摘要： Embodiments of this application provide a packet sending method and a device, to improve packet transmission efficiency. The method includes: A first network device receives a first packet from a second network device, where the first packet includes information about a first forwarding path, and the first forwarding path is a forwarding path for sending the first packet from the second network device to the first network device. The first network device obtains information about a second forwarding path based on the information about the first forwarding path, where the second forwarding path is a reverse path of the first forwarding path. The first network device sends a second packet to the second network device through the second forwarding path, where the second packet carries the information about the second forwarding path.

摘要： Embodiments of this application provide a packet processing method and apparatus, and a communications device. The method includes the following operations: After obtaining first network cost information of a received first packet, a network device may determine a first queue for the first packet based on the first network cost information, and buffer the first packet to the first queue, where the first network cost information is used to indicate a cost for transmitting the first packet to an egress node. Therefore, the network device considers costs for transmitting packets to the egress node, divides queues based on values of the costs that are indicated, and performs differentiated enqueuing operations on the received packets considering the values of the costs.

摘要： A solution for obtaining an interior gateway protocol IGP domain through division in a network is provided. The network includes an access site link and a non-access site link. The access site link includes a link between access site devices and a link between an access site device and an aggregation site device. The non-access site link includes a link other than the access site link in the network. In this solution, a network device determines a changed access site subgraph based on a change of a network topology of the network, and obtains an IGP domain through division based on a link in the changed access site subgraph. The access site subgraph is one or more connection diagrams formed after the non-access site link is removed from the network topology. This solution can improve efficiency of IGP domain division.
