Asymmetric networks (ADSL)

I notice that all of the network models assume identical download and 
upload speeds.

Asymmetric networks, such as Asymmetric Digital Subscriber Line (ADSL) 
which sends digital signals over ordinary copper phone lines, are 
common. For example, the currently popular ADSL2+ has 24Mbps  downstream 
and up to 1.4Mbps upstream, while the older but still common ADSL has 
8Mbps  downstream and 448Kbps upstream. These theoretical speeds are 
rarely attained in practice.

(mostly concentrates on downstream speeds)

I *think* that the bottleneck for PFE is downstream throughput, but some 
of the requests for CJK can be quite large and would be affected by 
upstream bandwidth.

I wonder therefore if we should add a Desktop ADSL network model?
