I'm using an 584kbps ADSL connection but the speed drops to 64kbps
after I dowlnoad 10GB. It is very expensive to order Flat ADSL where I
live (Macedonia) so I was wondering if it is possible to combine one
ADSL connection that will serve as an upload with other SDSL
connection? If yes, please elaborate how. I would like to implement
this on a network as well.

Make sure you are not confusing bits and bytes (kbps vs. kB/s). Since
adsl upload is slower than download, it is quite possible for your
download to choke if your upload becomes saturated with traffic (public
file sharing, worms/trojans, etc.), because acknowledgements for rec'd
packets have to wait in line with uploaded packets. ToS or QoS queuing
can help (different priority for different types of traffic).
It is relativly easy to have 2 connections for load balancing (used
alternately), fallback (if one fails), or specific routing for specific
networks. But if you want to "bond" 2 connections so one would upload and
other would download, you would need something to bond them on the other
end (ISP or elsewhere on internet) to make the 2 lines work as 1 public
IP. |
