Sorry that I'm coming into this thread late (I have just subscribed), but since I see people discussing DSL with beefy upstream, I thought I would be brave and ask: do you esteemed high-end network op folks think that there may be anyone in the world who might be interested in bonded SDSL or not? I have spent the past 5 years of my life learning everything there is to know about SDSL. Don't ask me why, I don't really know the answer to that question myself. I won't waste the bandwidth of this elite list with dirty details of just what I've done with SDSL over the past 5 y, but I'll give a link to an open source project that contains the body of SDSL knowledge amassed over those years: http://ifctfvax.Harhan.ORG/OpenSDSL/ To make the long story short, for most of those years I kept trudging on my project, treating it as an ultra-weird hobby that no one else in the world could possibly have any interest in. That persisted until 2009 when my project got noticed by two fairly major North American DSL network operators. (Well, one very major and one semi-major, but I'll spare the names.) Both of those had contacted me via my Open SDSL Connectivity Project expressing interest in SDSL bonding. Both companies were telling me how much interest they had in SDSL bonding, how much it would help their business to be able to offer bonded SDSL services at 3 or 6 Mbps, how many customers they would be able to sign up for these services, etc. But when I asked them to back their verbally-expressed interest with the tiniest amount of money or even no money at all but a letter of intent which I could show to SBA etc, they both went silent. We've been playing a game of cat-and-mouse ever since. As far as I could understand the existing situation is that the SDSL infrastructure already deployed en masse by the major North American DSL network operators already has the capability to serve out bonded SDSL circuits, bonding either in the DSLAM or somewhere upstream of it, using MLPPP, Multilink Frame Relay or whatever else one can think of, but the problem is with CPE. Apparently bonding-capable multiport SDSL CPE devices are quite scarce. Considering everything I've done with SDSL over the past 5 y, I believe I have a right to say with confidence that I am more than capable of designing and building a bonding-capable multiport SDSL CPE device for any existing SDSL flavor with any desired number of ports (2, 4 or whatever). But what I don't know, and what I'm asking this highly esteemed list for advice with, is this question: is there anyone at all in the world who might have a real serious interest in such a thing? If there is someone in the world who would truly appreciate having a bonded SDSL solution, I would be delighted to work on developing such a thing. I would see it as a service to humanity whereby more use would be made out of existing copper infrastructure in the ground instead of having to dig more ditches to bury more fiber or whatever. But if there is no one in the world who would be interested in bonded SDSL (or at least interested enough to invest one dime into development), then why bother... MS
