Delta compression techniques are commonly used to succinctly represent an updated version of a file with respect to an earlier one. In this paper, we study the use of delta compression in a somewhat different scenario, where we wish to compress a large collection of (more or less) related files by performing a sequence of pairwise delta compressions. The… (More)

We examine the compression and transmission of related web pages using delta compression. Delta compression algorithms exploit the fact that the sender and receiver may both possess a reference file that is very similar to the file that has to be transmitted. Hence, transmitting only the difference between the two files will require a significantly smaller… (More)

This paper examines the compression bene ts that can be obtained by exploiting the possible similarities of pages on the World Wide Web. Two of the elements of our approach are innovative. First, we provide a new di erential compression schemes for similar web pages, which we call wdelta, it is competitive with the current delta algorithm vdelta, and quite… (More)
