Abstract

The present invention relates to a flow monitoring method and device. The method includes: when receiving a message, matching the message with a flow matching strategy, where the flow matching strategy includes a flow identification; if the message matches A flow matching strategy is to insert the INT metadata stack of the INT header for the message, wherein the INT metadata stack includes statistical data on the port of the INT device for the flow identified by the flow identifier; The SDN controller sends the INT header, so that the SDN controller performs traffic monitoring according to the traffic identifier and statistical data included in the INT header. Thus, the monitoring of traffic related to the service can be realized, so that each traffic in the SDN network can be monitored more precisely, and a better basis can be provided for the traffic scheduling to be performed by the SDN controller.

Description

technical field [0001] The invention relates to the communication field, in particular to a flow monitoring method and device. Background technique [0002] Software Defined Network (English: Software Defined Network, referred to as: SDN) is a new network innovation architecture, which achieves flexible control of network traffic by separating the control plane and forwarding plane of network equipment. Inband Network Telemetry (English: Inband Network Telemetry, referred to as: INT) is a network collection technology that can collect and report on the data plane of the network device without the participation of the control plane of the network device. the state of the network. [0003] In the architecture model of INT, it includes INT head node (INT Source), INT transit node (INT transitHop) and INT tail node (INT Sink). The INT head node is also called an INT source device, and the INT source device converts the data packet into an INT packet by adding an INT header to ...
