Abstract: Provided is a coding control method in a passive optical network (PON). The method includes acquiring a codeword length N corresponding to a service to be coded; acquiring a matched coding mode corresponding to the codeword length N in a preset table describing a correspondence between codeword length ranges and coding modes; and coding data of the service by using the matched coding mode. Further provided are a coding control apparatus in a PON, a communication device and a storage medium.

Abstract: A method of communication using a forward error correction (FEC) code includes receiving, at an optical line terminal (OLT), performance capability information provided by an optical network unit (ONU), adjusting, at the OLT, a ratio between an FEC code size and a payload size based on the performance capability information, and informing the ONU of the FEC code size selected based on the ratio such that message exchanges between the ONU and the OLT are performed using the FEC code size to which the ratio is applied.

Abstract: Provided are a method and apparatus for generating a topological graph, an anomaly detection method and apparatus, a device and a storage medium. The method for generating a topological graph includes acquiring a preset event stream, where the preset event stream corresponds to a normal log execution path; determining a dependent event pair in the preset event stream; determining a range of a transfer interval corresponding to the dependent event pair, where a transfer interval represents the time difference between adjacent occurrences of two events in the dependent event pair; and generating an event topological graph according to the range of the transfer interval and the transfer probability corresponding to the dependent event pair, where the transfer probability represents the conditional probability between the two events in the dependent event pair.
