In some types of DSL, the throughput rates for downstream and upstream traffic differ. That is, if you were connected to the Internet via a DSL link, you would be able to download images from the Internet more rapidly than you could send them because the downstream throughput would be greater. A technology that offers more throughput in one direction than in the other is considered asymmetrical. In asymmetrical communications, downstream throughput is higher than upstream throughput. Write a report defending the need for symmetrical systems for the home. What physical infrastructure will it take? What are present or future home applications that require, or will require in the future, higher upstream capabilities?
