Method and system for acquiring state parameters of data stream and computer program product

The invention provides a data flow state parameter acquisition method and system and a computer program product, and relates to the technical field of communication. The data stream state parameter acquisition method comprises the following steps: acquiring subscription requests of one or more data requesters; determining one or more target data streams and one or more first frequencies corresponding to the one or more target data streams based on the data stream identifiers and the first frequencies in the subscription requests of the one or more data requesters; determining a second frequency corresponding to the target data stream based on one or more first frequencies corresponding to the target data stream; obtaining a state parameter of the target data stream based on a second frequency corresponding to the target data stream, and storing the state parameter; and obtaining state parameters from stored state parameters of the target data stream based on the one or more first frequencies corresponding to
