Combining ADSL connections

[guest2013-1]

Would it be possible combining two ADSL connections into one 1 meg connection?

Please someone explain/help?

Why do you have to "put your two cents in"... but it's only a "penny for your thoughts"? Where's that extra penny going to?

Hmmm, me guess's yes but would be difficult. I have never heard any one do it but if you think logically you must be able to. Small ISP's run off 1,2 sometimes 3 diginet line between all there users and this gets split. I am sure there will be software. Maybe connect 2 network cards to an XP machine, plug both ADSL routers to that machine. in properties Bridge the network cards to run off a static ip and then set up that ip as a gateway for the other computers. I am only guesing here though.

No you wouldnt.

Hmmm, yes but they use BGP to balance connections over the lines. That costs big money.

Thats quite an imaginative guess

You might be able to load balance the 2 connections with routing, but the problem is you still wont get 1MBps per connection. You could though if you used a threaded download app.

The 512/256 limit is on the line, not the account, a.f.a.i.k. Karkonosze - so assuming any of the above options work, it would require two lines, no?

 

[James]

I was thinking that they meant 2 lines and two accounts. Oh well, there is my theory shot to shivers. Oh well, I guess you can't then, Still thought my idea was quite cool though.

Yes you can, but it depends what you want to achieve.
You do not actually need BGP to achieve load balancing, it is just currently the most popular way of doing it in certain cases.

If you are trying to have 50 PCs at work browse the net via ADSL, you could easily have half of them use the one line and half the other. Alternatively you can split it so all local traffic goes on the one ADSL line, and all international on the other.

Or you could send all email down one line and all www stuff down the other etc etc etc. There are many ways to skin the cat.

If you have 1 pc and are hoping to download twice as fast from one site, then ....NO its not going to work.

Post some details about what you want to do.

Well, basically a friend of mine that runs a big internet cafe (more than your normal 10-12 PC's) have gotten clients that bitch and moan about the speeds they attain... not that you need much speed to check email, but yea...

He also doesn't want to JUST run half the PC's on one and the other half on the other line (yes, 2 lines, 2 accounts)

So he wants a way you can basically bridge the two ADSL connections into one, he already has a load balancing program where you allocate a specific b/w to each PC (through windows, it's free, but I forgot the URL now, should be somewhere in the MyWireless forums)

The problem just comes in that when all PC's are requesting b/w at the same time that speeds are less than desireable, he also wants people to game locally... any ideas on that?

NOONE - tell your mate that he'd be better-off putting in a Diginet line: his over-riding concern should be customer satisfaction for the sake of his business, so it would be a wise (albeit expensive) investment for sustainable business operations. In other words, he should be doing exactly the opposite of what Telkrap and Sintech are doing to their client base - he must invest in infrastructure...

512K Sentech for browsing customers and ADSL for gaming maybe?

Hard to say depending on the setup. Bottom line is no "bridging" does not double the connection speed.

[TheRoDent]

It's perfectly feasible to share more than one PPP connection. A linux machine, with the "Advanced Router" kernel options enabled is perfectly capable of round-robin load balancing across multiple interfaces without requiring BGP, or anything expensive.

This can be done on a 2.4 kernel as well, using the latest ip-route patches.

yes, but a single TCP "session" would not recive 1Mbps.

The idea is not to get 1meg for a single tcp session, just to combine the two adsl lines into one so that you can spread the connections to the internet more effectively, instead of having one bunch of PC's connect to one line, and the other bunch to the other line, I want all of them to use a "single" line of 1 meg. That way if the one goes down there is at least 512k going around etc.

BTW, how many concurrent gamers do you reckon can play, for instance UT2004 online on south african servers via ADSL without them being affected by lag?

Cause that way I could maybe dedicate one line to the gamers and have a special 3 hours online gaming special on times of the day that it slumps etc.

Oh, btw. By "I", I mean my friend []

Little snippet from the website, sounds nifty:

"Bonding allows you to combine multiple links (e.g. multiple ADSL lines), to effectively give you a single higher bandwidth link (fat pipe). There are many ways of doing this, such as link-layer (e.g. MPPP), IP-layer packet-by-packet, or session-by-session (the latter is often referred to as load sharing)."

well they used to be able to do this with normal modems, aslong as the isp on the other side co operated, then you would get 1 ip, and effectively double the bandwidth

[TheRoDent]

Bonding only works on a PPP level with dialup servers that support it. Currently only ISDN offers MPPP. Telkom's ADSL doesn't allow bonded connections.

Round robin balancing the load across 2 lines is probably the best. UT2003 uses approximately 8kb/s bandwidth, per client, and if you tweak the net settings to lower (56k) even less. You can easily run 6-7 people off a single DSL line without incurring much latency, possibly even more if you tweak the net settings a bit.

The nice thing about DSL is that it doesn't really matter how full the pipe becomes, the latency doesn't increase by much, at least not until you choke it completely.
