Abstract
A facility for transmitting data items in a data stream is described. The facility compares the rate at which data items in the data stream are being generated to a threshold rate. When the rate at which data items in the data stream are being generated is no greater than the threshold rate, the facility transmits all of the data items in the data stream to a destination. When the rate at which data items in the data stream are being generated is greater than the threshold rate, the facility transmits only a randomly selected proper subset of the data items in the stream to the destination, such that data items are transmitted to the destination at a rate approximately equal to the threshold rate.
