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: This application discloses a link-state advertisement LSA sending method, an apparatus, and a system, to reduce a quantity of LSA sending times. The method includes: generating, by a first router, a first path table based on level location information of the first router, level location information of a second router, and level location information of at least one third router; sending, by the first router, a first link state update LSU message to the second router; receiving, by the second router, the first link state update LSU message from the first router; updating, by the second router, a link state database LSDB of the second router based on a first LSA; and sending, by the second router, the first LSA to a router corresponding to an identifier in the first path table.

Abstract: The present disclosure relates to the field of mobile communication, and in particular, to frequency determining technologies in the field of wireless communication. In a frequency determining method, a base station determines a frequency according to different modes, so that an interval between the frequency and a channel raster is not greater than a particular threshold. Corresponding frequencies are determined by setting different thresholds. According to the technical solutions provided in this application, user equipment may determine, in different modes, a corresponding frequency resource to communicate with a base station.

Abstract: Embodiments of the present application disclose a random access method, a base station, and a terminal device. The terminal device receives random access configuration information from a base station, and determines a random access channel, a base frequency, and at least two frequency hopping intervals according to the random access configuration information. The terminal device sends, over the random access channel, random access signals to the base station using frequencies determined according to the base frequency and the N frequency hopping intervals. The terminal device may send the random access signals over the random access channel to the base station according to the base frequency the frequency hopping intervals and a frequency hopping pattern.

Abstract: The present disclosure relates to the mobile communications field, and in particular, to a synchronization signal sending method. A network device obtains a first signal after performing discrete Fourier transform (DFT) and orthogonal frequency division multiplexing (OFDM) modulation, or OFDM modulation on a Zadoff-Chu (ZC) sequence whose root index is 1. The network device obtains a second signal after performing DFT and OFDM modulation, or OFDM modulation on a conjugate sequence of the ZC sequence whose root index is 1. The network device generates a synchronization signal, where the synchronization signal includes the first signal and the second signal. The network device sends the synchronization signal to a terminal device.
