The embodiment of the invention provides an in-band telemetering system, method and device, which are used for unloading an acquisition decision of INT information to an edge node by fully utilizing the flexible and efficient capability of the network edge node with flow feature perception, and an intermediate switch acts only according to a specific INT identifier so as to realize flexible and adaptive INT acquisition. The in-band telemetry system comprises a first node, switching equipment and a second node, the first node obtains traffic characteristics of service traffic; determining an INT strategy of the service traffic according to the traffic characteristics; then the first node sends a service message which corresponds to the service flow and carries the INT strategy to the switching equipment; the switching equipment collects INT information corresponding to the service flow according to the INT strategy; the switching device sends the INT information to the second node; and finally, the second node
