Abstract
En 中文
We present a system called the Adaptive Compression Environment (ACE) that automatically and transparently applies compression (on-the-fly) to a communication stream to improve network transfer performance. ACE uses a series of estimation techniques to make short-term forecasts of compressed and uncompressed transfer time at the 32KB block level. ACE considers underlying networking technology, available resource performance, and data characteristics as part of its estimations to determine which compression algorithm to apply (if any). Our empirical evaluation shows that, on average, ACE improves transfer performance given changing network types and performance characteristics by 8 to 93 percent over using the popular compression techniques that we studied (Bzip, Zlib, LZO, and no compression) alone.
