The method comprises: for the upstream optical signal of each Passive Optical Network (PON) port, an Optical Line Terminal (OLT) constructs a short timeslot and transmits it via an optical transceiver; the OLT controls the optical transceiver to conduct a first Signal Detect (SD) sampling detection on the upstream optical signal according to the short timeslot to obtain a first detection result; the OLT judges, according to the first detection result, whether the upstream optical signal is valid; if so, the OLT constructs a long timeslot and transmits it via the optical transceiver, and controls the optical transceiver to conduct a second SD sampling detection on the upstream optical signal according to the long timeslot to obtain a second detection result; and the OLT determines, according to the second detection result, whether the current PON port is experiencing rogue behaviour. The disclosure achieves quick and accurate detection without occupying fixed bandwidth, thus maximizing the utilization of the upstream bandwidth."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for detecting rogue behavior","description":"The disclosure provides a method and device for detecting rogue behaviour.
