Abstract: A data collection method performed by a collector for communicating with a master station by using DLMS protocol, includes: obtaining a collected-data item identifier from the master station, where the collected-data item identifier indicates a collected data item that needs to be reported to the master station in an event reporting manner; obtaining from a smart meter, to-be-reported data corresponding to the collected-data item identifier; generating a DLMS extension event packet, where the DLMS extension event packet includes a data attribute item and the to-be-reported data, and the data attribute item is used to identify a type of the to-be-reported data; and sending the DLMS extension event packet to the master station. Therefore, message exchange between the master station and the collector and occupied resources can be reduced, and data collection performance can be improved.

Abstract: A traffic detection method, apparatus, and system are provided. A first network device obtains a packet, where the packet is any packet of the traffic. The first network device adds a detection flag and detection indication information to the packet to update the packet, where the detection flag is used to indicate a position of the detection indication information, where the detection indication information includes a first flag, and the first flag is used to indicate whether the traffic is to-be-detected traffic. The first network device sends an updated packet to a second network device. According to this method, traffic performance is detected, and flexibility and extensiveness of traffic performance detection are improved.
