Webproblem is provided in Section III. Finding periodic items is important, and below we show four use cases on ﬁnding periodic item in data streams. Case 1 - Cache: In the Cache scenario [13], the requests of items form a stream, and some requests may arrive periodi-cally. If we can pick out such periodic requests and measure its period, we can ...
