I'm considering adding an SDSL line to a small office. Currently, our service is an ADSL with POTS. I was wondering if there would be any issues with using an ADSL and SDSL with a load balanced switch. Would the switch try to compensate between the ADSL dnld upld speed (3.0-6.0M, 512K-768K) and the SDSL dnld upld (1.5M)? Is there a particular model that would be better for this type of setup, or would it be better to have two SDSLs with matched speeds?
wow--a networking question.
So here's the funny thing: I understood the question completely, and all the terminology, but I have no idea what the answer is. I don't deal with complex networking in my day to day (I have a whole team of people for that) and so I have done the following: I asked them.
I'll let you know what I hear back.

So here's what my network guru came back with:

I would need to know lots more about his environment but I doubt he'll have much luck. Generally speaking, one can load balance two circuits to the same provider using a router. (I do per packet load balancing with my two telco T1 lines.) If it is through two providers, one would need something to do per destination load balancing. Otherwise, the source IP address keep changing which hoses up session state and the like. The alternative (but not cheap) is the use BGP to achieve multiple routes. That isn't really a 'load balancing' method though.
Nutshell: What's he trying to accomplish?

So, does this help? And what's your end goal?

Somewhat- ideally, we would be using static IP's from the ISP because we do some HTTPS, SSL and FTP. Basically, I'm trying to create a "poor man's T1". Ideally, I would like to have the load heavy side of the office on the SDSL and the "casual net users" on the ADSL and route the traffic accordingly. Also, it would be the same ISP on both lines (sort of) the static SDSL is a branch company from the main ISP.
You use the word 'ideally' a lot. I find that amusing because I talk all day every day with both my network guys and my security guys about ideal situations (which we never have).
Anywayz--I've passed this back to my network guru.

OK, essentially, to split traffic it's as simple as setting separate gateways for your users and your machines. Servers use gateway A (SDSL) and users use gateway B (ADSL). Essentially any router will be able to do this for you. Depending on your comfort and expertise my network gurus say Cisco is the industry standard.
