A method for sampling of streaming data for distribution on a network (e.g., the Internet) includes receiving the streaming data (which includes periodically updated information items) from a streaming data source. The periodically updated information items of the streaming data are subsequently sampled using a sampling process based on a total update rate of the streaming data (U<SUB>a</SUB>) and a capacity of the network (C), thereby creating a sampled data stream. Alternatively, the periodically updated information items of the streaming data can be sampled using a sampling process that is also based on the importance (K<SUB>qmin</SUB>) of each of the periodically updated information items and the update rate (U<SUB>q</SUB>) of each of the periodically updated information items to create the sampled data stream. The sampled data stream is then distributed on the network (e.g., the Internet or a private area network).
