Symmetrical Cable: Cheap Solution?

If you want a cheap symmetrical connection (usually selling for $100+) get a cable connection with 7Mbps/1Mbps, get a Cisco router and go into your "ip nat inside" interface and issue the command "traffic-shape rate 1048576" there, your own 1Mbps/1Mbps line for a fraction of the price.

=)

Btw, just wondering if there are any provider that actually offers symmetrical cable yet? If so what is the highest upstream they offer?

If you already have a 7Mbps Down / 1Mbps Up connection, what would be the benefit of doing this? On the surface, it appears that you're just throttling back the downstream connection.

There are numerous buisness and other applications that could benifit from symetrical connections e.g. Ethernet bridging over WAN. Making it symmetrical will cause the downstream while operating at full speed to NOT overwhelm the upstream. Since you are only using 1/7th (7 down throttle back to 1 down) you are only using ~14% of your downstream while leaving the other part free. To get additional upstream you can get 2 modems or 3 (still cheaper than getting a dedicated connection with serious bandwidth caps) and bond them using software by FreeBSD called ng_one2many. This will round robin your packets out each of the modems for upstream and in that case you may want to set the throttling of your downstream to match your upstream.

ng_one2many will spoof source IP addresses at Layer 3 and of course TCP packet reassembly will occur at Layer 4 thus ISP is not involved

Doing this is very useful if you want to run something like a VPN server but cannot afford a flow blown symmetrical connection. Just note that if you decide to go and get 6 modems uploading at 6Mbps, and the node is DOCSIS 1.1 (10Mbps max. 6/10 = 60%) this could cripple your entire neighborhood.... I know someone thats doing this with 6 modems

Bottom line: good upload performance cheaper than dedicated line, and the word "Symmetrical" sounds good and professional as opposed to "asymmetrical"

Cheers!

I couldn't agree more, thanks.
