Abstract
A fundamental technological problem is the transmission of a large amount of data through a network. In this talk, we identify system resources that can be used for compressing transmitted information but, to the best of our knowledge, have not been previously used for this purpose. The two resources we consider are the high bandwidth direction of an asymmetric communication channel and the ability to efficiently broadcast information over a network. For the asymmetric channel, we show that in some scenarios the high bandwidth direction of the channel can be used to significantly compress the information being sent in the low bandwidth direction. For the network with efficient broadcast capabilities, we show that broadcasting can be used to compress information transmitted during multi-processor computation. In both scenarios, we introduce novel compression techniques that demonstrate how to better utilize the existing network resources.
