Abstract

The embodiment of the invention, which relates to the communication field, provides a method and system for determining a transmission path of a data packet, and apparatuses. Therefore, problems that the determined data packet transmission path is not accurate and the normal data packet transmission is affected because of occupation of lots of network bandwidths during data packet transmission path determination can be solved. The method comprises: a network device determines a data packet; the network device obtains a feature of the data packet and an attribute of the data packet according to the data packet; and the network device sends the feature of the data packet, the attribute of the data packet, and an attribute of the network device to a control device and the control device determines a transmission path of the data packet based on the feature of the data packet, the attribute of the data packet, and the attribute of the network device.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for determining a data packet transmission path. Background technique [0002] In the network, because the data packet transmission path in the service flow is generally determined by the network devices in the network through mutual negotiation and self-selection, the network administrator cannot know the actual data packet transmission path. In the process of monitoring data packets, when a device transmitting data packets fails, it is first necessary to determine the actual data packet transmission path, and then the faulty transmission path or device can be accurately located. [0003] Generally, a method of sending an analog packet is generally used to determine the transmission path of the data packet. Specifically, the source device can send a packet carrying a time-to-live (English: TimeToLive, abbreviation: TTL), that is, an Internet Control...
