Voip Comparison
Combining (or balancing) two DSL connections?
Good day! I am moving in with a friend who has a DSL line that he uses with gaming.. He has 1.5mbit service in a 3 meg area because it's out in the sticks (cable isn't even available yet) soo, DSL is the only cost attractive option. I have some voip lines, and my PC's, so 1.5 isn't going to cut it. I've already talked to verizon, and they are going to turn up another DSL line to the house. I need to know how to link two DSL modems in a reliable fashon. I've got residental routers out the can, but none with dual wan ports. I was seriously considering using a dedicated PC with 3 nics to do with with linux, but can't find any info on that.. DLink has a dual lan router for about $125 but has had horrible reviews on newegg.. Any suggestions? I can go either with a stand alone router, or a dedicated PC with linux.. (I would rather do linux with how much more I can custo the traffic, etc..) Thanks! To get into a little more detail: I want to link the connections for balancing the total number of uploads/downloads/etc.. I know that you can only technically "bind" the two lines together when you have another box at the other end of the line (at the CO, for instance within the DSLAM to do multiplexing) etc.. I know that with the voip lines, and the different PC's, there are going to be a ton of concurrent connections, and I wanted to use both lines to take care of the need, without splitting the equipment physically between the two modems, as the loads (downloads, uploads) will change between the different sets of PC's, etc.. ...and as for knowing how hard it is to trunk, or bind the two connections together? This is why I'm asking the question.. It isn't an easy thing to do, but I wanted to know if it was possible to do the above :)

- Why do you need them linked? What do you want dual wan ports for? Do you realize how difficult it is to trunk two WAN ports? What if you send one packet from Port A, and the next packet from the Port B, then the third packet from the Port A again? You destroy the sequential nature of the TCP/IP protocol suite. The first packet might have more delay than the second packet, so the second packet might arrive first, then the first packet, then the third packet, among many other unattractive possibilities. Very few SOHO (Small Office Home Office) applications utilize a 2-Port WAN Trunk with any reliability. Far better it would be to put the VoIPs on your DSL with your PC and let him bother with his own internet connection. This would be pretty much the same as the optimal condition provided you do the dedicated PC (custom management) or standalone router. Even if the two connects go to the same ISP, it could destabilize the sequential nature to have it coming through two different sets of twisted pairs.
