Abstract: In embodiments of this application, the network node may receive a first data packet, where the first data packet carries first traffic feature data of a first data flow to which the first data packet belongs. The network node may determine a data forwarding policy based on the first traffic feature data. Because the data forwarding policy includes a policy used when the network node forwards a data packet included in the first data flow, the network node may forward the data packet based on the data forwarding policy. It may be learned that, in this solution, there is no need for a controller to determine the forwarding policy and the network node to execute the forwarding policy. Instead, the network node may learn of the traffic feature data of the transmitted data flow in real time, and determine and use the data forwarding policy in a timely manner.

Abstract: The present disclosure relates to multicast packet processing methods. One example method includes obtaining a first multicast packet, where destination information of the first multicast packet includes a first identifier indicating link information, a second identifier indicating a replication and forwarding operation, and a third identifier used to index destination information corresponding to a second node, obtaining a second multicast packet based on the first multicast packet and the third identifier, obtaining a third multicast packet, where destination information of the third multicast packet is destination information corresponding to a third node that is determined based on a destination information index corresponding to a multicast packet obtained after the first multicast packet is replicated, sending the second multicast packet to the second node based on the first identifier, and sending the third multicast packet to the third node based on the destination information of the multicast packet.

Abstract: A controller obtains a forwarding latency requirement of a service flow and a destination address of the service flow, and determines a forwarding path that meets the forwarding latency requirement. The controller determines that an ingress node forwards a first cycle time number of a packet and an intermediate node forwards a second cycle time number of the packet, and separately determines a corresponding adjacent segment identifier. A label stack generated by the controller includes the adjacent segment identifier and the adjacent segment identifier. The controller sends the label stack to the ingress node, to trigger the ingress node to forward the packet within a period of time corresponding to the first cycle time number. The controller determines the forwarding path based on the forwarding latency requirement of the service flow, and generates a label stack corresponding to a forwarding time point.

Abstract: This application provides a P2MP tree connectivity detection method, a device, and a system. The method is applied to SR domain. The SR domain includes a P2MP tree. The P2MP tree includes a first node. The first node is a root node or an intermediate replication node of the P2MP tree. The method includes: The first node determines a first next-hop node of the first node based on replication branch information; and the first node sends a first request message to the first next-hop node. The first request message includes a segment identifier SID of the first next-hop node. The first request message includes a first identifier. The first identifier indicates that the first request message is for connectivity detection.

Abstract: This application provides a method and an apparatus for sending a multicast packet. In the method, an ingress device obtains a region identifier of a region corresponding to a received multicast packet. The ingress device obtains, based on the region identifier and a forwarding entry, an address of an intermediate device that is used to forward the multicast packet to the region. The forwarding entry includes the region identifier and the address of the intermediate device. The ingress device sends the multicast packet based on the address of the intermediate device. An intermediate device obtains, based on a multicast packet from an ingress device, a region identifier of a region corresponding to the multicast packet. The intermediate device obtains an address of a next-hop device based on the region identifier and a forwarding entry. The intermediate device sends the multicast packet based on the address of the next-hop device.

Abstract: This application provides a packet transmission method, apparatus, and device. For example, the method is performed by an ingress node. The ingress node obtains a second packet by using first node information carried in a first packet, where the first node information includes a first bit string indicating N next-hop devices of the ingress node and first reference information used for indexing second node information corresponding to a first intermediate node in the N next-hop devices, and the second packet includes a first identifier determined based on the first reference information. The ingress node sends the second packet to the first intermediate node. Because structures of the first bit string and the first reference information are used, a packet encoding manner is simple, so that packet transmission efficiency is improved.
