining whether a link is affected by a network failure. The frame was sourced by a remote core edge node that is not a member of the redundancy group, and the network address information indicates that the packet is to be forwarded via the link. In response to the link being affected by the network failure, the method further includes generating a modified frame and forwarding the modified frame to another core edge node. The generating comprises including a redirect label in the modified frame. The another core edge node is another member of the redundancy group.

    Abstract: A method for providing a service for a traffic flow includes a network device receives a first packet; and when a packet feature of the first packet matches a packet feature of the traffic flow, the network device encapsulates an indication identifier of the traffic flow into the first packet to obtain a second packet, and sends the second packet. The second packet is an Internet Protocol (IP) version 6 (IPv6) packet or a Multiprotocol Label Switching MPLS packet. The indication identifier indicates the service provided for the traffic flow.

    Abstract: In some examples, a method includes receiving, by an egress network device for a network, messages from each of a plurality of ingress network devices for the network, wherein each of the messages specifies a multicast source, a multicast group, and an upstream multicast hop weight value for multicast traffic for the multicast source and the multicast group; selecting, by the egress network device and based on the upstream multicast hop weight values specified by the received messages, one of the plurality of ingress network devices to which to send a multicast join message of a plurality of multicast join messages for the multicast source and multicast group; and sending, by the egress network device, the multicast join message to the selected one of the plurality of ingress network devices.

    Abstract: A system including a transmission terminal, used for transmitting a target data packet obtained by encrypting and encapsulating a data flow; a network controller, deployed in a first Internet network and storing routing information from the transmission terminal to a receiving terminal; and a backbone transmission network device, deployed in a backbone transmission network and used for obtaining the routing information and the target data packet forwarded by the first Internet network and forwarding the target data packet to the receiving terminal based on the routing information. The present disclosure solves the technical problem of low efficiency and high cost of data transmission in the conventional techniques.
