    Abstract: Embodiments of this application provide network traffic marking and measurement methods and a node, and relate to the field of communications technologies, and specifically, to network traffic measurement and network traffic distribution. The network traffic measurement method includes: receiving, by a second node, a data packet sent by another node in a network, where the data packet is periodically marked by the another node, and each node has a different period of marking a data packet. According to the application, the second node may distinguish, based on the period of marking the data packet, traffic sent by the another node in the network, to obtain network traffic sent by the another node in the network to the second node. Upon implementing the traffic measurement method, data plane overheads can be reduced, and a hardware implementation process is simplified.

    Abstract: Embodiments of this application provide a method for transmitting positioning assistance data and a device. The method includes: receiving, by a network device, at least one positioning assistance data message sent by a positioning server, where the at least one positioning assistance data message is used to carry positioning assistance data; and broadcasting, by the network device, a system message to a terminal device, where the system message is used by the terminal device to obtain the positioning assistance data. According to the embodiments of this application, the network device broadcasts the system message to broadcast the positioning assistance data. In this way, a problem of low efficiency of transmitting existing centralized positioning assistance data can be resolved, and a problem in the prior art that a positioning server needs to perform signaling communication with each terminal device in a unicast transmission scenario can be avoided, thereby reducing signaling overheads.

    Abstract: Method and system for setting up a bearer are disclosed. The bearer setup method includes these steps: a packet data network gateway (PGW) obtains first quality of service (QoS) information and a first bearer identifier (ID), and sets up a bearer between the PGW and a radio access network (RAN) according to the first QoS information, where the bearer is associated with the first bearer ID; the RAN sets up a radio bearer (RB) with a user equipment (UE) according to second QoS information associated with the first QoS information, where the RB is associated with a second bearer ID associated with the first bearer ID.

    Abstract: This application discloses a communication method and a related device. The communication method includes: A first in-domain device determines an address length, where the “in-domain” refers to being in a local area network. Then, the first in-domain device receives a data packet, and extracts an address from the data packet based on the address length. Further, the first in-domain device forwards the data packet based on the address.

    Abstract: This application provides a multicast service implementation method and apparatus. The method includes: receiving, by a first network device, a first unicast join message sent by a second network device, where the first unicast join message is used to request to join a multicast group, a source address of the first unicast join message is an address of the second network device, and a destination address of the first unicast join message is a multicast source address or a rendezvous point (RP) address; and establishing, by the first network device, a tunnel from the first network device to the second network device based on the first unicast join message. The multicast service implementation method and apparatus in embodiments of this application help improve availability of a multicast service.
