Hi guys,

I need to aggregate two 1/2 meg lines, but i'm not sure if this can be done, and if it can, what hardware to use.

I've been told that we cannot get a 1 meg line but it is required for the work that we need to do.

Thanks in advance

What ISP are you using?

There are a couple of different things you can do - but they require special equipment and (usually) a special ISP.

Have you got a budget in mind?
 
If all you wish to do is load balance 2 connections then simply google for a load balancing router, then you can simply interface that with whatever WAN connections you please :)

A Linksys RV042 would do the job.

If he only wants to load balance, which is a fairly inferior way of doing things unless there are lots of users on the end of the ADSL lines downloading...

Yes it would. I suppose its better in that you get the added bonus of a 512kb upstream.

If he's load balancing, one thread won't max out the upstream, which is what most things (i.e. standard FTP) use.

Load balancing is a last resort in my opinion, not the best use of bandwidth in most situations.
 
It sounds as if this is being used in a business environment where they will have multiple users all hammering the connection with loads of threads. Load balancing would be an acceptable solution :)

I wasn't reffering to the router, just the fact that you get twice the upstream bandwidth in general.

The router would be better imo as it's likely to be more stable, which is important for a business environment.
 
Better stability than what though?

Anyway, it's all speculation until the OP responds and tells us what he actually needs the connections for ;)
 
Well answers a question I needed to ask as well, I have a warehouse that needs to access an app via citrix and I can only get 512kb in so was hoping to loadbalance 2 if poss.
 
hmm, load balancing is a bit of a waste of bandwidth in this instance as you are using 2 lines all the time and you may only need one most of the time. It'd be cheaper to got 1meg. Or get a couple of ISDN DDR lines alongside. ISDN DDR can be configured on a cisco Ethernet interface. Basically it's a pain to set up but.....It dials an ISDN line when triggered. I.e when the DSL is full the Cisco instead of routing to that load balances between the DSL and the ISDN. The plus side of this is you only pay for the time you use. It was created as a cheaper small business alternative to leased lines.
 
All true, but the site in question can only get 512 at best :( and ISDN lines are more expensive per month aren't they? if I rememeber correctly..

plus the connection will be used all day by 12 people for citrix access to systems back at the main office and also for access to the security cameras by the security guys at the main office and lastly for net access as well.

That's the point of DDR (dial on demand routing) you only pay for the lines when you use them. Leased lines are VERY expensive, we have 1 meg ones @ about 15k per year. Not cheap, but we have no choice.
 
Why the hell would they want to use old, outdated ISDN lines?

Best option is to go with an ISP like Nildram, 2x512 lines bonded with MLPPP (Sangoma PCI ADSL modems + bonded boot CD) or per packet routing with a Cisco. This would give you 1mbps down and 512kbps up.
 
I think nildram do bonded adsl lines, it was ages ago i last looked, but as far the equipment in the factory was concered it would look like one conection.
Its proper bonding rather than load balancing, try them.
 
how many people access the ctirx app? back in the days of Winframe 1.7 we used a 64kbit leased line for about 20 Users! it was slow but it worked (printing was a absolute nightmre though).

We have a single adsl based vpn to our london office (runs a t256kbit), and it supports 3 users + 1 printer no problem.
