Abstract: The application provides a method: for any network node in a network, the network node may collect a traffic count result of traffic from the network node to a destination network node that belongs to a same area as the network node. Because destination network nodes of the network node are used to indicate an egress node on a path for forwarding a packet by the network node in the area, a control node may learn of, based on count results corresponding to the destination network nodes, traffic transmitted from the network node to egress nodes. This facilitates the control node to determine a traffic distribution feature in the network. The application provides a method that network nodes collect local aggregated traffic statuses, and then the control node determines the traffic distribution feature in the network based on the local aggregated traffic statuses collected by the network nodes.

Abstract: A packet processing method implements a QoS guarantee. The method includes: obtaining a flow identification based on packet attribute information and a flow matching rule, generating a flow policy that includes a correspondence between the flow identification and a flow behavior, determining a forwarding path of a packet including the packet attribute information, sending the flow matching rule to an ingress device of the forwarding path, and sending the flow policy to a first network device on the forwarding path. The ingress device adds the flow identification to the packet including the packet attribute information, and sends the packet. The first network device receives the packet including the flow identification, obtains the flow behavior from the flow policy based on the flow identification, and processes the packet in a packet processing mode corresponding to the flow behavior.

Abstract: This application discloses a service level configuration methods and apparatuses, and belongs to the field of communications network technologies. According to an example method, a target service level used by a first forwarding node to forward a data flow is directly determined based on a transmission parameter of the data flow and service level information of the first forwarding node, and service level configuration is performed on the first forwarding node. Because a transmission parameter of the target service level of the first forwarding node and the transmission parameter of the data flow meet a first target condition, if the first target condition is a delay requirement required by a special service and the first forwarding node transmits the data flow by using the target service level, transmission of the data flow may meet the delay requirement required by the special service.

Abstract: 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.

Abstract: A traffic forwarding method and an apparatus, related to the field of communication technologies, to reduce a rate of traffic loss. The method includes: during graceful restart of a device in a network, when a restart device in the network enters a restart state, a neighbor device of the restart device updates, from first routing information to second routing information, routing information used to forward target traffic. In addition, the neighbor device forwards the target traffic based on the second routing information. The first routing information indicates the neighbor device to send the target traffic to the restart device. The second routing information indicates the neighbor device to send the target traffic to another device.

Abstract: A route sending method and a device are provided. The method includes: A second network device receives a first route sent by a first network device, where the first route includes an IP address of a source network device and first identification information identifying that an IP address of the first network device belongs to a first type, and the first network device is a next-hop network device of the source network device. The second network device sends the first route, where the first route is a route determined by the second network device based on a first route group, and the first route group is determined based on the IP address of the source network device and the first type, so that routes having the same IP address of the source network device but different types of next-hop addresses can be allocated to different route groups.

Abstract: Embodiments of the present disclosure include methods for keeping in a CSFB network and an example user terminal, wherein when a first call of a 4G user fails to be set up, the user terminal keeps in a target network accessed by circuit switched fallback (CSFB). In this way, when the 4G user receives a call request message for the second time, the user terminal does not need to perform CSFB, thereby increasing a call setup success rate. One example method includes obtaining, by a user terminal, a first call request message. The user terminal performs CSFB according to the first call request message to access a target network. The user terminal determines whether a call setup message is received. If no call setup message is received, the user terminal camps on the target network.
