Our experience showed that there is a direct co-relation 
between the lack of traffic in the upstream direction and 
poor upload bandwidth (primarily, due to asymmetric tech. 
such as ADSL), e.g., because of the ADSL I have at home 
(512Kbps up, 4Mbps down), I generally do not send very large 
e-mails when working from home; nor do I use my laptop for 
remote router/switch updates as the software images are a 
nightmare to upload.

And yes, there is a larger proportion of downstream traffic 
than there is upstream traffic pretty much most of the time 
(even with symmetric links). However, with symmetry, 
upstream traffic will increase significantly as customers 
realize it is now available.

One of the use-cases we thought about when deploying an FTTH 
backbone was having remote PVR's. So rather than record and 
save linear Tv programming on the STB, record and save it in 
the network. This could only be done with symmetric
