How do I connect two dsl lines to double my internet speed?

[myronman]

Hello,

I have two dsl lines right now. Is there a way that I can load balance both of these lines on my network so that I can:

Have ftp access doubled
Have internet access doubled
Have the lines shared on my network?

I tried the nexland pro800turbo and that didn't work with ftp. FTP is the most important thing on my list of things I need to work for this setup. I'd like for when one person connect they get full bandwidth of one line, and when another person connects they get full bandwidth of the other line, or actual laod balancing would be even better. Any clues?

Load balancing across multiple IP addresses is not the domain of low end consumer routers. Most of the internet load balancing that I ahve seen involves using BGP (http://www.cisco.com/en/US/tech/tk365/tk80/technologies_tech_note09186a0080094820.shtml). I am not aware of any low end (consumer type) router that handles BGP. The routers that do start in the $3K or so range.

Why not look into buying a faster connection, such as buying a higher bandwidth package, or a T1 leased connection?

not all NSP's offer faster packages and T1's are also very expensive and not always available.

And your better solution would be?

[mbossman2]

if FTP is the most important thing, I would consider co-locating your FTP server somehwere that has outrageous bandwidth capabilities. that would free up a good chunk of your internet capabilities and allow for better sharing.

I didn't have a better solution, just stating facts. Faster ISP/NPS is not always an available option.

I know in some areas, comcast ofters a pro package that is 5-6 mbits down about 640 up with about 5 IP addresses, they charge about 95 dollars a month for that. It is available to me, but I don't have that.

Consider yourself lucky, I live in England, and all consumer DSL accounts (which I'm just comparing, considering we don't have DSL, we have ADSL) only have 256kbps max upload speed, no matter how fast your connection.

The only way I could improve the upload is to purchase a business account, which is expensive.


Hell, I have to pay £27.99 which translates to over $50 a month just for 512/256!

Sanke, I do tech support for ADSL with speeds 1.5 down and 256kbps up. Works good over all, upload speeds max out somewhere around 30KB

it is good if not running a server, but in myronman's case I am sure he would rather have it reversed and have great upload.

What he decribes reminds me of the ISDN connections. but his DSL even single circuit is much faster.

If myronman lives in Chicago, which it states in his personal bar, may I suggest http://chicago.about.com/cs/isps/?

Now, maybe I'm not an expert in everything technical, but google doesn't half come in handy sometimes when you're in a pickle.

go with sdsl for the upload speed

SDSL is cheaper than any T1 out there, but its still pricey in comparison to ADSL.

[mbossman2]

T1's give a little more flexibility than DSL, but their is a price. Many T1 installations are in reality channelized T1 (PRI) installs, this allows X number of channels to be dedicated to voice and Y number of channels dedicated to I-net access. Now there are some companies that are implementing IP based packet switched voice and data lines (Cbeyond is one of them http://www.cbeyond.com/). In addition, T1's also allow you to tie, not only into the corporate frame relay cloud (with the attendant SLA's) as well as the voice network and internet access.

One final advantage for T1's is that they are a mature technology and their reliability is higher than that of DSL. thats why any one running a site for "business" purposes relies on traditional telco lines (t1's, t3's etc) as they tend to be up with much higher erliability than DSL.

Now before you get you're undies in a bunch and say: "Well my DSL is up all the time." What I am talking about is "carrier class" reliability, which approaches (and meets) was is called 5 nines of reliability (99.999%) and if you were betting your business (which REQUIRES the internet to function) then you don't screw around and you go with a T-line.

mbossman2 is very correct on the 5 9's.
I used to work for an ISP and we had a fractional T-1
768 CIR, commented information rate that was burst-able, meaning we could peak above but we had a guarantee of at least 768. If we lost Sync on the T-1 we would have a BST from bellsouth in the building with in 2 hours. We knew our BST on a first name, as he was always hanging out in the shop. We gave him free INTERNET access just to top things off a bit.
